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 …

Matter at high density and low temperature is expected to be a color superconductor, which
is a degenerate Fermi gas of quarks with a condensate of Cooper pairs near the Fermi …

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 report the realization of a novel degenerate Fermi mixture with an SU (2)× SU (6)
symmetry in a cold atomic gas. We successfully cool the mixture of the two fermionic …

We have observed phase separation between the superfluid and the normal component in a
strongly interacting Fermi gas with imbalanced spin populations. The in situ distribution of …

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 …

Inhomogeneous superconductors and inhomogeneous superfluids appear in a variety of
contexts including quark matter at extreme densities, fermionic systems of cold atoms, type-II …

A single down-spin fermion with an attractive zero-range interaction with a Fermi sea of up-
spin fermions forms a polaronic quasiparticle. The associated quasiparticle weight vanishes …

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 …
