Abstract:
This work investigated properties of diffusive magnetic particles. Random walk Monte Carlo method was used to simulate the Ising spin diffusing and flipping to examine the properties of the system. The Ising spins interact among themselves via Lennard-Jones interaction. Metropolis algorithm was employed to update spins configuration on the continuous space. The volume of Ising spins, magnetization and magnetic susceptibility, were investigated as functions of temperature, number of Ising spins in the system and simulation time. It was found that, at low temperatures, the Ising spins tend to stay close even at long simulation time, where finite magnetization was found suggesting the ferromagnetic preference. However, at high temperatures, paramagnetic behavior reveals as ferromagnetic interaction ceases with time passing. This is due to role of spin diffusing which causes the spins to disperse and hence ferromagnetic interaction among spins reduces.

Abstract:
We consider a model of discretized 2D gravity interacting with Ising spins where the phase boundaries are restricted to have minimal length and show analytically that the critical exponent, γ, is 1/3 at the spin transition point. The model captures the numerically observed behavior of standard multiple Ising spins coupled to 2D gravity.

Abstract:
A characteristic feature of the 3 d plaquette Ising model is its planar subsystem symmetry. The quantum version of this model has been shown to be related via a duality to the X-Cube model, which has been paradigmatic in the new and rapidly developing field of fractons. The relation between the 3 d plaquette Ising and the X-Cube model is similar to that between the 2 d quantum transverse spin Ising model and the Toric Code. Gauging the global symmetry in the case of the 2 d Ising model and considering the gauge invariant sector of the high temperature phase leads to the Toric Code, whereas gauging the subsystem symmetry of the 3 d quantum transverse spin plaquette Ising model leads to the X-Cube model. A non-standard dual formulation of the 3 d plaquette Ising model which utilises three flavours of spins has recently been discussed in the context of dualising the fracton-free sector of the X-Cube model. In this paper we investigate the classical spin version of this non-standard dual Hamiltonian and discuss its properties in relation to the more familiar Ashkin–Teller-like dual and further related dual formulations involving both link and vertex spins and non-Ising spins.

Abstract:
We study in this paper the resistivity encountered by Ising itinerant spins traveling in the so-called J1 - J2 frustrated simple cubic Ising lattice. For the lattice, we take into account the interactions between nearest-neighbors and next-nearest-neighbors, J1 and J2 respectively. Itinerant spins interact with lattice spins via a distance-dependent interaction. We also take into account an interaction between itinerant spins. The lattice is frustrated in a range of J2 in which we show that it undergoes a very strong first-order transition. Using Monte Carlo simulation, we calculate the resistivity ρ of the itinerant spins and show that the first-order transition of the lattice causes a discontinuity of ρ.

Abstract:
We present protocols for implementation of universal quantum gates on an arbitrary superposition of quantum states in a scalable solid-state Ising spin quantum computer. The spin chain is composed of identical spins 1/2 with the Ising interaction between the neighboring spins. The selective excitations of the spins are provided by the gradient of the external magnetic field. The protocols are built of rectangular radio-frequency pulses. Since the wavelength of the radio-frequency pulses is much larger than the distance between the spins, each pulse affects all spins in the chain and introduces the phase and probability errors, which occur even without the influence of the environment. These errors caused by the unwanted transitions are minimized and computed numerically.

Abstract:
The magnetic phase diagram of a dilute gas carrying an Ising spin variable and an electronic charge in two dimensions is investigated using a self consistent screening analysis. The bare interaction consists of a long range logarithmic potential which can be attractive (repulsive) for antiparallel (parallel) Ising spins and a screened Coulomb repulsion. The Ising Coulomb gas exhibits a real space pairing of antiparallel spins at low temperature and a plasma phase of free particles at high temperatures. The relevance of this model to pair formation in high temperature superconductors is discussed in the context of doped La 2 CuO 4.

