摘要

We investigate the effects of topological order on the transition temperature, Tc, and response functions in spin-orbit-coupled fermionic superfluids with a transverse Zeeman field in three dimensions. Our calculations include fluctuation effects beyond mean-field theory and are compatible with f-sum rules. In the topological phase we find that Tc can be as large as 10% of the Fermi temperature, which should be experimentally accessible in cold-gas experiments. At higher temperatures, above Tc, the spin and density response functions provide signatures of topological phases via the recombination or amplification of frequency-dependent peaks.
