Resumen
This paper proposes a specialized genetic algorithm (GA) based on an expended relational representation named weight-based encoding for solving one-dimensional bin packing problem (BPP-1). The encoding provides a totally constraint-handling scheme to address general and specific constraints, while naturally eliminates redundancy and infeasibility of previous representations for BPP-1. The current study performs experiments for solving some problem instances from a benchmark data set by our specific coded genetic algorithm with one-point, two-point and grouping crossovers. Experimental results show that the proposed methodology works well for solving BPP-1 and performs well on experimented benchmark instances. In addition, the results also show that two-point and grouping crossovers work better than one-point crossover in our experiments.

Resumen
In-plane ρ ab and out-of-plane ρ c resistivity measurements were performed on the same antiferromagnetic YBa 2 Cu 3 O 6.25 single crystal over a wide range of temperatures T. ρ ab (T) exhibits two crossovers with decreasing T: a crossover from metallic to weak localization behavior at 175 K and a second crossover to two-dimensional chiral variable-range hopping VRH behavior at 115 K. The latter reflects the topologic excitations induced in the spin system. ρ c (T) displays an [Formula: see text] dependence at high T and a VRH type dependence below 115 K. The T derivative of ρ c (T) shows a kink at 32.65 K which we attribute to the antiferromagnetic ordering of the Cu(1) spins.

Cataloged from PDF version of thesis.
Includes bibliographical references (pages 163-176).
Experiments using ultracold atomic gases address fundamental problems in many-body physics. This thesis describes experiments on strongly-interacting gases of fermionic atoms, with a focus on non-equilibrium physics and dimensionality. One of the fundamental dissipative processes in two-component gases is the transport of spin due to relative motion between the two spin components. We generate spin transport in strongly-interacting Fermi gases using a spin dipole excitation and measure the transport coefficients describing spin drag and spin diffusion. For resonant interactions, we observe strong suppression of spin transport, with the spin transport coefficients reaching quantum-mechanical limits. Dimensionality plays an important role in the formation of bound states between pairs of particles. We tune the dimensionality of a Fermi gas from three to two dimensions (2D) using an optical lattice potential and observe the evolution of the pair binding energy using radio-frequency spectroscopy. The binding energy increases as the lattice depth increases, approaching the 2D limit. Gases with resonant interactions, which have no two-body bound state in three dimensions, show a large binding energy determined by the confinement energy of the lattice wells. The themes of non-equilibrium dynamics and dimensionality come together in the study of soliton excitations in superfluid Fermi gases. We create a planar defect in the superfluid order parameter of an elongated Fermi gas using detuned laser light. This defect moves through the gas as a solitary wave, or soliton, without dispersing. We measure the oscillation period of the soliton and find it to exceed the predictions of mean-field theory by an order of magnitude.

Resumen
One of the most interesting and challenging problems in physics is understanding strongly correlated many-body systems, where strong interactions can yield many remarkable phenomena such as superfluidity in 4He, high-temperature superconductivity, etc. In order to attack these problems, we often need to reduce the complexity of the systems to simple models in hopes of getting better insights into the properties of the systems. The Hubbard model, the focus of this dissertation, is one of the most famous examples of such model, which describes a tunneling of electrons between nearest neighbor sites of a lattice with on-site interactions. This simple model is an important concept in condensed matter physics and provides rich understandings of electronic and magnetic properties of materials. Despite its simplicity, there is no general analytical solution to the Hubbard model beyond 1D.;The discovery of ultracold atoms and optical lattices opens up the possibility of emulating the Hubbard model in experiments. Optical lattices provide an ideal realization of the Hubbard model where relevant parameters can be tuned systematically. It makes theoretical studies of the Hubbard model increasingly attractive since a direct comparison between theoretical calculations and experimental results becomes more and more possible.;In this dissertation, the ground-state properties of the repulsive Hubbard model for weak to intermediate interaction strengths in two, three dimensions and their dimensional crossover are studied within the mean field theory. We show that the system exhibits unidirectional spin-density wave (SDW) order with antiferromagnetic correlations and a long wavelength modulation. The modulating wave is along the [0011-direction at low interaction strength U/t and along the [1111-direction at higher U/t. The evolution of the wavelength of the SDW is determined as a function of U/t, the density, and t⊥/t. With an analysis of the pairing of spins based on nesting and deformation of the Fermi surface, we discuss how these results can be rationalized and how a simple, predictive model can be constructed for the properties of the SDW states.

Resumen
Un des modèles théoriques les plus susceptibles d'expliquer le fonctionnement des supraconducteurs à haute température critique (SHTC) est le modèle de Hubbard . On comprend de plus en plus ce qui se passe en une dimension (1D) puisque sa solution est connue. Cependant, les calculs de chaleur spécifique montrent que la nature des excitations du modèle en 1D et en 2D (deux dimensions) n'est vraisemblablement pas la même dans les régimes dits de fort et faible couplage. On peut observer ce qui se passe entre les régimes 1D et 2D en introduisant un paramètre d'anisotropie variant continûment, soit: une intégrale de saut interchaîne t[indice]y , telle que 0 ? t[indice]y ? t[îndice]x ; t[indice]x représente ici l'intégrale de saut entre deux atomes voisins d'une même chaîne. On utilise ici la méthode Monte Carlo quantique développée par Blankenbecler, Scalapino et Sugar (MCQ) (BSS), combinée à une nouvelle technique de calcul de la chaleur spécifique dont l'idée de base est de calculer une dérivée aux différences finies en deux points assez peu éloignés l'un de l'autre, de telle sorte que l'on peut utiliser les mêmes configurations de champs de Hubbard-Stratonovich pour ces deux points et ainsi espérer réduire les effets des fluctuations statistiques. Si l'on se sert du nombre de bosses dans la chaleur spécifique comme critère pour discrimer les régime 1D et 2D (une bosse en 1D et deux bosses en 2D), on conclut que le crossover 1D-2D se situe entre t[indice]y ? 0.4t[indice]x et t[indice]y ? 0.6t[indice]x .

