Localized modes in dense repulsive and attractive Bose-Einstein condensates with spin-orbit and Rabi couplings
Localized modes in dense repulsive and attractive Bose-Einstein condensates with spin-orbit and Rabi couplings
We consider a binary Bose-Einstein condensate with linear and nonlinear interactions between its components, which emulate the spinor system with spin-orbit (SO) and Rabi couplings. For a relatively dense condensate, one-dimensional coupled equations with the nonpolynomial nonlinearity of both repulsive and attractive signs are derived from the three-dimensional Gross-Pitaevskii equations. …
