Abstract

The t -matrix approximation applies to a low-density (or dilute) Fermi gas with a short-range interparticle interaction, either attractive or repulsive. This chapter considers the nonequilibrium (time-dependent) version of the t -matrix approximation for fermions in the normal phase, in the perspective of applying it to the BCS–BEC crossover.
