Abstract:

Taking into account both pinning and thermal fluctuation and employing the single flux flow model of Wang, Dong, and Ting (WDT), we have performed numerical study to investigate the flux motion in the weak pinning environment in the mixed-state of high-Tc superconductors. We find that there exist two kinds of weak pinning regime, one possesses low pinning concentration but strong individual pinning potentials, the other consists of high pinning concentration but weak individual pinning potentials for the double sign reversal of Hall resistivity ρxy. Moreover, our simulation and analysis suggest that the weak collective pinning effect may not be a good reason for the abnormal Hall effect. These results are well consistent with recent measurement of Bi2Sr2CaCu2O8 (BSCCO), Tl2Ba2CaCu2O8 (TBCCO) and HgBa2CaCu2O6 (HBCCO) and collective pinning theories for Hall effect.

Abstract:

We consider the (1+1) dimensional Laplacian model with pinning interaction. This is a probabilistic model for a polymer or an interface that is attracted to the zero line. Without the pinning interaction, the Laplacian model is a Gaussian field (Φi)iEΛN, where ΛN = {1, 2, ..., N - 1}. The covariance matrix of this field is given by the inverse of Φ -> 1/2 ENi=0(ΔΦi)2, where Δ is the discrete Laplacian. Furthermore the values at {-1, 0, N, N+1} are fixed boundary values. The pinning interaction is introduced by giving the field a reward each time it touches the zero line. Depending on the reward the model with pinning and the one without pinning show different behaviour. Caravenna and Deuschel [10] study the localisation behaviour of the polymer. The model is delocalised if the number of times a typical field touches the zero line is of order o(N). The authors of [10] show that for zero boundary conditions there is a critical reward such that for smaller rewards the model is delocalised whilst for larger rewards the model is localised. In this thesis we study the behaviour of the empirical profile of the field. We show that for non zero boundary conditions there is a critical reward such that for smaller rewards the empirical profile for the model with pinning and the one for the model without pinning behave in the same way whilst for larger rewards the empirical profile of the model with pinning interaction is attracted to the zero line.

Abstract:

Cette thèse se divise en deux parties indépendantes. La première (Chapitres 1 et 2) est consacrée à l’analyse de l’exposant de Lyapunov d’un produit de matrices de transfert aléatoires. Cet exposant de Lyapunov apparait de multiples fois dans la littérature physique, notamment dans l’analyse du modèle d’Ising dans certains milieux aléatoires. Nous nous intéressons à une prédiction de la littérature physique concernant son comportement singulier et nous proposons une analyse mathématique de cette singularité. La seconde partie (Chapitres 3, 4 et 5) porte sur une variation du modèle de Poland-Scheraga pour la dénaturation de l’ADN. Cette variation vise la prise en compte des contraintes géométriques particulières des chaines d’ADN circulaires. Nous analysons entièrement le modèle homogène: la régularité et le comportement critique de son énergie libre, ainsi que les trajectoires du polymère. Nous nous intéressons enfin au modèle désordonné, pour lequel nous établissons la pertinence du désordre, tant au niveau de l’énergie libre que des trajectoires du système<br>This work is made of two independent parts. The first (Chapters 1 and 2) is devoted to the study of the Lyapunov exponent of a product of random transfer matrices. This Lyapunov exponent appears repeatedly in the statistical mechanics literature, notably in the analysis of the Ising model in some special disordered environments. The focus is on a singular behaviour that has been pointed out in the physical literature: we provide a mathematical analysis of this singularity. In the second part (Chapters 3, 4 and 5) we consider a variation of the Poland-Scheraga model for DNA denaturation. This variation aims at modeling the case of circular DNA. We provide a complete analysis of the homogeneous model, including free energy regularity and critical behaviour, as well as path properties. We also tackle the disordered case, for which we prove relevance of disorder both for the free energy and the trajectories of the system

Abstract:

The study of supercooled liquids and glasses remains one of the most divisive and divided fields in modern physics. Despite a vast amount of effort and research time invested in this topic, the answers to many central questions remain disputed and incomplete. However, the link between the behaviour of supercooled liquids and their energy landscapes is well established and widely accepted. Understanding this link would be a key step towards resolving many of the mysteries and controversies surrounding the glass transition. Therefore the study of glassy energy landscapes is an important area of research. In this thesis, I report some of the most detailed computational studies of glassy potential energy landscapes ever performed. Using geometry optimisation techniques, I have sampled the local minima and saddle points of the landscapes for several supercooled liquids to analyse their dynamics and thermodynamics. Some of my analysis follows previous work on the binary Lennard-Jones fluid (BLJ), a model atomic liquid. BLJ is a fragile glass former, meaning that its transport coefficients have super-Arrhenius temperature dependence, rather than the more usual Arrhenius behaviour exhibited by strong liquids. The difference in behaviour between these two classes of liquid has previously been attributed to differing degrees of structure in the relevant energy landscapes. I have studied models for both fragile and strong glass formers: the molecular liquid ortho-terphenyl (OTP) and viscous silica (SiO$_{2}$) respectively. My results for OTP agree closely with trends observed for BLJ, suggesting that the same diffusion mechanism is applicable to fragile molecular liquids as well as to atomic. However, the dynamics and energy landscape of OTP are made complicated by the molecular orientational degrees of freedom, making the analysis more challenging for this system. Dynamics of BLJ, OTP and silica are all dominated by cage-breaking events: structural rearrangements in which atoms change their nearest neighbours. I propose a robust and general method to identify cage breaks for small rigid molecules, and compare some properties of cage breaks between strong and fragile systems. The energy landscapes of BLJ and OTP both display hierarchical ordering of potential energy minima into metabasins. These metabasins can be detected by the cage-breaking method. It has previously been suggested that metabasins are responsible for super-Arrhenius behaviour, and are absent from the landscapes of strong liquids such as SiO2. My results indicate that metabasins are present on the silica landscape, but that they each contain fewer minima than metabasins in BLJ or OTP. Metabasins are associated with anticorrelated particle motion, mediated by reversed transitions between minima of the potential energy landscape. I show that accounting for time-correlation of particle displacement vectors is essential to describe super-Arrhenius behaviour in BLJ and OTP, but also required to reproduce strong behaviour in silica. I hypothesise that the difference between strong and fragile liquids arises from a longer correlation timescale in the latter case, and I suggest a number of ways in which this proposition could be tested. I have investigated the effect on the landscape of freezing the positions of some particles in a BLJ fluid. This “pinning” procedure induces a dynamical crossover that has been described as an equilibrium “pinning transition”, related to the hypothetical ideal glass transition. I show that the pinning transition is related to (and probably caused by) a dramatic change in the potential energy landscape. Pinning a large fraction of the particles in a supercooled liquid causes its energy landscape to acquire global structure and hence structure-seeking behaviour, very different from the landscape of a typical supercooled liquid. I provide a detailed description of this change in structure, and investigate the mechanism underlying it. I introduce a new algorithm for identifying hierarchical organisation of a landsape, which uses concepts related to the pinning transition but is applicable to unpinned liquids as well. This definition is complementary to metabasins, but the two methods often identify the same higher-order structures. The new “packings” algorithm offers a route to test thermodynamic theories of the glass transition in the context of the potential energy landscape. Over the course of this thesis, I discuss several different terms and methods to identify higher-order structures in the landscapes of model glass formers, and investigate how this organisation varies between different systems. Although little variation is immediately apparent between most glassy landscapes, deeper analysis reveals a surprising diversity, which has important implications for dynamical behaviour in the vicinity of the glass transition.

Abstract:

Le modèle de Poland-Scheraga (PS) est le modèle standard pour étudier la transition de dénaturation de deux brins d’ADN complémentaires et de même longueur. Ce modèle a fait l’objet d’une attention remarquable car il est exactement résoluble dans sa version homogène. Le caractère résoluble est lié au fait que le modèle PS homogène peut être mis en correspondance avec un processus de renouvellement discret. Dans la littérature biophysique une généralisation du modèle, obtenue en considérant des brins non complé- mentaires et de longueurs différentes, a été considérée et le caractère résoluble s’étend à cette généralisation substantielle. Dans cette thèse, nous présentons une analyse mathématique du modèle de Poland- Scheraga généralisé. Nous considérons d’abord le modèle homogène et nous exploitons que les deux brins de la chaîne peuvent être modélisés par un processus de renouvellement en deux dimensions. La distribution K(⋅) de l’emplacement (bidimensionnel) du premier contact entre les deux brins est supposée de la forme K(n+m) = (n+m)−α−2L(n+m) avec α ≥ 0 et L(⋅) à variation lente et correspond à une boucle avec n bases dans le premier brin et m dans le deuxième. Nous étudions la transition de localisation-délocalisation et nous montrons l’existence des transitions à l’intérieur de la phase localisée. Nous présentons ensuite des estimations précises sur les propriétés de chemin du modèle. Ensuite, nous étudions la version désordonnée du modèle en incluant une séquence de variables aléatoires indépendantes identiquement distribuées à deux indices. Nous nous concentrons sur l’influence du désordre sur la transition de dénaturation: nous voulons déterminer si la présence des inhomogénéités modifie les propriétés critiques du système par rapport au cas homogène. Nous prouvons que le désordre est non pertinent si α < 1 et nous montrons que pour α > 1, les points critiques gelés et recuits diffèrent (basant sur les techniques de coarse graining et la méthode des moments fractionnaires), ce qui prouve la présence d’un régime de désordre pertinent<br>The Poland-Scheraga (PS) model is the standard basic model to study the denaturation transition of two complementary and equally long strands of DNA. This model has enjoyed a remarkable attention because it is exactly solvable in its homogeneous version. The solvable character is related to the fact that the homogeneous PS model can be mapped to a discrete renewal process. In the bio-physical literature a generalization of the model, allowing different length and non complementarity of the strands, has been considered and the solvable character extends to this substantial generalization. In this thesis we present a generalized version of the PS model that allows mismatches and non complementary strands (in particular, the two strands may be of different lengths). We consider first the homogeneous model and we exploit that this model can be mapped to a bivariate renewal process. The distribution K(⋅) of the location (in two dimensions) of the first contact between the two strands is assumed to be of the form K(n + m) = (n + m)−α−2L(n + m) with α ≥ 0 and L(⋅) slowly varying and corresponds to a loop with n bases in the first strand and m in the second. We study the localization-delocalization transition and we prove the existence of transitions inside the localized regime. We then present precise estimates on the path properties of the model. We then study the disordered version of the model by including a sequence of inde- pendent and identically distributed random variables with two indices. We focus on the influence of disorder on the denaturation transition: we want to determine whether the presence of randomness modifies the critical properties of the system with respect to the homogeneous case. We prove that the disorder is irrelevant if α < 1. We show also that for α > 1, the quenched and annealed critical points differ (basing on coarse graining techniques and fractional moment method), proving the presence of a relevant disorder regime

Abstract:

Ce memoire est une contribution a la phenomenologie des supraconducteurs anisotropes et lamellaires, et comporte trois grandes parties. Dans la premiere de ces parties, nous avons calcule la barriere d'ancrage intrinseque dans un supraconducteur lamellaire, dans le regime quasi-3d du modele de lawrence-doniach ou la longueur de coherence dans la direction transversale aux plans supraconducteurs devient superieure a la distance entre ces derniers. On montre alors que grace a la structure specifique du cur d'un vortex parallele aux plans supraconducteurs, l'ancrage intrinseque peut etre observe jusqu'a des temperatures proches de la temperature critique. Le resultat de cette etude est ensuite utilise pour completer la theorie de feinberg-villard de la transition de verrouillage et formuler ainsi un modele phenomenologique valable aussi bien aux basses temperatures que pres de la temperature critique. Le deuxieme volet de ce travail concerne l'ancrage des vortex par des defauts colonnaires paralleles a l'axe de symetrie du crystal. Nous montrons en particulier que ces defauts peuvent donner lieu dans une certaine region du diagramme de phase (h,t) a une nouvelle structure ou le reseau de vortex est constitue de deux sous-reseaux perpendiculaires orientes suivant les deux directions de symetrie du crystal. La derniere partie de ce travail est consacree a l'etude d'un modele phenomenologique qui generalise le modele de lawrence-doniach en tenant compte de l'existence eventuelle d'effets de proximite entre les feuillets supraconducteurs et les couches intercalaires dans un materiau lamellaire. Nous montrons alors que l'anisotropie effective d'un supraconducteur lamellaire a effet de proximite depend du champ magnetique applique et de la temperature et est generalement differente de l'anisotropie donnee par le rapport des champs critiques parallele et perpendiculaire aux feuillets supraconducteurs

