Lattice assisted coupling in a spin-orbit coupled Bose-Einstein condensates: a pathway to generating stripe-phase like features.

We investigate the dynamics of a spin-orbit coupled Bose-Einstein condensate in the presence of a matching lattice. The lattice wavevector is chosen such that it can couple the two minima of the spin-orbit dispersion. We observe coherent Rabi oscillations between the relevant momentum states by quenching system parameters. The ground state phase diagram as a function of tunneling strength and spin-orbit detuning is also verified experimentally and compared to theoretical predictions. The experimentally realized ground state exhibits stripe-phase like properties. I will describe the experimental scheme and current results of the project.
