Calculation of the Spin-Dependent Optical Lattice in Rubidium Bose–Einstein Condensation

We provide a theoretical study to calculate the spin-dependent optical lattice with rubidium Bose–Einstein condensation (BEC) in a steady magnetic field. The optical dipole potential variation at different Zeeman levels are obtained. We also show that atoms can be transported in three dimensions by changing the polarization of the trapping field. An explanation of this transportation process in an atomic coordinate is presented.
