As we know, it is a cliché that what we see on the screen is ghosts, phantoms, spectres. What I propose in this essay is that that cliché be taken seriously—do I dare say it, ‘deadly’ seriously—be given rigorous analytic attention for its relevance to the thinking of cinema and its senses, while at the same time acknowledging that even the finest account must come face to face with the ‘fact’ that there is no ghostbuster, not even the analyst/theorist of cinema, not even the Marxist analyst/theorist of cinema, so powerful as to master, defeat and eradicate the spectre of cinema. It is a key premise of this essay that not only is the spectre a privileged subject of film but that it would be the ur figure of cinema, if cinema could have an ur figure, if the spectre could be an ur figure, a figure not only operating at every second at every level in every aspect of every film but also at the level of the cinematic, or rather animatic, apparatus of film, hence at the level of film ‘as such’.

AbstractWe present the estimates of the black hole spins of five quasars. The peaks of the spectra of the accretion discs surrounding massive black holes in quasars are in the far-UV or soft X-ray band, which are usually not observed. However, in the disc corona model, the soft photons from the disc are Comptonized to high energy in the hot corona, and the hard X-ray spectra (luminosity and spectral shape) contain the information of the incident spectra from the disc. The values of black hole spin parameter a are inferred from the spectral fitting, which spread over a large range, ~ −0.94 to 0.998.

Abstract We build a multi-output generative model for quasar spectra and the properties of their black hole engines, based on a Gaussian process latent-variable model. This model treats every quasar as a vector of latent properties such that the spectrum and all physical properties of the quasar are associated with non-linear functions of those latent parameters; the Gaussian process kernel functions define priors on the function space. Our generative model is trained with a justifiable likelihood function that allows us to treat heteroscedastic noise and missing data correctly, which is crucial for all astrophysical applications. It can simultaneously predict unobserved spectral regions and the physical properties of quasars in held-out test data. We apply the model to rest-frame ultraviolet and optical quasar spectra for which precise black hole masses (based on reverberation-mapping measurements) are available. Unlike reverberation-mapping studies that require multi-epoch data, our model predicts black hole masses from single-epoch spectra—even with limited spectral coverage. We demonstrate the capabilities of the model by predicting black hole masses and unobserved spectral regions. We find that we predict black hole masses at close to the best possible accuracy.

Alternate least squares (ALS) reconstructions of the infrared (IR) spectra of the individual layers from original automotive paint were analyzed using machine learning methods to improve both the accuracy and speed of a forensic automotive paint examination. Twenty-six original equipment manufacturer (OEM) paints from vehicles sold in North America between 2000 and 2006 served as a test bed to validate the ALS procedure developed in a previous study for the spectral reconstruction of each layer from IR line maps of cross-sectioned OEM paint samples. An examination of the IR spectra from an in-house library (collected with a high-pressure transmission diamond cell) and the ALS reconstructed IR spectra of the same paint samples (obtained at ambient pressure using an IR transmission microscope equipped with a BaF2 cell) showed large peak shifts (approximately 10 cm−1) with some vibrational modes in many samples comprising the cohort. These peak shifts are attributed to differences in the residual polarization of the IR beam of the transmission IR microscope and the IR spectrometer used to collect the in-house IR spectral library. To solve the problem of frequency shifts encountered with some vibrational modes, IR spectra from the in-house spectral library and the IR microscope were transformed using a correction algorithm previously developed by our laboratory to simulate ATR spectra collected on an iS-50 FT-IR spectrometer. Applying this correction algorithm to both the ALS reconstructed spectra and in-house IR library spectra, the large peak shifts previously encountered with some vibrational modes were successfully mitigated. Using machine learning methods to identify the manufacturer and the assembly plant of the vehicle from which the OEM paint sample originated, each of the twenty-six cross-sectioned automotive paint samples was correctly classified as to the “make” and model of the vehicle and was also matched to the correct paint sample in the in-house IR spectral library.

