Colloquium du Ceremade (Guillaume Barraquand, mardi 4 novembre 2025)

20 octobre 25

Le prochain Colloquium du Ceremade est prévu le mardi 4 novembre à 15h30 en salle A709 avec l'intervention de Guillaume Barraquand (ENS Paris) sur le sujet suivant :


Extreme diffusion

Abstract 
Diffusion phenomena are ubiquitous in nature and have been studied theoretically for more than a century. Still, the influence of a random environment on diffusion is not very well understood. I will discuss about the simplest possible model of diffusion in random environment: a simple random walk. We will see that using methods coming from integrable systems, one can relate the extreme statistics of diffusive particles in random environment to an area of Statistical Physics called the Kardar-Parisi-Zhang universality class.
