Abstract (sommario):

I explore visual and process-based systems to solidify the allusive nature of conceptual ideas. Impermanence, time and interdependence are reoccurring themes that stem from an interest in Eastern philosophy. Oscillating from representation to abstract minimalism, printmaking to sculpture, each element in a work is tailored to the concept. The minimalist appearance suggests simplicity, however elaborate planning and systematic execution are at the heart of my practice. Systems create great constraint, yet provide great freedom.

Abstract (sommario):

We consider the finite two-dimensional Ising model on a lattice with periodic boundaryconditions. Kaufman determined the spectrum of the transfer matrix on the finite,periodic lattice, and her derivation was a simplification of Onsager's famous result onsolving the two-dimensional Ising model. We derive and rework Kaufman's resultsby applying representation theory, which give us a more direct approach to computethe spectrum of the transfer matrix. We determine formulas for the spin correlationfunction that depend on the matrix elements of the induced rotation associated withthe spin operator. The representation of the spin matrix elements is obtained byconsidering the spin operator as an intertwining map. We wrap the lattice aroundthe cylinder taking the semi-infinite volume limit. We control the scaling limit of themulti-spin Ising correlations on the cylinder as the temperature approaches the criticaltemperature from below in terms of a Bugrij-Lisovyy conjecture for the spin matrixelements on the finite, periodic lattice. Finally, we compute the matrix representationof the spin operator for temperatures below the critical temperature in the infinite-volume limit in the pure state defined by plus boundary conditions.

Abstract (sommario):

Abstract This thesis project is divided in two parts. The first part examines the possibility that correlation matrix estimates based on an outlier sample would contain information about extreme events. According to my findings, such methods do not perform better than simple shrinkage methods where robust shrinkage targets are used. The method tested is especially outperformed when it comes to the extreme events, where a shrinkage of the correlation matrix towards the identity matrix seems to give the best result. The second part is about valuation of skewness in marginal distributions and the penalizing of heavy tails. I argue that it is reasonable to use a degrees of freedom parameter instead of kurtosis and a certain regression parameter, that I develop, instead of skewness due to robustness issues. When minimizing the one period draw-down is our target, the "value" of skewness seems to have a linear relationship with expected returns. Re-valuing of expected returns, in terms of skewness, in the standard Markowitz framework will tend to lower expected shortfall (ES), increase skewness and lower the realized portfolio variance. Penalizing of heavy tails will most times in the same way lower ES, lower kurtosis and realized portfolio variance. The results indicate that the parameters representing higher order moments in some way characterize the assets and also reflect their future behavior. These properties can be used in a simple optimization framework and seem to have a positive impact even on portfolio level

Abstract (sommario):