Annotation:

L’environnement maritime du littoral implique de nombreux processus complexes, mais le manque de données en haute résolution couvrant une large zone sur une longue période est souvent l’obstacle principal à des recherches plus approfondies. Le radar haute-fréquence (HF) est un moyen de faire de la télédétection afin d’obtenir pratiquement en temps réel de l’information sur la surface de la mer et sur une large zone. Ainsi l’étude de l’inversion des paramètres marins à partir de données issues de radars HF est réellement porteuse de sens. Cette thèse fait l’usage d’un jeu de données collectées durant 13 mois par deux réseaux de radar HF à commande de phase pour étudier les caractéristiques de signaux d’échos de la mer, étudier les données à traiter et les méthodes d’inversion, calculer les paramètres de la surface de la mer et évaluer la précision de l’inversion radar des paramètres de la houle.Cette thèse se réfère à l’onde de sol radar HF, dont les ondes radio interagissent avec l’océan du fait de la diffraction de résonance de Bragg. Nous passons en revue l’historique et les applications du radar HF. Nous rappelons les bases de la théorie des ondes électromagnétiques. Nous décrivons les principes d’inversion des courants de surface de la mer, direction du vent et paramètres de houles. La faisabilité de l’inversion de paramètres de houle est examinée. A partir de l’analyse théorique et des études statistiques de nombreux échantillons de données, cette thèse propose une série de méthodes sur le traitement du signal brut et le contrôle de qualité, ce qui inclut la détermination du niveau de bruit, le moyennage des données dans l’espace et le temps, l’identification correcte des pics spectraux, le seuil de largeur de pic, etc. Respectant les caractéristiques de différents processus physiques, les inversions de courant et de vent utilisent des spectres collectés toutes les 20 minutes ; l’inversion des paramètres de houle utilise des spectres moyennés sur 1 heure. Les statistiques des spectres utilisés pour le calcul des paramètres de houle sont présentées pour chacune des stations. Un ensemble de programme efficaces de calculs automatiques avec une complexité algorithme réduite sont développés pour réaliser le traitement et en tirer les paramètres marins.Les vitesses de courants radiales sont obtenues à partir d’une unique station radar. Les champs de vecteurs de courants sont obtenus en combinant chaque station. On montre une année de débit moyen dans la mer d’Iroise, ainsi que le calcul de la vorticité et de la divergence. On étudie un ensemble de données d’un mois du radar SeaSonde de Qingdao. Les schémas de débit moyen, ainsi que la vorticité et la divergence sur un mois sont présentés.La direction relative du vent par rapport à la direction de visée du radar est mesurée à travers le ratio des amplitudes des pics de Bragg. Différents modèles empiriques sont employés pour obtenir la vitesse relative du vent par inversion radar. Les résultats présentés sont en accord avec les estimations prédites par le modèle. Différents modèles de distribution directionnelle sont utilisés pour mesurer le facteur de diffusion pour la mer d’Iroise.Cette thèse se concentre sur l’étude des paramètres de houle. Les résultats sont validés à l’aide de bouées et de données du modèle de vagues (Wavewatch III). L’estimation montre que la précision de la fréquence de houle est très bonne, la précision sur la hauteur significative de houle est très raisonnable et la précision sur la direction absolue de la houle est faible. La cohérence des mesures par chacune des stations radars est vérifiée par comparaison entre les deux. L’utilisation conjointe des échantillons est également prise en charge pour réaliser l’inversion. L’utilisation de deux radars n’améliore pas seulement la précision, mais résout aussi l’ambiguïté de direction relative de houle à partir d’une unique station et donne la direction absolue de vague avec une certaine précision
Nearshore marine environment contains many complex processes, but the lack of high-resolution data over a large area during a long time is often the primary obstacle to further research. High-frequency (HF) radar is a mean of remote sensing which obtains continuous near-real time sea surface information over a large area. Thus the study of inversion of marine parameters from HF radar data is very meaningful. Thisthesis makes use of a 13-month-long dataset collected by two phased array HF radar to investigate the characteristics of the sea echo signals, study the data processing and inversion methods, compute sea surface parameters and evaluate the accuracy of radarinversion of swell parameters.The thesis refers to the ground wave HF radar, whose radio waves interact with ocean by Bragg resonance scattering. The development history and applications of HF radar is introduced. The basic theory of electromagnetic wave is reviewed. The principles of inversion of sea surface current, wind direction and swell parameters are described. The feasibility of the swell parameter inversion is investigated. Based on theoretical analysis and statistical studies of a large number of samples, the thesis proposes a series of methods on raw signal processing and quality control, including the determination of the noise level, data averaging in space and time, the proper identification of spectral peaks, the peak width threshold, etc. Respecting the characteristics of different physical processes, inversions of current and wind use spectra collected every 20 min; inversion of swell parameters uses one-hour averaged spectra. The statistics of qualified spectra for swell parameter calculations are presented for both stations. A set of efficient, with a reduced computational cost, automatic computing programs are developed to do the processing and derive marine parameters. Radial current velocities are derived from single radar station. Current vector fields are obtained by combination of both stations. One-year mean flow field in the Iroise Sea is shown, together with the computation of vorticity and divergence. A one-month SeaSonde radar dataset off Qingdao is studied. One-month mean flow pattern together with vorticity and divergence are presented.Relative wind direction with respect to radar look direction is measured through ratio of Bragg peaks amplitudes. Different empirical models are employed to derive radar-inverted relative wind direction. Results show reasonable agreement with model estimations. Different directional distribution models are used to measure the spreading factor for the Iroise Sea. The thesis focuses on the study of swell parameters. Results are validated by buoy and wave model (WAVEWATCH III) data. The assessments show that the accuracy of swell frequency is very good, the accuracy of swell significant waveheight is reasonable, and the accuracy of relative swell direction is low.Consistency of measurements by both radar stations is verified by comparison between the two. This also supports the use of double samples to do the inversion. Use of two radars not only further improves the accuracy but also solves the ambiguity of relative swell direction from single station and gives the absolute wave direction to a certain precision. The thesis proposes a constant relative directionmethod to derive swell significant waveheight, based on the studies of radar integral equation and the inverted results of relative swell direction. This proposal is demonstrated to improve the agreement of radar inversion and buoy/model provided significant waveheight and increases significantly the number of samples. The thesis investigates the accuracy of swell parameters obtained by HF radar. Contributions of random errors in radar observations are quantified. Comparing the differences between radar and buoy/model estimations gives assessments of the contribution of radar intrinsic uncertainty and contribution of other factors

