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 pairing of fermions lies at the heart of superconductivity and superfluidity. The stability of
these pairs determines the robustness of the superfluid state, and the quest for …

Recent experiments with ultra-cold atoms have demonstrated the possibility of realizing
fermionic superfluids with imbalanced spin populations experimentally. We discuss how …

We present an overview of recent developments in species-imbalanced ('polarized')
Feshbach-resonant Fermi gases. We summarize the current status of thermodynamics of …

We used radio-frequency spectroscopy to study pairing in the normal and superfluid phases
of a strongly interacting Fermi gas with imbalanced spin populations. At high spin …

Spin-polarized attractive Fermi gases in one-dimensional (1D) optical lattices are expected
to be remarkably good candidates for the observation of the Fulde-Ferrell-Larkin …

The pairing and superfluid phenomena in a two-component ultracold atomic Fermi gas is an
analogue of Cooper pairing and superconductivity in an electron system, in particular, the …

We present phase diagrams for a polarized Fermi gas in an optical lattice as a function of
temperature, polarization, and lattice filling factor. We consider the Fulde-Ferrel-Larkin …

Ultracold two-component Fermi gases with a tunable population imbalance have provided
an excellent opportunity for studying the exotic Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) …

This article presents a comparison of two finite-temperature BCS–Bose-Einstein
condensation (BEC) crossover theories above the transition temperature: Nozieres–Schmitt …
