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 …

In an atomic gas near a Feshbach resonance, the energy of two colliding atoms is close to
the energy of a bound state, ie, a molecular state, in a closed channel that is coupled to the …

Spin–orbit coupling (SOC) is central to many physical phenomena, including fine structures
of atomic spectra and topological phases in ultracold atoms. Whereas, in general, SOC is …

This paper summarizes the experimental frontier of ultracold fermionic gases. It is based on
three lectures which one of the authors gave at the Varenna Summer School describing the …

We calculate the equation of state of a two-component Fermi gas with attractive short-range
interspecies interactions using the fixed-node diffusion Monte Carlo method. The interaction …

Motivated by recent efforts to achieve cold fermions pairing, we study the nonadiabatic
regime of the Bardeen-Cooper-Schrieffer state formation. After the interaction is turned on, at …

We determine the effects of quantum fluctuations about the T= 0 mean-field solution of the
BCS-BEC crossover in a dilute Fermi gas using the functional integral method. These …

Higgs and Goldstone modes are possible collective modes of an order parameter on
spontaneously breaking a continuous symmetry. Whereas the low-energy Goldstone …

We propose a novel mechanism for a nonequilibrium phase transition in a U (1)-broken
phase of an electron-hole-photon system, from a Bose-Einstein condensate of polaritons to …

We report a dramatic magnetic-field dependence in the lifetime of trapped, ultracold diatomic
molecules created through an s-wave Feshbach resonance between fermionic atoms. The …
