RESUME-Les matériaux à transition de phase magnétostructurale présentent de forts couplages multiphysiques. Généralement, la transition est contrôlée par la température, ainsi que par des variables externes, comme la contrainte mécanique, o

In this thesis, we study phase transitions in random groups at density. A random group at density d is defined by a presentation with m generators and 2m-1 powers dl random relations, where l is the maximal length of the relations. We have two main r

Les matériaux de Dirac constituent une classe intéressante de systèmes pouvant subir une transition de phase quantique à température nulle, lorsqu’un paramètre non-thermique atteint un point critique quantique. À l’approche d’un tel poin

The forthcoming work is divided into two distinct parts. The first one deals with self-propelled particles systems. We start by studying the one particle in an external potential case. We derive the nonequilibrium properties of the Active Ornstein-Ul

This thesis investigates two polymer models that undergo an adsorption (or pinning) phase transition. The first model is a polymer interacting repulsively with its solvent and attractively with a hard wall. When solvent repulsion is sufficiently stro

The superconductor-insulator transition in two dimensions is a continuous quantum phase transition at absolute zero temperature driven by external parameters like disorder, magnetic field, or carrier concentration. Such transitions have been induced

This Thesis is devoted to the study of pinning models derived from the Poland-Scheraga model. The manuscript begins with a general presentation of the subject. This presentation has a dual purpose, as the manuscript aims to be read by two communities

Particle accelerators play a central role in the advancement of fundamental physics research. In circular accelerators such as the Large Hadron Collider (LHC) at CERN, the trajectory of the particle beams must be bent with magnetic fields. For this p
