Emergence of fermion-mediated interactions in Bose-Fermi mixtures
Esteban Cárdenas, Joseph K. Miller, David Mitrouskas +1
This work is inspired by recent experimental observations in ultracold atomic Bose-Fermi mixtures [DeSalvo et al., Nature 568 (2019)]. These experiments reveal the emergence of an…

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…

Derivation of a Boltzmann equation with higher-order collisions from a generalized Kac model
Esteban Cárdenas, Nataša Pavlović, William Warner
In this work, we generalize M. Kac's original many-particle binary stochastic model to derive a space homogeneous Boltzmann equation that includes a linear combination of higher-or…