Resumen
L’exploration de systèmes quantiques à N corps fortement corrélés représente l’un des domaines de recherche les plus stimulants de la physique contemporaine. Au cours des trente dernières années, les vapeurs diluées d’atomes neutres en suspension dans le vide et contrôlées par un laser sont devenues une plate-forme polyvalente et formidable pour l’étude de tels systèmes. L’intérêt principal réside dans la capacité d’ajuster arbitrairement la force de l’interaction atomique au moyen de résonances de Feshbach induites magnétiquement, ainsi que la possibilité de créer une large gamme de potentiels via des champs optiques précisément adaptés. Cette thèse présente les résultats récents de l’expérience FerMix, consacrée à l’étude des systèmes quantiques à plusieurs corps fermioniques à des températures ultra-basses utilisant les atomes alcalins 40K et 6Li. Les principaux résultats présentés dans ce texte sont doubles. Premièrement, nous rapportons la caractérisation expérimentale d’une nouvelle résonance de Feshbach (s,d)-wave du 40K, dont les résultats sont comparés aux prédictions théoriques correspondantes. En particulier, le spectre du taux de perte inélastique est déterminé pour différentes températures et profondeurs de piège, ce qui nous permet d’identifier les pertes en tant que processus à deux corps. De plus, il est confirmé que le canal d’entrée dominant est de type s-wave. À l’aide de modèles d’équation de taux, nous analysons le réchauffement observé de l’ensemble atomique et trouvons que le comportement est cohérent avec l’état lié prévu L = 2 présent dans le canal de sortie. Enfin, nous étudions expérimentalement la dynamique des populations de spin induite par les collisions inélastiques renforcées par résonance dans l’onde d, en observant un bon accord avec nos modèles numériques. En second lieu, nous résumons nos progrès dans l’étude des croisements dimensionnels entre le liquide de Tomonaga-Luttinger en 1D et le liquide de Landau-Fermi en 3D en utilisant les gaz de Fermi de 40K confinés dans un réseau optique à grand pas. Cela inclut à la fois les considérations de conception fondamentales et l’installation du matériel expérimental requis
The exploration of strongly correlated quantum many-body systems represents one of the most challenging fields of research of contemporary physics. Over the past thirty years, dilute vapors of neutral atoms suspended in vacuum and controlled with laser light have become a versatile and powerful platform for the study of such systems. At the very heart lies the ability to arbitrarily tune the interaction strength by means of magnetically induced Feshbach resonances as well as the possibility to create a wide range of potential landscapes via precisely tailored optical fields. This thesis reports on the recent results of the FerMix experiment, which is dedicated to the study of fermionic quantum many-body-systems at ultralow temperatures using the Alkali atoms 40K and 6Li. The main results presented in this text are twofold. First, we report on the experimental characterization of a novel (s,d)-wave Feshbach resonance in 6Li, the results of which are compared to the corresponding theoretical predictions. In particular, the spectrum of the inelastic loss rate is determined for different temperatures and trap depths, which enables us to identify the losses as two-body processes. Moreover, the dominant entrance channel is confirmed to be s-wave in nature. Using rate equation models we analyze the observed heating of the atomic ensemble and find the behavior to be consistent with the predicted L = 2 bound state present in the exit channel. Finally, we investigate experimentally the dynamics of the spin populations driven by resonantly enhanced inelastic collisions in dwave, observing good agreement with our numerical models. Second, we summarize our progress towards the study of dimensional crossovers between the Tomonaga-Luttinger liquid in 1D and the Landau-Fermi liquid in 3D using Fermi gases of 40K confined in a large spacing optical lattice. This includes both the fundamental design considerations as well as the implementation of the required experimental hardware

Resumen
Abstract The following paper presents a modified crossover operator to extend the exploration capability in Genetic Algorithms for high dimensional optimization problems. Traditional strategies apply crossover once on a pair of selected chromosomes to generate two offspring by randomly selecting a single crossover location within the chromosomal length. The proposed method applies crossover once on each separate gene (variable) instead of on the entire chromosome. To further accelerate exploration of the Genetic Algorithm, nonuniform distribution of the respective crossover position on each gene has also been studied. The empirical results show that Genetic Algorithms with the proposed crossover strategies can find optimal or near optimal solutions within fewer generations than traditional single point crossover.

Resumen
A fully coupled three-dimensional, steady-state, two-fluid, multi-component and non-isothermal DMFC model has been developed in the commercial CFD package CFX 13 (ANSYS inc.). It accounts for the presence of micro porous layers, non-equilibrium phase change, and methanol and water uptake in the ionomer phase of the catalytic layer, and detailed membrane transport of methanol and water. In order to verify the models ability to predict methanol crossover, simulation results need to be compared with experimental measurements under different current densities along with air and methanol stoichiometries. Methanol crossover be indirectly measured based on the combined anode and cathode exhaust CO2 mole fraction and by accounting for the CO2 production at the anode as a function of current density. This approach is simple and assumes that all crossed over methanol is oxidized. Moreover, it takes CO2 crossover into account.