Abstract:

Cette thèse porte sur l'étude de modèles de polymère en milieu aléatoire: on se concentre sur le cas d'un polymère dirigé en dimension d+1 qui interagit avec un défaut unidimensionnel. Les interactions sont possiblement non-homogènes, et sont représentées par des variables aléatoires. Une question importante est celle de l'influence du désordre sur le phénomène de localisation: on veut déterminer si la présence d'inhomogénéités modifie les propriétés critiques du système, et notamment les caractéristiques de la transition de phase (auquel cas le désodre est dit pertinent). En particulier, nous prouvons que dans le cas où le défaut est une marche aléatoire, le désordre est pertinent en dimension d≥3. Ensuite, nous étudions le modèle d'accrochage sur une ligne de défauts possédant des inhomogénéités corrélées spatialement. Il existe un critère non rigoureux (dû à Weinrib et Halperin), que l'on applique à notre modèle, et qui prédit si le désordre est pertinent ou non en fonction de l'exposant critique du système homogène, noté νpur, et de l'exposant de décroissance des corrélations. Si le désordre est gaussien et les corrélations sommables, nous montrons la validité du critère de Weinrib-Halperin: nous le prouvons dans la version hiérarchique du modèle, et aussi, de manière partielle, dans le cadre (standard) non-hiérarchique. Nous avons de plus obtenu un résultat surprenant: lorsque les corrélations sont suffisamment fortes, et en particulier si elles sont non-sommables (dans le cadre gaussien), il apparaît un régime où le désordre devient toujours pertinent, l'ordre de la transition de phase étant toujours plus grand que νpur. La prédiction de Weinrib-Halperin ne s'applique alors pas à notre modèle.

Abstract:

Le modèle d'accrochage de polymère décrit le comportement d'une chaîne de Markov en interaction avec un état donné. Cette interaction peut attirer ou repousser la chaîne de Markov et elle est modulée par deux paramètres, h et β. Quand β = 0 on parle de modèle homogène, qui est complètement solvable. Le modèle désordonné, i.e. quand β > 0, est mathématiquement le plus intéressant. Dans ce cas, l'interaction dépend d'une source d'aléa extérieur indépendant de la chaîne de Markov, appelée désordre. L'interaction est réalisée en modifiant la loi originelle de la chaîne de Markov par une mesure de Gibbs et la probabilité obtenue définit le modèle d'accrochage de polymère. Le but principal est d'étudier et de comprendre la structure des trajectoires typiques de la chaîne de Markov sous cette nouvelle probabilité. Le premier sujet de recherche concerne le modèle d'accrochage de polymère où le désordre est à queues lourdes et où le temps de retour de la chaîne de Markov suit une distribution sous-exponentielle. Dans notre deuxième résultat nous étudions le modèle d'accrochage de polymère avec un désordre à queues légères et le temps de retour de la chaîne de Markov avec une distribution à queues polynomiales d'exposant α > 0. On peut démontrer qu'il existe un point critique, h(β). Notre but est comprendre le comportement du point critique quand β -> 0. La réponse dépend de la valeur de α. Dans la littérature on a des résultats précis pour α < ½ et α > 1. Nous montrons que α ∈ (1/2, 1) le comportement du modèle dans la limite du désordre faible est universel et le point critique, opportunément changé d'échelle, converge vers la même quantité donnée par un modèle continu<br>The pinning model describes the behavior of a Markov chain in interaction with a distinguished state. This interaction can attract or repel the Markov chain path with a force tuned by two parameters, h and β. If β = 0 we obtain the homogeneous pinning model, which is completely solvable. The disordered pinning model, i.e. when β > 0, is most challenging and mathematically interesting. In this case the interaction depends on an external source of randomness, independent of the Markov chain, called disorder. The interaction is realized by perturbing the original Markov chain law via a Gibbs measure, which defines the Pinning Model. Our main aim is to understand the structure of a typical Markov chain path under this new probability measure. The first research topic of this thesis is the pinning model in which the disorder is heavy-tailed and the return times of the Markov chain have a sub-exponential distribution. In our second result we consider a pinning model with a light-tailed disorder and the return times of the Markov chain with a polynomial tail distribution, with exponent α > 0. It is possible to show that there exists a critical point, h(β). Our goal is to understand the behavior of the critical point when β -> 0. The answer depends on the value of α and in the literature there are precise results only for the case α < ½ et α > 1. We show that for α ∈ (1/2, 1) the behavior of the pinning model in the weak disorder limit is universal and the critical point, suitably rescaled, converges to the related quantity of a continuum model

