Metastable transitions in inertial Langevin systems: what can be different from the overdamped case?
Andre Souza, Molei Tao
Metastable transitions in Langevin dynamics can exhibit rich behaviors that are markedly different from its overdamped limit. In addition to local alterations of the transition pat…

Temperature and Friction Accelerated Sampling of Boltzmann-Gibbs Distribution
Molei Tao, Houman Owhadi, Jerrold E. Marsden
This paper is concerned with tuning friction and temperature in Langevin dynamics for fast sampling from the canonical ensemble. We show that near-optimal acceleration is achieved…