En zone littorale, la houle subit de fortes transformations par effets bathymétriques. Une meilleure compréhension de ses modifications et des transferts d'énergie associés permet de mieux appréhender les problèmes de dimensionnement de structures côtières et d'aménagement du littoral (protection du littoral, influence des ouvrages sur la côte).
L'objectif de ce travail est d'étudier expérimentalement et numériquement la propagation et le déferlement
d'ondes de gravité.
La première partie, expérimentale, propose des méthodes de calcul, basées sur les houles de Stokes, pour la mesure d'ondes partiellement stationnaires à partir d'instruments de type électromagnétique (S4) ou
acoustique (ADV) donnant des mesures synchrones de vitesses et/ou de pression. Les influences du courant,
de la direction de propagation, de la profondeur d'immersion des appareils ainsi que des effets non
linéaires sont alors étudiés à partir de données en bassin et in situ.
La deuxième partie, numérique, consiste en la validation d'une méthode de suivi de surface libre de type
SL-VOF (Semi-Lagrangian Volume Of Fluid), insérée dans un code de calcul industriel (code EOLE de la
société Principia R&D). L'onde de gravité est modélisée par un soliton. L'étude de la propagation et du
déferlement du soliton est effectuée pour deux applications : sur une marche (discontinuité du fond) puis sur un fond de pente constante 1/15. L'évolution de la surface libre, son élévation et le champ de vitesses
sont alors comparés aux résultats expérimentaux.

L’objectif de cette thèse est d’améliorer les procédures de génération et de qualification des vagues pour les études de génie océanique. Le cadre est limité aux états de mer unidirectionnels générés dans des bassins d’essais expérimentaux et numériques. Les campagnes expérimentales ont été réalisées dans les bassins de l’ECN et les études numériques à l’aide du solveur HOS-NWT développé par l’ECN. Dans la première partie de la thèse, la propagation des états de mer dans les bassins d’essais est abordée d’un point de vue théorique, expérimental et numérique. Une attention particulière est accordée à l’évolution spatiale du spectre et des statistiques. En outre, les incertitudes expérimentales sont étudiées endétail. La deuxième partie de la thèse se concentre sur le contrôle des champs de vague à n’importe quelle position cible dans le domaine. Tout d’abord, une procédure axée sur la qualité du spectre de houle est étudiée. Ensuite, face à l’influence de la position cible sur les statistiques, une nouvelle procédure est introduite. Elle permet de mieux contrôler les distributions statistiques, indépendamment de la position cible
The objective of this thesis is to improve the wave generation and qualification procedures in the context of ocean engineering studies. The framework is limited to unidirectional irregular sea states generated in experimental and numerical wave tanks. Experiments were carried out using the ECN facilities and numerical studies were performed using the nonlinear potential wave solver HOS-NWT developed by ECN. In the first part of the thesis, the problem of irregular wave propagation in wave tank environments is addressed from theoretical, experimental, and numerical points of view. Paticular attention is paid to the evolution in space of the wave spectrum and statistics. In addition, experimental uncertainties arestudied in detail. The second part of the thesis focuses on developing methods to better control the wave fields at any target position in the domain. First, a procedure focusing on the quality of the wave spectrum is studied. Then, facing the dependence of the wave statistics on the target location, a new procedure is developed and tested to better control the statistical distributions independently of the target location

