Quantum atomic and molecular gases are flexible systems for studies of fundamental many-
body physics. They have traditionally been produced in harmonic electromagnetic traps and …

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 …

Ultracold quantum gases offer a unique setting for quantum simulation of interacting many-
body systems. The high degree of controllability, the novel detection possibilities and the …

Quantum impurity models describe an atom or molecule embedded in a host material with
which it can exchange electrons. They are basic to nanoscience as representations of …

Fermi gases, collections of fermions such as neutrons and electrons, are found throughout
nature, from solids to neutron stars. Interacting Fermi gases can form a superfluid or, for …

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

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 …

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 …

One of the greatest challenges in modern physics is to understand the behaviour of an
ensemble of strongly interacting particles. A class of quantum many-body systems (such as …

The theory of the strong interaction, quantum chromodynamics (QCD), describes the
generation of hadronic masses and the state of hadronic matter during the early stages of …
