Iskandar, Abdo. "Phonon Heat Transport and Photon-phonon Interaction in Nanostructures." Thesis, Troyes, 2018. http://www.theses.fr/2018TROY0010.
In this dissertation, we investigate phonon heat transport and phonon interaction with optical elementary excitations in nanostructures. In the first chapter, we present an introduction to the physics of phonons and optical elementary excitations in nanostructured materials. The second chapter provides a detailed description of the samples growth and fabrication procedures and the various characterization techniques used. In the third chapter, we demonstrate that phonons and photons of different momenta can be confined and interact with each other within the same nanostructure. In the fourth chapter, we present experimental evidence on the change of the phonon spectrum and vibrational properties of a bulk material through phonon hybridization mechanisms. We demonstrate that the phonon spectrum of a bulk material can be altered by hybridization between confined phonon modes in nanostructures introduced on the surface of the material and the underlying bulk phonon modes. Shape and size of the nanostructures made on the surface of the substrate have strong effects on the phonon spectrum of the bulk material itself. In the fifth chapter, we demonstrate that at low temperatures (below 4 K) the nanowire specific heat exhibits a clear contribution from an essentially two-dimensional crystal. We also demonstrate that transitions from specular to diffusive elastic transmission and then from diffusive elastic to diffusive inelastic transmission occur at the interface between nanowires and a bulk substrate as temperature increases. Perspectives include the control of bulk material thermal properties via surface nanostructuring

In this thesis, we study optomechanic interactions in phoxonic crystals which are defined as dual phononic/photonic crystals that can exhibit simultaneously phononic and photonic band gaps. The existence of absolute band gaps allows the simultaneous confinement of both waves that, in turn, can produce the enhancement of their interaction for the purpose of novel and high-performance optomechanical and acousto-optic devices and applications. A main objective is the modulation of light by acoustic waves when both excitations are confined inside the same cavity or propagate with a slow group velocity inside a waveguide. We have studied theoretically the optomechanic interactions in different (2D, slabs and strip) phoxonic crystals cavities. We have demonstrated the dependence of these optomechanic interactions as a function of both the nature of the material and the incoming optical wavelength. The results for strip waveguides have been compared with experimental results performed by our partners. Finally, as a perspective, we began to study the phonon-plasmon coupling

Developments in quantum information processes require the use of solid state qubits that would emit on demand single and indistinguishable photons. Semiconductor quantum dots (QDs) show an atom-like spectrum which makes them attractive in this regard. However, a single QD constitutes an open quantum system coupled to its surrounding solid-state environment, the phonon bath and the fluctuating electrostatic environment. This has important consequences on the coherence properties of the electronic system and the QD is a probe to study these fundamental interactions. Using Fourier spectroscopy and temperature-dependent resonant HOM experiments we show that these two mechanisms occur on very different time scales: spectral diffusion is a slow dephasing process acting on microseconds, while phonon interaction takes place in less than one ns. Then, the loss of ndistinguishability in HOM measurements is only related to dephasing induced by the coupling to the phonon bath. The TPI visibility is preserved around 85 % at low temperature, followed by a rapid loss of coherence. To fully understand the experimental results we developed a mircroscopic model for the electron-phonon interaction which allow to obtain analytic expressions for the dephasing rates. Below 10K the relaxation of the vibrational lattice is the dominant contribution to the loss of TPI visibility. This process corresponds to real phonon transitions resulting in a broad phonon sideband in the QD emission spectra. Above 10K, virtual phonon transitions to higher lying excited states become the dominant dephasing mechanism, leading to broadening of the zero phonon line and a corresponding rapid decay in the visibility

