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…
Bound excited states of Fröhlich polarons in one dimension
Jamie Taylor, Matija Äufar, David Mitrouskas +3
The one-dimensional Fröhlich model describing the motion of a single electron interacting with optical phonons is a paradigmatic model of quantum many-body physics. We predict the…
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…
Derivation of the time-dependent Hartree equations for strongly interacting dense fermionic systems
Duc Viet Hoang, David Mitrouskas, Peter Pickl
The time-dependent Hartree and Hartree-Fock equations provide effective mean-field descriptions for the dynamics of large fermionic systems and play a fundamental role in many area…
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…
