The objective of this thesis is the study of rare dynamical events in some interacting particle systems. Two models are considered : the one dimensional symmetric simple exclusion process interacting with reservoirs, and an interface dynamics related

The aim of this thesis is the study of some important problems in credit risk, namely the monotony of transition matrices and interdependence in credit portfolios. On the first topic, we provide a new way to idealise completely and optimally empirica

This thesis deals with the existence of Gaussian concentration for sufficiently mixing equilibrium states for lattice systems. Moreover, we show that such a property ensures uniqueness.In the first chapter, we show that if an equilibrium state associ

Many models in physics present a phenomenon called phase transition: there is a critical point or a critical curve in the parameter space separating two distinct regions characterized by very different macroscopic properties. In such systems, the beh

This thesis examines the properties of the interface between two phases in phase separated systems. We are interested in how finite size effects modify the statistical properties of these interfaces, in particular how the dependence of the free energ

Les interfaces dans les modèles de percolation et d'Ising jouent un rôle crucial dans la compréhension de ces modèles et sont au coeur de plusieurs problématiques : la construction de Wulff, le mouvement par courbure moyenne, la théorie du SLE.

Lupu introduced a coupling between a random walk loop-soup and a Gaussian free field, where the sign of the field is constant on each cluster of loops. This coupling is a signed version of isomorphism theorems relating the square of the GFF to the oc

Les méthodes de Monte Carlo par chaines de Markov MCMC sont des outils mathématiques utilisés pour simuler des mesures de probabilités π définies sur des espaces de grandes dimensions. Une des questions les plus importantes dans ce contexte est

Quentin Rodriguez discusses the nature of standard explanations of the universality of critical phenomena: how do they differ from other physical explanations using mathematical models (ideal gas model, harmonic oscillator model)? In what way can the
