Long-time propagation of chaos and exit times for metastable mean-field particle systems
Pierre Monmarché
Systems of stochastic particles evolving in a multi-well energy landscape and attracted to their barycenter is the prototypical example of mean-field process undergoing phase trans…

Uniform convergence of the Fleming-Viot process in a hard killing metastable case
Lucas Journel, Pierre Monmarché
We study the long-time convergence of a Fleming-Viot process, in the case where the underlying process is a metastable diffusion killed when it reaches some level set. Through a co…
