Modified Bethe-Peierls boundary condition for ultracold atoms with
Spin-Orbit coupling    [PDF]

Peng Zhang, Long Zhang, Youjin Deng

We show that the Bethe-Peierls (BP) boundary condition should be modified for ultracold atoms with spin-orbit (SO) coupling. Moreover, we derive a general form of the modified BP boundary condition, which is applicable to a system with arbitrary kind of SO coupling. Our result is helpful for the study of both few-body and many-body physics in SO-coupled ultracold gases.
