Texto completoThis thesis explores diverse topics related to hyperbolic geometry and group dynamics, aiming to investigate the interplay between geometry and group theory. It covers a wide range of mathematical disciplines, such as convex geometry, stochastic analysis, ergodic and geometric group theory, and low-dimensional topology, etc. As research outcomes, the hyperbolic geometry of infinite-dimensional convex bodies is thoroughly examined, and attempts are made to develop integral geometry in infinite dimensions from a perspective of stochastic analysis. The study of big mapping class groups, a current focus in low-dimensional topology and geometric group theory, is undertaken with a complete determination of their fixed-point on compacta property. The thesis also clarifies certain folklore theorems regarding the Gromov hyperbolic spaces and the dynamics of amenable groups on them. Last but not the least, the thesis studies the connectivity of the Gromov boundary of fine curve graphs, a combinatorial tool employed in the study of the homeomorphism groups of surfaces of finite type

Texto completoTopology is the area of mathematics investigating the qualitative properties of shapes and spaces. Although it has been a classical field of study for more than a century, it only appeared recently that being able to compute the topological features of various spaces might be of great value for many applications. This idea forms the core of the blossoming field of computational topology, to which this work belongs. The three contributions of this thesis deal with the development and the study of topological algorithms to compute deformations and decompositions of low-dimensional objects, such as graphs, surfaces or 3-manifolds. The first question we tackle concerns deformations: how can one test whether two graphs embedded on the same surface are isotopic, i. E. , whether one can be deformed continuously into the other? This kind of problems is relevant to practical problems arising with morphings or geographic information systems, for example. Relying on hyperbolic geometry and ideas from the theory of mapping class groups, we first establish a combinatorial criterion to characterize isotopy, reproving and strengthening a result of Ladegaillerie (1984). Combined with earlier algorithms on the homotopy of curves, this allows us in turn to provide efficient algorithms to solve this graph isotopy problem. We then shift our focus to decompositions, by investigating how to cut surfaces along curves or graphs with prescribed topological properties, which is an important routine in graph algorithms or computer graphics, amongst others domains. By establishing a strong connection with the continuous setting, as well as studying a discrete model for random surfaces, we improve the best known bounds for several instances of this problem. In particular, this proves a conjecture of Przytycka and Przytycki from 1993, and one of our new bounds readily translates into an algorithm to compute short pants decompositions. Finally, we move up one dimension, where the best known algorithms for many topological problems, like for example unknot recognition, are exponential. Most of these algorithms rely on normal surfaces, a ubiquitous tool to study the surfaces embedded in a 3-manifold. We investigate a relaxation of this notion called immersed normal surfaces, whose more convenient algebraic structure makes them good candidates to solve topological problems in polynomial time. We show that when working with immersed normal surfaces, a natural problem on the detection of singularities arises, and we prove it to be NP-hard – this is noteworthy as hardness results are very scarce in 3-dimensional topology. Our reduction works by establishing a connection with a restricted class of constraint satisfaction problems which has been partially classified by Feder

Texto completoThis thesis focuses on the study of a chromium oxide family in which the samples are synthsized into two forms with two different topologies : α-ACr₂O₄ (A=Sr, Ca, Ba) and β-CaCr₂O₄. In these compounds, the chromium ions carry a spin 3/2 and either form triangular spin chains or two dimensional triangular lattices. Our study was hence divided in two parts : the study of a quasi one-dimensional and of a two-dimensional antiferromagnet.The first part was dedicated to the β-CaCr₂O₄ compound. This system exhibits a classical behavior at low temperature associated to a three-dimensional long-range magnetic order and quantum properties typical of a spin chain above the Néel temperature.The aim o four study was therefore to understand the mecanism involved in this classical to quantum physics crossover.In this context, we explored the topological and structural effects on the magnetic properties of this system, through the study of the series of substituted compounds β-CaCr₂-xScxO₄, as well as a study of β-CaCr₂O₄ under pressure. This work was also supported by theoretical calculations on frustrated J₁-J₂ spin chains.The second part of this thesis focused on α-SrCr₂O₄. In particular, neutron scattering measurements on this compound highlighted the effects of the 2D character and the distortion of the triangular lattice on the ground state and dynamical properties in this system

