Trapped Two-Dimensional Condensates with Synthetic Spin-Orbit Coupling

摘要: We study trapped 2D atomic Bose-Einstein condensates with spin-independent interactions in the presence of an isotropic spin-orbit coupling, showing that a rich physics results from nontrivial interplay between confinement and interatomic interactions. For low two types half-vortex solutions different winding occur, whereas strong-enough repulsive result stripe-phase similar to predicted for homogeneous condensates. Intermediate interaction regimes are characterized large enough coupling by hexagonally-symmetric phase triangular lattice density minima observed rapidly rotating
