Physique théorique

The aim of this lecture is to provide a description of quantum transport in disordered systems, with an emphasis on important phenomena like weak localization, Anderson localization and the Anderson metal-insulator transition. During the lecture, a number of important theoretical tools needed to describe quantum particle scattering in the presence of spatial disorder will be introduced in a pedagogical fashion, such as the Green's function technique, diagrammatic approaches to weak localization and transfer matrices. The lectures will be also illustrated by experimental examples and tutorials, especially taken from the physics of quantum gases and  condensed matter.

The goal of this course is to introduce the main concepts and challenges of quantum computing, a new set of technologies and techniques that promise to solve hard computational problems.

This course is an introduction to Conformal Field Theory (CFT), in the context of two-dimensional (and quantum 1d) critical phenomena. 

Dans le cadre de ce cours, nous allons étudier les interactions fondamentales de la physique des particules, décrites par le modèle standard, avec comme prérequis l’électromagnétisme élémentaire et la mécanique quantique.

Ce cours présente une introduction à la mécanique analytique. Loin de se cantonner à la mécanique, les principes variationnels sont présents dans tous les domaines de la physique (optique, hydrodynamique, mécanique quantique, etc...), ce que nous illustrerons lors des travaux dirigés.

Many physical systems exhibit phase transitions, i.e. abrupt changes in their properties when a parameter crosses a threshold value: a fluid changes from a liquid to a gaseous state at the evaporation temperature, a magnet loses its magnetic properties at the Curie temperature, and so on.