Geondzhian, Andrey. "Resonant inelastic X-ray scattering as a probe of exciton-phonon coupling." Thesis, Université Grenoble Alpes (ComUE), 2018. http://www.theses.fr/2018GREAY077/document.
Phonons contribute to resonant inelastic X-ray scattering (RIXS) as a consequence of the coupling between electronic and lattice degrees of freedom. Unlike other techniques that are sensitive to electron-phonon interactions, RIXS can give access to momentum dependent coupling constants. Information about the dispersion of the electron-phonon interaction is highly desirable in the context of understanding anisotropic conventional and unconventional superconductivity.We considered the phonon contribution to RIXS from the theoretical point of view. In contrast to previous studies, we emphasize the role of the core-hole lattice coupling. Our model, with parameters obtained from first principles, shows that even in the case of a deep core-hole, RIXS probes exciton-phonon coupling rather than a direct electron-phonon coupling.This difference leads to quantitative and qualitative deviations from the interpretation of the implied electron-phonon coupling from the standard view expressed in the literature. Thus, our objective is to develop a rigorous approach to quantify electron-phonon coupling within the context of RIXS measurements. The ability to accurately reproduce experimental results from first-principles calculations, without recourse to adjustable parameters, should be viewed as the ultimate test of a proper understanding of the phonon contribution to RIXS.We start by considering only the core-hole--phonon interaction within the context of X-ray photoemission spectroscopy. We combine an ab initio calculation of the real-space response function with many-body Green's functions techniques to reproduce the vibrational side-bands in SiX4 (X=H, F) molecules. The approach we developed is suitable for application to crystalline materials.We next consider the phonon contribution to X-ray absorption spectra. Unlike the charged excitations generated by X-ray photoemission, X-ray absorption creates a neutral excitation that we approximate as a core-hole and an excited electron. We first solved the electronic part of the problem on the level of the Bethe-Salpeter equation and then dressed the resulting 2-particle excitonic quasiparticle with the exciton-phonon interactions using the cumulant ansatz. The viability of this methodology was tested by calculating the N K-edge XAS of the N2 molecule and the O K-edge of acetone. The resulting vibronic spectra agreed favorably with experimental results.Finally, we construct a hybrid formulation of the RIXS cross section that preserves explicit summation over a small number of final states, but replaces the summation over intermediate states, which might be enormously expensive, with a Green's function. We develop an expansion of the Green's function and derive both analytically exact (in the no-recoil limit) and approximate solutions. The formalism was again tested on the O K-edge of acetone and agrees well with the experiment. To provide an outlook towards future work, we discuss application of the developed formalism to crystalline materials

Dans un premier temps, l'interaction électron-phonon ainsi que trou-phonon est étudiée expérimentalement par spectroscopie dans l'infrarouge lointain (50-700 cm-1) sous champ magnétique intense (0-28 T). L'intérêt d'un champ magnétique est de déplacer les transitions électroniques, afin de les amener en résonance avec les phonons, là où les effets du couplage sont le plus évidents. Pour interpréter les résultats expérimentaux, nous avons calculé le couplage entre les états électroniques et les états de phonons LO en utilisant l'Hamiltonien de Fröhlich. On détermine ainsi les états polarons et les forces d'oscillateurs, qui sont en bon accord avec les résultats expérimentaux.
Dans un deuxième temps, nous étudions le couplage des paires électron-trou ou excitons avec les phonons LO. Les transitions interbandes sont sondées dans des expériences de magnetophotoluminescence pour des champs magnétiques allant jusqu'au 28 T. A cause des fluctuations de taille, de composition, et de forme des boîtes quantiques auto-organisées, les pics de photoluminescence sont élargis d'une façon inhomogène. Pour minimiser cet élargissement, des expériences de photoluminescence résonante et d'excitation de la photoluminescence sont effectuées, pour lesquelles un sous-ensemble de boîtes homogènes est sélectionné. Nous calculons les états de polarons excitoniques, ce qui nous permet de déterminer le spectre d'absorption des boîtes quantiques. Un bon accord théorie-expérience est obtenu.

The study of the out of equilibrium dynamics of strongly correlated systems, using ultrafast pulses, uncovered a plethora of phenomena with no analog in equilibrium physics. In this thesis, we theoretically investigate the out of equilibrium dynamics of the lattice degrees of freedom and their signature in pump-probe spectroscopy. We develop a Hamiltonian-based microscopic description of laser pump induced displacive coherent phonons. The theory captures the feedback of the phonon excitation upon the electronic fluid, which is missing in the state-of-the-art phenomenological formulation. We show that this feedback leads to chirping at short timescales, even if the phonon motion is harmonic. At long times, this feedback appears as a finite phase in the oscillatory signal. We apply the theory to BaFe2As2, explain the origin of the phase in the oscillatory signal reported in recent experiments, and we predict that the system will exhibit redshifted chirping at larger fluence. Our theory also opens the possibility to extract equilibrium information from coherent phonon dynamics. Another interesting phenomenon that have been reported in pump-probe spectroscopy is the oscillation of the lattice fluctuations at double phonon frequency. These oscillations are invariably interpreted as a signature of macroscopic squeezed phonon states. In this work, we identify other mechanisms of double phonon frequency oscillations that do not involve squeezing. We show that a pump induced temperature quench of the bath, to which the phonon is coupled to, or exciting a coherent phonon for which cubic anharmonicity is allowed by symmetry can also produce such oscillations in noise spectroscopy without squeezing the phonon state. We conclude that, in contrast with what is commonly believed, double phonon frequency oscillations in noise spectroscopy are not necessarily a signature of macroscopic phonon squeezing. We point out what can be a reliable criterion to identify a squeezed phonon using pump-probe spectroscopy