Cette thèse est consacrée à l’étude du modèle d’accrochage en environnementfaiblement corrélé. Le modèle d’accrochage s’applique à de multiples situationstelles que la localisation d’un polymère au voisinage d’une interface unidimensionnelle,la transition de mouillage ou encore la dénaturation de l’ADN, le pointcommun étant la présence d’une transition entre une phase localisée et une phasedélocalisée.Nous commençons par donner un aperçu des résultats disponibles sur lescourbes et exposants critiques pour le modèle homogène puis pour le modèledésordonné lorsque le désordre est une suite de variables aléatoires indépendanteset identiquement distribuées (i.i.d.). Dans ce dernier cas, nous donnons égalementune borne sur la courbe critique quenched à haute température, dans un régimeoù le désordre est dit pertinent.Nous étudions ensuite le modèle d’accrochage désordonné dans le cas où ledésordre est gaussien et les corrélations ont une portée finie, à l’aide de la théoriedes processus de renouvellement markoviens.

In the latter case, we also provide a hightemperaturebound on the quenched critical curve in a case of relevant disorder.We then study the random pinning model when disorder is gaussian and hascorrelations with finite range, using the theory of Markov renewal processes. Weexpress the annealed critical curve in terms of the largest eigenvalue of a transfermatrix and we give the annealed critical exponent. We then generalize the criteriafor disorder relevance/irrelevance that were proved for the i.i.d. case.Next we are interested in disorder sequences with infinite range correlations.At first we generalize the method used to deal with finite range correlations andobtain the annealed critical behaviour in the case of gaussian disorder assumingfast decay of correlations. We use to this end the spectral properties of transferoperators for shifts on integer sequences and potentials with summable variations.Secondly we provide some results when disorder is a Markov chain

Abstract:

Ferromagnetic shape memory alloys in the Ni-Mn-Ga system exhibit large reversible deformations of up to 9.5% in response to magnetic fields. Prior experimental measurements by the authors demonstrated large reversible strains of −0.41% along the [001] crystal direction of a cylindrical Ni50Mn28.7Ga21.3 rod driven with a magnetic field along the same direction and no external restoring force. This represents an unusual configuration which can lead to solenoid transducers with enhanced energy density and bandwidth relative to standard electromagnet devices. The paper builds on a previous thermodynamic framework which accurately quantifies several reversible and irreversible effects in the polarization of ferroic materials. The switching between two variant orientations in the presence of Zeeman energy and pinning energy is formulated through a Gibbs energy functional for the crystal lattice. The presence of nonhomogeneous local interaction fields, nonhomogeneous pinning distributions, and complex crystallographic features in real Ni-Mn-Ga alloys is addressed through stochastic homogenization techniques. Attributes of the model are illustrated through comparison of model results with experimental data.

Abstract:

We carried out drying studies on a 2.5D micromodel based on a thin section of a carbonate rock to investigate the impact of wettability on the capillary disconnect, the moment when liquid films de-pin from the external evaporating surface. While this is coincident with the transition to low evaporation rate (diffusion limited) for deionized-water, our experiments show, the corner wetting films persisted after the transition to low evaporation rate for both water-wet and mixed-wet micromodels for brine, as solid salt continued to build up at the external evaporating surface. Fully oil wet micromodels showed a drying rate transition coincident with de-pinning. Keywords: Capillary; Liquid films; Micromodel; Wettability; Crystallization
