Pseudogap effects of Fermi gases in the presence of a strong effective magnetic field.

We address the important question of how to characterize the normal state and the nature of noncondensed pairs in fermionic superflirids under the influence of a strong effective magnetic field. In ultracold gases, the magnetic field is implemented through rapid rotation or novel artificial field techniques. We consider the near-unitary regime, where noncondensed pairs are likely to be present at temperatures above the condensation temperature Tc. We show (based on Gor'kov theory) that these pairs are associated with a precursor of a vortex configuration. Importantly, this nonuniform normal state appears to enable "Bose condensation" in a field which is otherwise problematic due to the effective one-dimensionality of Landau-level dispersion.
