This article reviews theoretical and experimental developments for one-dimensional Fermi
gases. Specifically, the experimentally realized two-component delta-function interacting …

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 …

We review the recent theoretical and experimental progress regarding the generalized
hydrodynamics (GHD) behavior of the one-dimensional (1D) Bose gas with contact …

We study the properties of the Bose polaron, an impurity strongly interacting with a Bose-
Einstein condensate, using a field-theoretic approach and make predictions for the spectral …

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 …

In one dimension, the study of magnetism dates back to the dawn of quantum mechanics
when Bethe solved the famous Heisenberg model that describes quantum behaviour in …

This is a review of recent developments in Monte Carlo methods in the field of ultracold
gases. For bosonic atoms in an optical lattice we discuss path-integral Monte Carlo …

It is widely believed that the stationary properties after a quantum quench in integrable
systems can be described by a generalized Gibbs ensemble (GGE), even if all of the …

We derive exact analytic expressions for the n-body local correlations in the one-
dimensional Bose gas with contact repulsive interactions (Lieb-Liniger model) in the …

A degenerate Fermi gas is rapidly quenched into the regime of strong effective repulsion
near a Feshbach resonance. The spin fluctuations are monitored using speckle imaging …
