Impurities and polarons in bosonic quantum gases: a review on recent progress
This review describes the field of Bose polarons, arising when mobile impurities are
immersed into a bosonic quantum gas. The latter can be realized by a Bose-Einstein …

Observation of a smooth polaron-molecule transition in a degenerate Fermi gas
Understanding the behavior of an impurity strongly interacting with a Fermi sea is a long-
standing challenge in many-body physics. When the interactions are short ranged, two …

Impurities in a one-dimensional Bose gas: the flow equation approach
A few years ago, flow equations were introduced as a technique for calculating the ground-
state energies of cold Bose gases with and without impurities. In this paper, we extend this …

Impurity in a heteronuclear two-component Bose mixture
We study the fate of an impurity in an ultracold heteronuclear Bose mixture, focusing on the
experimentally relevant case of a K 41-Rb 87 mixture, with the impurity in a K 41 hyperfine …

Molecular impurities as a realization of anyons on the two-sphere
Studies on the experimental realization of two-dimensional anyons in terms of quasiparticles
have been restricted, so far, to only anyons on the plane. It is known, however, that the …

Effective pair interaction between impurity particles induced by a dense Fermi gas
D Mitrouskas, P Pickl - arXiv preprint arXiv:2105.02841, 2021 - arxiv.org
We study the dynamics of a small number of impurity particles coupled to the ideal Fermi gas
in a $ d $-dimensional box. The impurities interact with the fermions via a two-body potential …