Annotation:

Cette thèse tente d'atteindre deux objectifs : premièrement, produire une analyse générale du cinéma de spectre contemporain dont nous définissons le point de départ en 1998 avec le film Ringu d'Hideo Nakata. Les films de spectres diffèrent des films de fantômes par le fait que leurs motifs sont à comprendre à partir des doutes technologiques, sociaux et métaphysiques de nos sociétés contemporaines. Par ailleurs, ce concept de spectre, que nous définissons tout au long de la recherche, est intrinsèquement lié à l'histoire de l'art et à la philosophie de l'image. C'est ainsi que nous arrivons au second objectif que tente d'atteindre notre recherche : proposer une théorie de notre rapport contemporain à l'image à partir de ce genre cinématographique. L'intuition théorique de départ est que nous vivons à une époque où l'image a une valeur politique prédominante, au point d'influencer l'agir, et que nous pouvons trouver, en l'image elle-même, une matière pour penser cette influence croissante. Ainsi, le cinéma « spectral », en tant que cinéma où le spectre est défini comme « une forme invisible qui va tout faire pour se rendre visible », nous semble être le cinéma même où se jouent cette puissance de l'image et sa part d'incarnation
This thesis attempts to achieve two objectives: first, to produce a general analysis of contemporary cinema of spectre where we define its genesis with Ringu (Hideo Nakata, 1998). What distinguishes spectral films from ghost films is the fact that their patterns are intimately linked to technological, social and metaphysical doubts of our contemporary societies. The concept of spectre, defined throughout this research, is intrinsically linked to the history of art and the philosophy of the image and perception. This is how we arrive at the second objective: to propose a theory of our contemporary relationship to the image based on this cinematographic genre. The initial theoretical intuition is that we live in times where the image has a predominant political value, to the point of influencing action and that we can find, in the image itself, the material for thinking about this growing influence. Thus, the "spectral" cinema, as a cinema where the spectre is defined as "an invisible form which will do everything to make itself visible", is to us the very cinema where this power of the image and its part of incarnation are played out

La propriété de creusement spectral, que l’on retrouve dans certains cristaux dopés aux ions de terres rares refroidis à basse température offre des possibilités prometteuses pour le traitement analogique de signaux radiofréquence. En effet, celle-ci permet de programmer des fonctions de traitement dans le spectre d’absorption du cristal.Partant des premières démonstrations de principe d’un analyseur spectral radiofréquence large bande instantanée, l’objectif est d’en améliorer les performances, ce qui requiert une modélisation précise de l’interaction laser-matière et de l’ensemble des perturbations inhérentes à la montée en maturité technologique du dispositif. Nous avons par conséquent développé un modèle et cherché à étendre son domaine de validité pour qu’il s’applique à un maximum de protocoles.Nous l’avons ensuite appliqué à un matériau en particulier, à savoir un cristal de Tm³ ⁺ :YAG. Après avoir effectué une série de mesures des différentes caractéristiques intrinsèques à ce cristal, nous avons choisi un protocole d’application relativement proche de celui de l’analyseur spectral que nous cherchons à optimiser, à savoir la création de réseaux spectraux large bande. La comparaison des résultats expérimentaux à ceux de notre modèle nous a permis de démontrer sa validité.Nous avons finalement appliqué notre modèle au cas précis de l’analyseur spectral radiofréquence. Les simulations nous ont permis de déterminer théoriquement comment optimiser ses performances, en particulier la dynamique, avec des paramètres réalistes, atteignables expérimentalement
The Spectral Hole Burning property, found in some rare-earth ion-doped crystals at low temperature is particularly relevant for analogic processing of radiofrequency signals. Indeed, it enables processing functions to be programmed in the crystal’s absorption spectrum.Starting with the first demonstrations of a wideband radiofrequency spectrum analyser, we aim at improving its performances, which requires an accurate modelling of the light-matter interaction and all the perturbations arising from the upgrade in TRL (Technology Readiness Level). Therefore, we have developed a model and extended its validity domain to a broad variety of SHB-based protocols.We applied this model on a particular material, namely a Tm³ ⁺:YAG crystal. After measuring experimentally the relevant intrinsic parameters of this crystal, we applied our model to a protocol which is quite similar to the one of the spectrum analyser we aim at optimizing, namely the engraving of wideband spectral gratings. The comparison of our experimental results to the simulations from our model proved its validity.Finally we applied it to the exact case of the radiofrequency spectrum analyser. With the simulations, we determined how to improve its performances, and particularly increase the dynamic range with realistic experimental parameters

