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…
