On the ground state phases in spin-orbit coupled Bose-Einstein condensates with weak repulsive interactions

摘要

We study the ground-state phases of spin-orbit coupled Bose-Einstein condensates with an equal combination of Rashba and Dresselhaus and with Rabi mixing in a quasi-one-dimension setting. We analyze the role of the parameters, namely, spin-orbit and Rabi couplings, and inter- and intra-species interactions in a weak harmonic trap.
