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 …

We review the concepts and the present state of theoretical studies of spin-imbalanced
superfluidity, in particular the elusive Fulde–Ferrell–Larkin–Ovchinnikov (FFLO) state, in the …

We present a theoretical interpretation of a recent experiment presented by Zwierlein
[Nature (London) 442, 54 (2006)] on the density profile of Fermi gases with unbalanced spin …

We investigate the low-lying compression modes of a unitary Fermi gas with imbalanced
spin populations. For low polarization, the strong coupling between the two spin …

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 study the Fermi gas at unitarity and at T= 0 by assuming that, at high polarizations, it is a
normal Fermi liquid composed of weakly interacting quasiparticles associated with the …

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

The real-space densities of a polarized strongly interacting two-component Fermi gas of Li 6
atoms reveal two low-temperature regimes, both with a fully paired core. At the lowest …

The two-component Fermi gas is the simplest fermion system exhibiting superfluidity, and as
such is relevant to topics ranging from superconductivity to quantum chromodynamics …
