Eyring-Kramers asymptotics for infinite-dimensional stochastic gradient systems
Morris Brooks, Giacomo Di Gesù
We study small-noise asymptotics for a class of reversible stochastic evolution equations in infinite dimensions. The dynamics are of the form \[ dX_t=-A\nabla F(X_t)\,dt+\sqrt{2β…

Adiabatic Klein-Gordon Dynamics for the Renormalized Nelson Model
Morris Brooks, David Mitrouskas
We study the renormalized Nelson model in a semiclassical regime where the field becomes classical while the particle remains quantum. The degree of classicality is measured by a s…

Second order energy expansion of Bose gases with three-body interactions
Morris Brooks
We provide a second order energy expansion for a gas of bosonic particles with three-body interactions in the Gross-Pitaevskii regime. We especially confirm a conjecture by Nam…