Thermodynamics traditionally deals with macroscopic systems at thermal equilibrium. However, since the very beginning of the theory, its range of applicability has only increased, nowadays being applied to virtually every field of science, and to systems of extremely different size. This thesis is devoted to the study of thermodynamics in the quantum regime. It contains original results on topics that include: Work extraction from quantum systems, fluctuations of work, the energetic value of correlations and entanglement, and the thermodynamics of closed quantum many body systems. First, we study work extraction from thermally isolated systems. Here the notion of passive states naturally arises, as those quantum states from which no work can be extracted. We start by characterising the set of passive states, and find the most energetic passive states, a dual family to the well known Gibbs (or thermal) states. Remarkably, passive states have the property of activation: When considered as a whole, several copies of passive states can become nonpassive. We study the dynamics of activation processes, and find a relation between the entanglement generated and the speed of the process. Next, we consider the possibility of extracting work from a system using an auxiliary thermal bath. In this case, according to the second law of thermodynamics, the amount of work is bounded by the free energy difference. We develop corrections to this law which arise from the finite size and the structure of the bath. We go on by studying the fluctuations of work. Fluctuations are particularly relevant for small systems, where their relative size is comparable to the average value itself. However, characterising the fluctuations in the quantum regime is particularly difficult, as measurements generically disturb the state. In fact, we derive a no go result, showing that it is not possible to exactly measure the fluctuations of work in quantum coherent processes. Despite this result, we develop a new scheme that allows for their approximate measurement. An important part of this thesis is devoted to the relation between quantum correlations and work. We start by considering a set of correlated states which are thermal at the local level, in which case the extractable work can only come from the correlations. We compute the amount of work that can be stored in entangled, separable and correlated states with a fixed entropy, by finding the corresponding optimal states and protocols. These results provide fundamental bounds on the potential of different type of correlations for work storage and extraction. Next, we consider the converse scenario, and study the creation of correlations from thermal states. We find thresholds on the maximal temperature for the generation of entanglement. We also work out the minimal work cost of creating different types of correlations, including total correlations, entanglement, and genuine multipartite entanglement. Finally, we study the thermodynamics of closed quantum systems. Here we use one of the most important recent insights from the study of equilibration in quantum systems: Closed many body systems do not equilibrate, but can be effectively described as if they had equilibrated when looking at a restricted, physically relevant, class of observables. Importantly, the corresponding equilibrium state is not necessarily a Gibbs state, but may be very well given by a Generalized Gibbs ensemble state. With this in mind, we develop a framework for studying entropy production and work extraction in closed quantum systems.
La termodinàmica va néixer com una teoria dedicada a l'estudi de cossos macroscòpics en equilibri tèrmic. A partir d'aquell moment, l'abast de la teoria no ha deixat d'augmentar, aplicant-se en l'actualitat a gran part de les disciplines científiques, així com a objectes de mides extremadament diferents. La present tesis està dedicada a l'estudi de la termodinàmica de sistemes quàntics. Conté resultats originals en diferents temes, que inclouen l'extracció de treball de sistemes quàntics, les fluctuacions de treball, la relació entre l'energia i les correlacions quàntiques, i la termodinàmica de sistemes de molts cossos. La primera part de la tesis està dedicada a l'estudi de l'extracció de treball de sistemes quàntics. En aquest context la noció d'estat passiu (un estat del qual no es pot extreure treball) és fonamental. Primer de tot, caracteritzem el conjunt d'estats passius, i en particular trobem els més energètics, que es troben a l'altre extrem dels estats tèrmics (o de Gibbs). Notablement, els estats passius poden ser activats, en el sentit que es pot extreure treball d'un conjunt suficientment gran de còpies d'un estat passiu. Estudiant en detall l'esmentat procés d'activació, trobem una relació entre la velocitat del procés i l'entrellaçament generat. Seguidament, considerem la possibilitat d'extreure treball d'un sistema utilitzant un bany tèrmic. En aquest cas, d'acord amb la segona llei de la termodinàmica, la quantitat de treball està limitada per l'energia lliure. Per sistemes quàntics, en molts casos no és possible extreure tota l'energia lliure, i desenvolupem correccions de la segona llei que depenen només de la mida del bany i de la seva estructura. A continuació estudiem les fluctuacions termodinàmiques (en particular del treball), que són especialment rellevants per sistemes microscòpics. La seva descripció en el règim quàntic és especialment difícil, donat que les mesures tenen un efecte invasiu en l'estat. De fet, mostrem que és impossible mesurar exactament les fluctuacions d'energia en processos que involucren coherència quàntica. Malgrat aquest resultat, també desenvolupem un sistema per mesurar les fluctuacions del treball de forma aproximada. Una part important d'aquesta tesis està dedicada a la relació entre les correlacions (quàntiques) i el treball. Comencem considerant un conjunt d'estats correlacionats, que individualment es troben en un estat tèrmic. La motivació és que en aquest cas el treball contingut en els estats prové únicament de les correlacions. En aquest escenari, calculem la quantitat de treball que es pot extreure d'estats entrellaçats, estats separables i estats correlacionats amb una determinada entropia. És a dir, calculem el treball màxim que es pot extreure de les correlacions, tan clàssiques com quàntiques. A continuació, considerem el procés invers, és a dir, la creació de correlacions en estats tèrmics. En aquest cas derivem límits en la temperatura màxima per poder crear diferents tipus entrellaçament, i el corresponent cost energètic. Finalment, estudiem la termodinàmica de sistemes de molts cossos. Aquí fem servir un dels resultats més importants relacionats amb l'equilibració en sistemes quàntics: sistemes quàntics tancats que involucren moltes partícules no arriben a l'equilibri, però es comporten com si hi haguessin arribat per la majoria d'observables (incloent observables rellevants des d'un punt de vista físic com l'energia). Tanmateix, el corresponent estat d'equilibri no és sempre tèrmic, i a vegades només es pot descriure mitjançant un estat generalitzat de Gibbs (GGE). La nostra contribució consisteix en desenvolupar un formalisme que permet estudiar la producció d'entropia i l'extracció del treball en estats GGE, el qual apliquem a sistemes de fermions.

Abstract (sommario):

This thesis explores the relationships between multifractal measures, multiplicative cascades and correlations. A review of fractal geometry, multifractal formalism and multiplicative cascades is offered. The importance of the Legendre transformation in multifractal formalism is highlighted, especially for multifractal spectrums which are not convex or twice differentiable. By reconsidering the scaling assumption $N sb{p}( alpha$) d$ alpha$ = $ sigma( alpha) rho sp{-f( alpha)} d alpha$, we show that subsets of a measure may offer a different multifractal spectrum. A gradation of self-similarity and scaling vis-a-vis canonicity is offered. Localized and generalized correlations are introduced, and two-point correlations are revisited for multiplicative cascades. A three-point correlation function is presented and discussed. The presence of an integral scale is shown to produce a more involved correlation scaling behaviour.

