Tunable miscibility and thermalization in a spin-orbit coupled BEC

ORAL

Abstract

The commonly used relation for the miscible-immiscible transition for two-component Bose-Einstein condensates is reconsidered. Our study goes beyond the Thomas-Fermi approximation by considering the kinetic energy term in mean field theory [1]. Numerical solution of the time-dependent and time-independent Gross-Pitaevskii equations in the spin-orbit coupled BEC suggests a new phase boundary for the miscible-immiscible transition when kinetic energy becomes important. The possible implications of this kinetic energy effect on the thermalization of a binary BEC based on this miscibility transition are also discussed. \\[4pt] [1] L. Wen et al., Phys. Rev.
