This report addresses topics and questions of common interest in the fields of ultra-cold
gases and nuclear physics in the context of the BCS–BEC crossover. By this crossover, the …

Feshbach resonances are the essential tool to control the interaction between atoms in
ultracold quantum gases. They have found numerous experimental applications, opening up …

This paper reviews recent experimental and theoretical progress concerning many-body
phenomena in dilute, ultracold gases. It focuses on effects beyond standard weak-coupling …

We review recent developments in the physics of ultracold atomic and molecular gases in
optical lattices. Such systems are nearly perfect realisations of various kinds of Hubbard …

The physics of quantum degenerate atomic Fermi gases in uniform as well as in
harmonically trapped configurations is reviewed from a theoretical perspective. Emphasis is …

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

The Fermi-Hubbard model is a key concept in condensed matter physics and provides
crucial insights into electronic and magnetic properties of materials. Yet, the intricate nature …

Magnetically tunable Feshbach resonances were employed to associate cold diatomic
molecules in a series of experiments involving both atomic Bose and two-spin-component …

The crossover from weak-coupling Bardeen-Cooper-Schrieffer (BCS) pairing to a Bose-
Einstein condensate (BEC) of tightly bound pairs, as a function of the attractive interaction in …

We established superfluidity in a two-state mixture of ultracold fermionic atoms with
imbalanced state populations. This study relates to the long-standing debate about the …
