Title: Strongly-correlated fermionic matter in the dilute limit

Abstract

We study the solution of the following problem: What are the ground-state properties of the many-body system composed of spin-l/2 fermions interacting via a zerorange, infinite scattering length contact interaction? Sometimes referred to as the 'George Bertsch problem', it is of particular interest in astrophysics in connection with the equation of state for neutron matter and has been revisited recently with the advent of experimental studies in ultracold fermionic atom gases of the crossover from the regime of Bardeen-Schriffer-Cooper (BCS) weakly-bound Cooper pairs to the regime of Bose-Einstein condensation (BEC) of diatomic molecules.
