Light-Induced Magnetic Fields for Neutral Atoms

Abstract

We explore light-induced magnetic fields for neutral atoms, which arise when atoms adiabatically follow spatially varying dressed states. We investigate normal modes resulting from phenomenological equations for atoms with different spin in a cigar-shaped harmonic trap, in such magnetic fields and with spin drag present. Within the adiabatic approximation, we determine the light-induced magnetic field and we propose a setup to implement this in our experiment. Our results pave the way for studying transverse spin transport in the intrinsic regime.
