# Supersolid phase of a spin-orbit-coupled Bose-Einstein condensate: a perturbation approach

@inproceedings{Martone2021SupersolidPO, title={Supersolid phase of a spin-orbit-coupled Bose-Einstein condensate: a perturbation approach}, author={Giovanni I. Martone and Sandro Stringari}, year={2021} }

The phase diagram of a Bose-Einstein condensate with Raman-induced spin-orbit coupling includes a stripe phase with supersolid features. In this work we develop a perturbation approach to study the ground state and the Bogoliubov modes of this phase, holding for small values of the Raman coupling. We obtain analytical predictions for the most relevant observables (including the periodicity of stripes, sound velocities, compressibility, and magnetic susceptibility) which are in excellent… Expand
