Universal phase structure of dilute Bose gases with Rashba spin-orbit coupling
Universal phase structure of dilute Bose gases with Rashba spin-orbit coupling
A Bose gas subject to a light-induced Rashba spin-orbit coupling possesses a dispersion minimum on a circle in momentum space; we show that kinematic constraints due to this dispersion cause interactions to renormalize to universal, angle-dependent values that govern the phase structure in the dilute-gas limit. We find that, regardless …
