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 …

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 …

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 …

Recent experimental and theoretical progress has elucidated the tunable crossover, in
ultracold Fermi gases, from BCS-type superconductors to BEC-type superfluids. The BCS …

We report the observation of pairing in a gas of atomic fermions with unequal numbers of
two components. Beyond a critical polarization, the gas separates into a phase that is …

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 …

It is well known that the momentum distribution of the two-component Fermi gas with large
scattering length has a tail proportional to 1/k4 at large k. We show that the magnitude of this …

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

This book, based on a graduate course given by the authors, is a pedagogic and self-
contained introduction to the renormalization group with special emphasis on the functional …
