Abstract

Synopsis: Atomic spin orbit coupling (SOC) can be synthesized with modulating gradient magnetic field (GMF). This is confirmed through studying collective dipole oscillations for a spin-1 atomic condensate in a harmonic trap after abruptly turning on SOC, and studying adiabatically adjusted equilibrium states when SOC strength is slowly ramped up. Further measurements reveal that SOC can be enhanced when the GMF modulation frequency approaches trapping frequency.
