The pseudogap regime in the unitary Fermi gas
Department or Administrative Unit
We discuss the pseudogap regime in the unitary Fermi gas (UFG), with a particular emphasis on the auxiliary-field quantum Monte Carlo (AFMC) approach. We discuss possible signatures of the pseudogap, review experimental results, and survey analytic and quantum Monte Carlo techniques before focusing on AFMC calculations in the canonical ensemble. For the latter method, we discuss results for the heat capacity, condensate fraction, energy-staggering pairing gap, and spin susceptibility, and compare to experiment and results of other theoretical methods.
