Excitations in a spin-orbit coupled stripe phase*

Recent advances in the preparation and manipulation of supersolid-like states with ultracold atoms have opened new lines of inquiry into the dynamics of this novel state of matter. By employing synthetic spin-orbit coupling (SOC) and a weak optical lattice which couples the SOC dispersion minima, we produce a ground state configuration which exhibits characteristics of a supersolid state. In this work, we explore the excitations of such a state by manipulating the phase and amplitude of the optical lattice. These investigations shed light on the degree to which this dressed system simulates a supersolid state as well as other interesting phenomena.