Abstract:
Les verres de spins sont des matériaux magnétiques qui présentent à basse température un ensemble de propriétés inédites dont certaines sont caractéristiques de la combinaison du désordre et de contraintes conflictuelles. La modélisation aisée de tels systèmes magnétiques en vue d'un traitement analytique ou numérique a fait du verre de spins l'archétype des systèmes désordonnés. Toutefois, la complexité et l'étendue du savoir accumulé sur ces systèmes et les matériaux vitreux en général cachent une réalité frustrante: la compréhension de la physique qui les gouverne et la connaissance de la nature de leurs transitions de phase demeurent trop souvent incomplètes. Cette thèse repose sur l'étude numérique par simulation Monte-Carlo du comportement dynamique de modèles de verres de spins Ising et de leur transition de phase. L'analyse que nous faisons de l'ensemble de nos résultats et de ceux déjà existants dans la littérature se subdivise en trois parties en relation avec les objectifs que nous nous sommes fixés. Tout d'abord, explorer la validité de deux approches alternatives (le Damage spreadinq et la méthode des exposants effectifs) permettant l'étude du comportement critique des verres de spins et, ce faisant, faire apparaître la nécessité de prendre en compte les corrections aux lois d'échelles en taille finie à travers leurs effets sur les estimations des exposants critiques. Ensuite, utiliser cette panoplie de méthodes d'analyses alternatives pour poursuivre la construction d'un ensemble de preuves numériques en faveur d'une violation des règles d'Universalité pour les verres de spins Ising. Enfin, nous avons comparé les propriétés dynamiques de plusieurs modèles numériques avec des mesures expérimentales effectuées sur un ensemble de verres de polymères. L'existence d'une dynamique similaire pour ces systèmes très différents est interprétée en utilisant un scénario unique décrivant, dans l'espace des phases, la transition vitreuse comme une marche aléatoire sur un hypercube dilué<br>Spin glasses are magnetic materials that exhibit at low enough temperatures a number of unique properties, some of which arise from the combination of disorder and conflicting constraints. The ease with which one can modelize such systems for an analytic or numerical investigation has promoted spin glasses to the rank of archetype for disordered systems. However, the complexity and the extent of what is known on glassy materials hides a frustrating fact: the understanding of the physics that governs their behaviour and of the nature of glassy phase transitions often remains incomplete. This thesis is a study of the dynamical properties and phase transition of Ising spin glass models by means of Monte-Carlo simulations. The analysis of our results and of those taken from the literature falls into three parts and follows our main goals. First of all, to explore the validity of two alternative approaches (the Damage spreading and the effective exponent method) for the study of the critical behaviour of spin glass models and, in doing so, to point out the need to allow for corrections to finite size scaling by showing their effect on the determination of critical exponents. Secondly, using this array of alternative methods, to contribute to the ensemble of numerical evidences that indicate a violation of standard Universality rules in Ising spin glasses. Finally, to compare the dynamical properties of several Ising spin glasse models with experimental data on the dynamics of a range of glass forming polymers. The similarities observed in the dynamical behaviour of these very different systems is interpreted by using a unique scenario that describes glass-like transitions in phase space by means of a random walk on a diluted hypercube

A variational method based on Bogoliubov inequality for the free-energy has been employed. The trial Hamiltonians consist of clusters of free spins, pairs of spins, and a combination of free spins and pairs of spins. For the three approximations, the thermodynamic quantities of interest have been calculated, together with the critical transition temperature and the behavior close to the transition, in the latter case in order to compute the corresponding critical exponents. The results have been compared to each other as well with exact results, when available, or results coming from more reliable approximate methods. It has been noted that as more interactions are taken into account in the trial Hamiltonian, better results are obtained for the transition temperature, although the critical exponents are always the mean eld like ones.<br>Os modelos de Ising de spin-1=2 e spin-1, e o de Blume-Capel de spin-1 foram estudados em redes de uma, duas e três dimensões. Foi empregado o método variacional baseado na desigualdade de Bogoliubov para a energia livre. Os hamiltonianos tentativa utilizados consistem em blocos de spins livres, de pares de spins, e da combinacão de spins livres mais pares de spins. Para as três aproximacões, foram obtidas as quantidades termodinâmicas de interesse, bem como a temperatura crítica e o comportamento perto da transição, neste ultimo caso para se obter os respectivos expoentes críticos.

Consideramos, também, os estados de Gibbs para a representação do modelo de Potts com campo magnético invariante e não invariante por translação, e provamos uma versão da desigualdade FKG para o chamado modelo de aglomerados aleatórios geral (modelo GRC), com condição de fronteira livre e conectada no caso invariante e não invariante translacional.

We explicitly describe in terms of the random-cluster representation the distribution function and, consequently, the expected value of a single spin for the Ising and q-state Potts models with general external fields. We also consider the Gibbs states for the Edwards-Sokal representation of the Potts model with invariant and non-translation invariant magnetic field and prove a version of the FKG inequality for the so called general random-cluster model (GRC model) with free and wired boundary conditions in the invariant and non-translation invariant case. Adding the amenability hypothesis on the lattice, we obtain the uniqueness of the infinite connected component and the almost sure quasilocality of the Gibbs measures for the GRC model with such general magnetic fields. As a application of the theory developed, we show the uniqueness of the Gibbs measures for the ferromagnetic Ising model with a positive power-law decay magnetic field with small enough power, as conjectured in [23]. Finally we present a brief introduction and some results on Mallows distance giving some relationship with Gibbs measures presented previously.

Abstract:
La these traite les transitions de phase dans des systemes de spins avec interaction en competition par la simulation monte carlo (mc) avec la technique de l'histogramme. Les exposants critiques ont ete calcules a partir des lois d'echelle en taille finie. La premiere partie est consacree aux effets de la frustration dans le modele xy. L'etude des diagrammes de phase et la nature des transitions ont ete menees successivement sur le reseau triangulaire antiferromagnetique (3d), le reseau en damier (3d) et le reseau carre (2d). Parmi les resultats obtenus, on note, suivant le parametre de frustration, la mise en evidence des phases reentrantes paramagnetiques et des phases partiellement ordonnees pour le reseau en damier. Pour le modele xy completement frustre a 2d, la nature de la transition de phase a fait l'objet de plusieurs etudes analytiques et numeriques. Les resultats que nous avons obtenus montrent qu'il existe une seule transition contrairement au scenario qui prevoit deux transitions distinctes discute dans la litterature. De plus, les valeurs des exposants critiques, associes a la symetrie z 2, suggerent que la transition est dans le modele couple d'ising-xy. La deuxieme partie concerne un modele a spins d'ising sur des atomes en interaction elastique et magnetique. L'interet de ce modele est l'etude de l'effet du couplage magnetoelastique sur le comportement critique du systeme en fonction de l'intensite relative des forces magnetique et elastique. A forte interaction elastique, on retrouve la classe d'universalite d'ising, mais a faible interaction elastique, les calculs des histogrammes mc montrent que la transition est associee a des spins xy. Quand les interactions sont comparables, une nouvelle phase est obtenue, elle est due essentiellement a des contractions des paires de spins antiferromagnetiques.