The hard X-ray spectrum from black hole candidates, such as 1E1740.7-2942 and Cygnus X-1, has been attributed to an inner hot (Tₑ ≈ 10⁹ K) two-temperature disk which Comptonizes externally produced soft photons from the outer disk. We developed a natural extension of this model, wherein the innermost region of the two-temperature disk, is much hotter (Tₑ ≈ 5 x 10⁹ K) since it is shielded from the external photons and is forced to cool via bremsstrahlung self-comptonization. The emission from this region can account for the long term γ-ray variability in Cygnus X-1. The e⁺e⁻ pairs produced above the hot plasma give rise to the annihilation line observed in 1E1740.7-2942 and the residual pairs form the extended radio jets observed in this source. These early successes called for more detailed modeling of the hot disk. The effects of e⁺e⁻ pairs produced inside the disk were investigated using a better technique for the Comptonization process than what had been reported previously in the literature. This has important quantitative (but no qualitative implications) on the model. Another crucial effect is that of the proton thermal energy being advected to smaller radii. This makes the disk sensitive to the outer boundary conditions (i.e the structure of the transition zone between the outer cold disk and the inner hot region). To determine the physics of the transition region we have developed a scheme for the radiative cooling which is valid at all optical depths. The application of this scheme revealed that the transition region is an extended one. The disk has a hot two-temperature configuration even without the assumption that instabilities in the disk drive the cold disk to this stage (which has been doubted in the past). Moreover, the spectrum from the transition zone matches well with the observed X-ray spectrum of Cygnus X-1 and variations in the magnetic field can account for the two X-ray states. We conclude from this new self-consistent model that the soft X-ray photons observed arise from the cold disk, the X-ray continuum is produced in the transition zone, while the γ-rays and associated phenomena (like the e⁺e⁻ line and the radio jets) are due to the inner hot disk.

Annotation:

La décomposition fonctionnelle dans les équations de Navier-Stokes est un artifice mathématique tirant profit du fait que les échelles des phénomènes associés respectivement à la propagation de la houle et à l'évolution du champ diffracté ( et radié) par un corps sont nettement disctinctes. Les inconnues principales du problèmes sont divisées en une partie incidente représentant la propagation de la houle et une partie diffractée représentant la perturbation due à la présence du corps flottant ou immergé. Cette décomposition est alors introduite dans les équations de Navier-Stokes moyennées au sens de Reynolds. Les termes incidents sont obtenus explicitement sur un modèle de houle incidente en théorie potentielle non-linéaire (plus précisément par une méthode spectrale) et les termes diffractés sont déterminés par la résolution des équations RANS ainsi modifiées. La génération de la houle incidente étant réalisée par un modèle en théorie potentielle, le temps de calcul associé est très faible, la qualité de propagation est optimale et la gamme de houles envisageables est très importante. Cet avantage est combiné à une résolution globale de l'écoulement qui reste néanmoins sous l'hypothèse de fluide visqueux. Ce travail de tehèse constitue une contribution au développement de la méthode SWENSE (Spectral Ware Explicit Navier-Stokes Equations) et propose plusieurs cas de validation en houle régulière aussi bien qu'en houle irrégulière. Les limitations de la méthode sous sa forme actuelle, en particulier la problématique liée à la gestion du déferlement, sont discutées et des réponses pour y faire face sont suggérées
Functional decomposition in the Navier-Stokes equations is a mathematical tool with takes advantage of the fact that the swell propagation and the evolution of the diffracted field from a body are two phenomena with different spatial scales. The principal unknowns of the problem are divided into an incident part representing the swell propagation and a diffracted part representing the perturbation due to the presence of the floating or submerged body. This decomposition is then introduced in the Reynolds-averaged Navier-Stokes equations. Potential flow theory (more precisely spectral methods) is used to compute the incident waves while viscous effects are taken into account by using a modified RANSE solver to obtain the diffracted field in the full domain. By using this approach it is possible to simulate various nonlinear incident waves in an efficient and accurate manner: regular wave trains, focused waves, irregular 2D or 3D sea states. The present work is a contribution to the developent of the SWENSE (Spectal Ware Explicit Navier-Stokes Equations) method and offers several validation cases in regular sea as well as in irregular sea. The limitations of the method in its current form are discussed, especially the over-breaking problem, and answers to them are provided

