Studies of dressed states with coupling between spin and orbital-angular-momentum in a Bose condensate
POSTER
Abstract
We Raman-couple bare spin states of a Bose condensate with a transfer of orbital-angular-momentum (OAM), where one of the Raman beams is a Laguerre Gaussian beam. The dressed spin state in such systems is a superposition state consisting of bare spin states with different OAM. We characterize the spin texture, relevant gauge potentials and lifetime of these dressed states; it is studied in both trap geometries of harmonic potentials and ring-shaped potentials.