Abstract:
Ce manuscrit présente l’étude expérimentale des propriétés structurales et physiques d’une série de composés à chaînes de spins Sr4−xCaxCoMn2O9, appartenant à la famille d’oxydes A1+X(A’XB1−X)O3. Dans cette série, les chaînes 1D sont constituées des octaèdres MnO6 et prismes trigonaux CoO6 reliés par les faces, et réparties sur un réseau triangulaire avec un couplage antiferromagnétique entre elles. Ces chaînes présentent une forte anisotropie magnétique de type Ising provenant du cation Co2+ (HS, 3d7, S = 3/2). D’abord, l'étude structurale de ces chaînes révèle qu’elles peuvent être incommensurables, à cause d’un changement de degré d'oxydation du cobalt en fonction des conditions de synthèse. Ensuite, nous nous sommes intéressés à l'étude des deux composés Sr4CoMn2O9 (x=0) et Sr2Ca2CoMn2O9 (x=2). Le composé x=0 commensurable a montré l'absence de mise en ordre magnétique à longue distance (LRO) et des réponses dynamiques de relaxation de spins, typiques des Single-Ion Magnet (SIM) et Single-Chain Magnet (SCM) dont l'amplitude de leurs pics caractéristiques dépendde la (in)commensurabilité. En revanche, dans x=2, seule la réponse SIM a été observée à basse température, et qui coexiste avec le LRO à TN ~ 28 K. Les données de diffraction des neutrons montrent que cet LRO est compatible avec un état antiferromagnétique partiellement désordonné (PDA). Un régime pré-transitionnel particulier a été aussi observé entre TN et T* (~ 32.5 K), qui a été considéré comme un effet précurseur de LRO. D'un autre côté, un couplage magnéto-électrique a été également mis en évidence au sein de ce composé, dont l'origine a été interprétée par un phénomène de striction d’échange. Finalement, nous avons étudié l'anisotropie magnétique dans des échantillons orientés, dont la morphologie des grains a été optimisée par différents traitements thermiques<br>This manuscript presents the experimental study of structural and physical properties of a spin chain compounds Sr4-xCaxCoMn2O9, belonging to the large oxides family A1+XA'XB1-XO3. In this series, the 1D chains are made up of the octahedra MnO6 (Mn4+) and trigonal prisms CoO6 (Co2+) connected by the faces, and distributed over a triangular lattice with an antiferromagnetic coupling between them. These chains exhibit a strong Ising-type magnetic anisotropy, originating from the cation Co2+ (HS, 3d7, S = 3/2). First of all, the structural study of these chains reveals that they can be immcommensurate, due to a change in the degree of oxidation of cobalt depending on the synthesis conditions. Then, we were interested in the study of the two compounds Sr4CoMn2O9 (x=0) and Sr2Ca2CoMn2O9 (x=2). The x=0 compound showed the absence of long-range magnetic ordering (LRO) and dynamic spin relaxation responses, typical of Single-Ion Magnet (SIM) and Single-Chain Magnet (SCM), of which the amplitude of their characteristic peaks depends on the (in)commensurability. On the other hand, in x = 2, only the SIM response was observed at low temperature, and which coexists with the LRO at TN ~ 28 K. The neutron diffraction data show that this LRO is compatible with a partially disordered antiferromagnetic state (PDA). A particular pre-transitional regime was also observed between TN and T* (~ 32.5 K), which was considered to be a precursor effect of LRO. Furthermore, a magneto-electric (ME) coupling has also been demonstrated within this compound. The mechanism of this ME coupling has been discussed as a result of exchange-striction phenomenon. Finally, we studied the magnetic anisotropy in oriented samples, whose grain morphology was optimized by different heat treatments

Abstract:
The thermodynamic properties of spin systems are evaluated with Monte Carlo methods. A review of classical thermodynamics is followed by a discussion of critical exponents. The Monte Carlo method is then applied to the two-dimensional Ising model with the goal of determining the phase diagram for magnetization. Boundary conditions, the reweighting method, autocorrelation, and critical slowing down are all explored. Cluster algorithms for overcoming critical slowing down are developed next and shown to dramatically reduce autocorrelation. A variety of spin systems that illustrate first, second, and infinite order (topological) phase transitions are explored. Finally, applications to random systems called spin glasses and to neural networks are briefly reviewed.