In this thesis I consider a scheme for quantum computation in which quantum bits (qubits) are stored in individual spectral holes of an in homogeneously broadened medium, such as a cryogenically cooled crystal of Pr:Y2 SiO 3 . Qubits are transferred between spectral holes by virtue of mutual coupling of the atoms to a single quantized cavity mode, which allows for easy implementation of two bit gate operations. I show that laser induced adiabatic passage can be used to transfer an arbitrary symmetric ground state coherence between two many-atom spectral holes. However, it is not clear how to construct entangled states of qubits which are represented by many atoms, and therefore we require that each spectral hole contain only a single atom. The many-atom coherence transfer is still useful for constructing N-photon Fock states in the cavity. The coherence transfer is susceptible to spontaneous emission and cavity decay; the latter is the dominant decay channel for Pr:YSO. I have shown that the coherence transfer can proceed in a cavity dark state which is invulnerable to cavity decay, at the cost of becoming especially susceptible to spontaneous emission, and vice versa for coherence transfer with an atomic dark state. We can achieve the strong atom-cavity coupling necessary for coherence transfer by using extremely high-finesse optical resonators and by reducing the cavity mode volume. The latter is achieved by either reducing the total cavity volume as with a microcavity, or by tightly focusing the mode to a small active volume as with a near-concentric cavity. I consider how the presense of multiple degenerate cavity modes affects the two-atom coherence transfer, and find that the transfer is only exact when both atoms couple to the same mode. For the prototype Pr:YSO material, using a tightly focused mode in a centimeter-length cavity, we can couple as many as 400 qubits with a ground state coherence lifetime of about 1 s, which would allow us to apply as many as 20 sequential gate operations.

It is customary to assume that the optical spectra of glasses have some distinctive features which are caused by two-level systems (TLS) in the host. In the last few years the new data appeared which indicated that TLS can be found in the crystals as well. Among the evidences are the spectral jumps observation in the single molecule spectrum of p-terphenyl doped with pentacene molecular crystal [1], the revealing of the anomalous quasylinear thermal dependency of zero-phonon line halfwidth in the spectra of perylene in n-octane matrices [2,3] etc.

Annotation:

Recent advances in the optical detection and spectroscopy of single impurity centers in crystals has provided the possibility of obtaining information about defect-solid interactions on a truly local level. For the system composed of pentacene impurity molecules in the crystal p-terphenyl, single molecules have been studied using both absorption1 and fluorescence excitation2 techniques at liquid helium temperatures. The superior signal-to-noise of the latter technique has led to direct observations of the lifetime-limited Lorentzian homogeneous profile of a single pentacene impurity3 as well as the surprising observation of spontaneous spectral diffusion4. Spectral diffusion, or changes in the resonance frequency of an impurity molecule with time as a result of low-energy excitations (two-level system transitions (TLS)),5 is generally expected in amorphous hosts. Indeed, the presence of TLSs in amorphous solids is intimately connected with nonphotochemical mechanisms for persistent spectral hole-burning (PSHB) in amorphous materials6-8. Using perylene impurity molecules in poly(ethylene), we have observed the optical spectra of single molecules in a polymeric host for the first time. At 1.5K, individual perylene molecules show the expected spectral diffusion; moreover, we observe light-induced changes in resonance frequency, i.e., persistent spectral hole-burning, which allows one to envision optical storage on the single-molecule level.