Abstract (sommario):

This thesis describes the preparation and characterisation of a number of tetrahalocuprate complexes. The compounds were made by reacting the chosen organic cation with the desired copper(II) salt. Three series of tetrahalocuprates were studied; (1) 5-amino-2-substituted pyridines, (2) mixed halide tetrahalocuprates using different dimethylpyridine isomers and (3) imidazolium ions. The structure of thirty three compounds were determined using single crystal X-ray crystallography. The compounds studied gave a wide range of different structures. The 5-amino-2-substituted pyridines showed four distinct structural types; (1) two isolated protonated pyridines and a single tetrahalocuprate anion, (2) unexpected bromine substitution on the pyridine rings, (3) Cu₃Cl chains with two pyridines bound to each terminal copper and (4) water bridged copper chloride chains for the iodo substituted pyridine. The mixed halide dimethylpyridine series illustrated the effects of varying the ratio of the halides in the tetrahalocuprate anions on the crystal packing of the compounds. A number of different structures for each isomer were studied. Attempts were made using a range of different imidazolium ions to form tetrahalocuprates. These ions would not require acid protonation and are unknown in the literature in this manner.

Abstract (sommario):

Abstract The aim of this work is to examine the state-of-the-art turbulent flame speed (ST) correlations and optimize their adjustable parameters to best match a wide range experimental turbulent premixed combustion results. Four correlations based on previous works by Zimont, Kobayashi, Ronney and Muppala have been selected for the present study. Using a Matlab-based Nelder-Mead simplex direct search method, each correlation’s adjustable parameters are optimized such that their mean absolute percentage error (MAPE) is minimized. In addition to the literature correlations, a new empirical correlation is developed using the same search method to define constants and powers in the expression. Two sets of optimized parameters are proposed to account for atmospheric and elevated (0.2–3.0 MPa) pressure flames. Each correlation is tested further, examining their ability to match ST trends for varying equivalence ratio (φ) and turbulent velocity ratio (u′/SL). It was found that a minimum of two correlations and two sets of adjustable parameters are required to accurately account for the entire range of data, thus showing that there is currently no turbulent flame speed correlation that is applicable across all engine-relevant conditions.

Abstract (sommario):

Abstract Empirically-based correlations are commonly used in modeling and simulation but rarely have rigorous uncertainty quantification that captures the nature of the underlying data. In many applications, a mathematical description for a parameter response to some input stimulus is often either unknown, unable to be measured, or both. Likewise, the data used to observe a parameter response is often noisy, and correlations are derived to approximate the bulk response. Practitioners frequently treat the chosen correlation — sometimes referred to as the “surrogate” or “reduced-order” model of the response — as a constant mathematical description of the relationship between input and output. This assumption, as with any model, is incorrect to some degree, and the uncertainty in the correlation can potentially have significant impacts on system responses. Thus, proper treatment of correlation uncertainty is necessary. In this paper, a method is proposed for high-level abstract sampling of uncertain data correlations. Whereas uncertainty characterization is often assigned to scalar values for direct sampling, functional uncertainty is not always straightforward. A systematic approach for sampling univariable uncertain correlations was developed to perform more rigorous uncertainty analyses and more reliably sample the correlation space. This procedure implements pseudo-random sampling of a correlation with a bounded input range to maintain the correlation form, to respect variable uncertainty across the range, and to ensure function continuity with respect to the input variable.

Abstract (sommario):

The objective of this project was to either validate the current correlations or develop a new correlation that are used to compare compressor maps. Most compressor maps are presented at standard temperature and pressure. In order to compare data that is not collected at these conditions, correlations are used to relate the data to standard conditions. This project analyzes the validity of currently used correlations and provides improved correlations as needed.

Abstract (sommario):

This study investigates the temporal and spatio-temporal correlations of solar power generation among different prosumers of Uppsala and Halmstad, Sweden. Using solar power generation data from seven prosumer in Uppsala and five in Halmstad, we evaluate the correlation of solar power production generation at specific locations correlates with itself over different time lags (autocorrelation). In addition, we examine the spatiotemporal correlations of solar power production at various locations over a range of lags using time shifted cross correlation. These spatio-temporal correlations can facilitate the development of synchronized demand response strategies and dynamic energy pricing. Moreover, the timeshifted cross-correlation analysis assists in improving forecasting models for solar power generation. By identifying significant correlations between solar generation data from different locations and applying time shifts to account for variations in weather and sunlight exposure, operators can enhance the accuracy of their predictions. This methodology enables them to fill in missing data points by leveraging correlated information from neighboring regions. Consequently, more robust forecasting models can be developed, leading to better resource allocation, improved energy management, and reduced operational uncertainties in the grid. This research highlights the evaluation and potential of utilizing spatio-temporal and temporal correlations in solar power data to enhance energy management and planning.
