Fluctuation theory of Rashba Fermi gases: Gaussian and beyond
JP Vyasanakere, VB Shenoy - Physical Review B, 2015 - APS
Fermi gases with generalized Rashba spin-orbit coupling induced by a synthetic gauge field
have the potential of realizing many interesting states, such as rashbon condensates and
topological phases. Here, we address the key open problem of the fluctuation theory of such
systems and demonstrate that beyond-Gaussian effects are essential to capture the finite
temperature physics of such systems. We obtain their phase diagram by constructing an
approximate non-Gaussian theory. We conclusively establish that spin-orbit coupling can …
