The renormalized Nelson model in the weak coupling limit
Esteban Cárdenas, David Mitrouskas
The Nelson model describes non-relativistic particles coupled to a relativistic Bose scalar field. In this article, we study the renormalized version of the Nelson model with massl…

Radiative corrections to the dynamics of a tracer particle coupled to a Bose scalar field
Esteban Cárdenas, David Mitrouskas
We consider a tracer particle coupled to a Bose scalar field and study the regime where the field's propagation speed approaches infinity. For initial states devoid of field excita…
