Spin-Orbit Coupling Induced Resonance in an Ultracold Bose Gas

Abstract

We study a two-component Bose gas with artificial spin-orbit coupling (SOC) which couples the center-of-mass momentum of atom to its internal states. We show that in this system resonance can be induced by tuning SOC strength. With a two-dimensional SOC, resonances in two scattering channels can be induced by tuning the aspect ratio of SOC strengths. With a three-dimensional SOC, resonance in all scattering channels can be induced by tuning the appropriate SOC strength. Similarly, we also find that in a Fermi gas with two- or three-dimensional SOC resonance can be induced by tuning SOC strength.
