In this report we discuss the dynamical response of heavy quantum impurities immersed in a
Fermi gas at zero and at finite temperature. Studying both the frequency and the time …

Cold atomic gases have become a paradigmatic system for exploring fundamental physics,
which at the same time allows for applications in quantum technologies. The accelerating …

High-resolution addressing of individual ultracold atoms, trapped ions or solid state emitters
allows for exquisite control in quantum optics experiments. This becomes possible through …

We consider 1D lattices described by Hubbard or Bose-Hubbard models, in the presence of
periodic high-frequency perturbations, such as uniform ac force or modulation of hopping …

The Frehlich polaron model describes a ubiquitous class of problems concerned with
understanding the properties of a single mobile particle interacting with a bosonic reservoir …

We discuss the interaction of a quantum impurity with a one-dimensional degenerate Bose
gas forming a Bose polaron. In three spatial dimension, the quasiparticle is typically well …

A major challenge in modern physics is to accurately describe strongly interacting quantum
many-body systems. One-dimensional systems provide fundamental insights because they …

Immersing a mobile impurity in a quantum many-body environment can reveal fundamental
properties of the background medium, hence providing a powerful probe of quantum matter …

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 …

In this work we study the Kubo-Martin-Schwinger (KMS) relation in the Yang-Gaudin model
of an interacting mobile impurity. We use the integrability of the model to compute the …