Texto completoThis thesis presents original results in two domains of disordered statistical physics: logarithmic correlated Random Energy Models (logREMs), and localization transition in long-range random matrices.In the first part devoted to logREMs, we show how to characterise their common properties and model--specific data. Then we develop their replica symmetry breaking treatment, which leads to the freezing scenario of their free energy distribution and the general description of their minima process, in terms of decorated Poisson point process. We also report a series of new applications of the Jack polynomials in the exact predictions of some observables in the circular model and its variants. Finally, we present the recent progress on the exact connection between logREMs and the Liouville conformal field theory.The goal of the second part is to introduce and study a new class of banded random matrices, the broadly distributed class, which is characterid an effective sparseness. We will first study a specific model of the class, the Beta Banded random matrices, inspired by an exact mapping to a recently studied statistical model of long--range first--passage percolation/epidemics dynamics. Using analytical arguments based on the mapping and numerics, we show the existence of localisation transitions with mobility edges in the ``stretch--exponential'' parameter--regime of the statistical models. Then, using a block--diagonalization renormalization approach, we argue that such localization transitions occur generically in the broadly distributed class

Texto completoFrom a topological point of vien this work deals with the structure of a set of affine and controllable systems. From the work of (J. S. ), (A. S. V. ) it appeared that definite relations exist between topological structure of a set of affine controllable systems Ca and Ch. In particuler the properties of Fr Ca and the connexivy of Ca arise direcly from analogouds properties of Ch. We show that Ca gives rise to two types of boundary points. We can expect to have three types of boundary points. The interior of the closed set Ca contains affine controllable systems for which the trajectories are cycles. For the other cases they are on the exterior boundaries, we also show that the interior of Ca is uniquely composed of (J. S. ) and affine controllable systems to which correspond homogeneous non-controllable systems characterized by collinear fields (non-independent spirals). Our result is that the set of affine controllable systems Ca is connected

Texto completoThis thesis deals with the physics of magnetic systems in an external field and when frustration, arising either from the geometry or from competing interations, is present. We have studied several models in low dimensions, where the effects of the quantum fluctuations are more important and can lead to the apparition of new intersting quantum phases. This manuscript is divided in three parts, each one being dedicated to a given model. In the first two parts, we consider two one-dimensional spin tube models, respectively made of three and four coupled spin chains, that we study by using various analytical and numerical methods. We show that, beyond the appearance of magnetization plateaux, a rich physics can emerge, with the role of the non magnetic modes for the first model, or, in the second case, the consequences of a continuous degeneracy at the classical level on the quantum phase diagram. In the third part, we use numerical Quantum Monte-Carlo simulations to study an anisotropic spin model on the two-dimensional Kagomé lattice, designed for the search of topological phases. We obtain the phase diagram on one of the magnetization plateaux of this model, and use this example to discuss the relevance of the computation of the entanglement entropies in order to identify phases in numerical simulations

Texto completoA good number of physical systems may be modelled by quantum particles on a lattice. Strongly correlated systems in one and two dimensions are particularly interesting because of the enhanced quantum effects not well described by mean field. In addition there is growing number of real materials which are truly one or two dimensional such as helium adsorbed on graphite, high temperature superconductors and Bose-Einstein condensates on optical lattices to mention only a few. These systems are well described by the lattice Hubbard model which, by virtue of being on a lattice, is amenable to precision numerical simulations which don’t suffer from the many approximations needed in the analytical calculations. In this thesis we apply the Hubbard model to study some systems which are currently of high theoretical and experimental interest

Texto completoLow-dimensional oxides with disconnected magnetic units are of increasing interest due the peculiar properties and the versatile interplay between individual magnetic moments into an external magnetic field: metamagnetic transition, magnetization steps…. In addition to understanding these phenomena, the importance of this type of compounds is also emerging properties indirectly related to the specific magnetization of these systems that can be part of the field of "spintronic". Our work, upstream, is the synthesis and study of new compounds, mainly low dimensional oxides, which bring a new vision on such properties, due to their particular magnetic behaviors. The aim of this thesis was therefore to prepare and characterize novel compounds, but also to solve the structure-properties relationship. The results obtained through a work of reflected synthesis, have identified chemical systems favorable to the realization of low-dimensional magnetic materials. Several new phases with specific properties have been identified. It is clear that all the observed behaviors: 2D Ising-FM, SCM, magnetization step, reversible extrusion are relatively original and have led to important advances in the understanding of magnetism of weakly interacting subunits
