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 theory of the strong interaction, quantum chromodynamics (QCD), describes the
generation of hadronic masses and the state of hadronic matter during the early stages of …

Superconductivity and superfluidity of fermionic and bosonic systems are remarkable many-
body quantum phenomena. In liquid helium and dilute gases, Bose and Fermi superfluidity …

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 …

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 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 …

Phase transitions are dramatic phenomena: water freezes into ice, atomic spins
spontaneously align in a magnet, and liquid helium becomes superfluid. Sometimes, such a …

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 …

We study resonantly-paired s-wave superfluidity in a degenerate gas of two species
(hyperfine states labeled by↑,↓) of fermionic atoms when the numbers N↑ and N↓ of the …