Annotation:

Phthalocyanine Lanngmuir Blodgett (LB) films represent ultra thin monomolecular layers with molecules in tight contact. Most of the phthalocyanine molecules in LB films are ordered in domains where they occupy well defined (parallel) positions. There is also a minority of non-ordered molecules in off-domain positions in LB films. This fact is well documented in X-ray diffraction and transmission electron diffraction [1]. Moreover, significant inhomogeneous broadening of absorption spectra of LB film has been observed (see fig. 1), in comparison with absorption spectra of isolated molecules. On the other hand the observed fluorescence is very weak, nevertheless its spectral profile well corresponds to that of isolated molecules. This phenomenon can be well explained on the basis of strong aggregation and/or fast excited energy transfer (EET) [2]. Persistent hole burning (PHB) (in fluorescence excitation spectra) has recently been applied on LB film of related porphyrin - poly-heptyl-cyanoacrylate matrix [3]. The PHB study of tetraaazoporphyrin in LB films suggested this EET interpretation. The role of EET in free base phthalocyanines was also discussed in [4] together with the analysis of off-resonant holes in fluorescence spectra. The aim of this paper is to determine the excited state lifetimes T1 strongly influenced by fast EET from PHB measurements (in fluorescence excitation spectra).

Annotation:

Underlying structure for the primary donor absorption profiles of isolated reaction centers Rhodopseudomonas viridis and Rhodobacter sphaeroides (P960 and P870) has recently been uncovered by transient hole burning experiments [1]. A Franck-Condon progression of an intermolecular special pair marker mode (ωsp) was found to originate in the low energy shoulder of the absorption spectra and peak at the one quantum transition. The theory of Hayes and Small [2] for fitting hole burned spectra was extended to include the coupling of the marker mode. Briefly, the theory defines a single site absorption function as being made up of a sum of 0-,1-,… phonon lineshape functions composed of a gaussian distribution for the low energy side and a lorentzian for the high energy side. By constructing a gaussian distribution whose full-width at half maximum is equal to the inhomogeneous broadening and convolving with the single site absorption function, the absorption spectrum is obtained. By further convolving these functions with an exponential decay function of the single sites centered at the bum frequency the absorption spectra after burning a time T is obtained. Important parameters include the Huang-Rhys factor for the phonons and marker mode S,Ssp, the mean phonon frequency ωm, the marker mode frequency ωsp, the width of the one phonon profile Γ, the zero-phonon width γ, and the inhomogeneous broadening Γ1. Most of the parameter values required in the fit can be obtained from experiment. An important test for the theory is how well it can account for the bum wavelength dependence of the hole spectrum.

Spectral hole-burning is powerful tool for the study of fast relaxation processes (e.g. excited energy transfer - EET, electron transport - e.t.) in photosynthetic systems. Fast e.t. was systematically studied by transient hole-burning (THB) in absorption spectra of reaction centra in purple bacteria and green plants [1]. The THB in fluorescence of PSII particles was described in [2]. Persistent spectral hole-burning (PSHB) enabled to determine the hole-burning mechanism, the EET rate constants, electron-phonon coupling and frequency of protein phonons. The PSHB in fluorescence has been measured in antenna complexes: CP43 and CP47 of PSII [3], B800-850 of purple photosynthetic bacteria [4] and in chlorosomes of green sulphur photosynthetic bacteria [5]. Laser induced hole filling in fluorescence spectra of CP43 of PSII was presented recently in [6]. These data were obtained using wild type organisms. Here, we report an investigation of EET by fluorescence PSHB in photosynthetic antenna using H114Q mutation in the CP47 complex of Synechocystis sp. PCC 6803.

J-aggregates of cyanine dyes show a sharp absorption peak, called J- band, below the transition band of monomers [1,2]. The band is due to the transition of excitons delocalized over an aggregate by intermolecular dipole interaction. A simple model of N identical molecules aligned in a one- dimensional chain has been proposed to explain the optical spectrum of the J- aggregates [3-5]. Recently, we have developed a new method, named "vertical spin-coating", to prepare highly oriented J-aggregates dispersed in polymer films [6]. Linear dichroic spectra, and electro-absorption spectra have been measured to study the optical properties of one-dimensional excitons in J- aggregates [7,8].

In this presentation we report on several spectral features associated with Si impurity in diamond related to spectral hole-burning. Diamond, with its hardness and high temperature stability, is a potentially useful material for high temperature hole-burning storage. The first hole-burning in bulk diamonds [1] was observed from color centers in the spectra of N3 at 415 nm, H4 at 496 nm, N-V at 637 nm, and GR1 at 741 nm. Recently, hole-burning was observed for color centers N-V at 637 nm and 574 nm of electron irradiated chemical-vapor deposited (CVD) diamonds [2].
