Abstract: We developed an ab initio approach for the low-energy scattering problem of ultracold atoms with spin-orbit (SO) coupling. We derive the modified Bethe-Peierles boundary condition for the systems with SO coupling, and obtain the analytical expression of the low-energy inter-atomic scattering amplitude, as well as the algebra equation for the two-atom bound-state energy. With our result we examine the validity of the effective contact interaction for the SO-coupled ultracold gases. Collaborating with the USTC experimental group, we also study the stability of excited dressed state with SO coupling.
