Résumé
Abstract

Nous discutons les principaux résultats obtenus sur les propriétés universelles de la dynamique des interfaces élastiques en milieu aléatoire. Une attention particulière sera dédiée à la relation entre la géométrie rugueuse de lʼinterface en mouvement et ses proprietés de transport collectif. Les approches numériques développées permettent de décrire les propriétés dʼéquilibre, la dynamique de reptation et la transition de dépiégeage de lʼinterface. Nous discutons aussi la pertinence de nos résultats dans les expériences sur la dynamique des parois.

We discuss the universal dynamics of elastic interfaces in quenched random media. We focus on the relation between the rough geometry and collective transport properties in driven steady-states. Specially devised numerical algorithms allow us to analyze the equilibrium, creep, and depinning regimes of motion in minimal models. The relevance of our results for understanding domain wall experiments is outlined.
