Universality in the BCS - BEC Crossover in Cold Fermion Gases

Sebastian Diehl

We address the finite temperature phase diagram of ultracold fermionic atoms across a Feshbach resonance based on a functional integral for an atom-molecule model. This allows to fully exploit the presence of the global symmetry of phase rotations, U(1). Both the equation of state and the classification of the thermodynamic phases are obtained from a symmetry consideration. We focus on the universal aspects associated to narrow and broad resonances, in turn connected by an additional form of crossover. The narrow resonance limit can be solved exactly above the critical temperature. We also assess deviations from the broad resonance universality which have recently been probed experimentally.We address the finite temperature phase diagram of ultracold fermionic atoms across a Feshbach resonance based on a functional integral for an atom-molecule model.
