Spin-orbit-coupling-induced resonance in an ultracold Bose gas

We study a two-component Bose gas with artificial spin-orbit coupling (SOC) which couples the center-of-mass momentum of an 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 three scattering channels can be induced by tuning the appropriate SOC strength. Our method can also be applied to a Fermi gas where resonance can also be induced with two- or three-dimensional SOC.
