Enhancement of condensate depletion due to spin-orbit coupling    [PDF]

Xiaoling Cui, Qi Zhou

We show that spin-orbit coupling(SOC) significantly enhances the depletion of a Bose-Einstein condensate. With decreasing anisotropy of SOC, both quantum and thermal depletion increase. Moreover, when SOC and interaction are isotropic, thermal depletion becomes divergent at any finite temperature in three dimension. We also point out that different types of SOC give rise to qualitatively different dependence of condensate depletion on microscopic variables including scattering length, strength of SOC and temperature, a novel feature that can be directly observed once these types of SOC are realized in experiments.
