The BEC-BCS Crossover in Ultracold Fermi Gases - Combescot, R.
in FIFTY YEARS OF NUCLEAR BCS: PAIRING IN FINITE SYSTEMS edited by Broglia, RA and Zelevinsky, V (2013) 
LPS


Abstract : We provide an introduction to the matter of ultracold Fermi gases and the observation of the BEC-BCS crossover in these systems. We discuss in particular the simple modelisation of these gases, the Fano-Feshbach resonance, the simple BCS model of the crossover, the equation of state at T = 0, experiments on superfluid vortices and on critical velocity, results with the T-matrix approximation, and the Fermi polaron.
