摘要:

在激光诱导自旋-轨道耦合作用下,相互作用的超冷旋量玻色-爱因斯坦凝聚体可获得由非线性类狄拉克方程描述的准相对论性质.我们表明,作为一个结果的自旋-轨道耦合和非线性的冷凝物可能会成为自陷,类似于所谓的手性限制,以前研究的背景下,大量的Thirring模型。我们首先考虑1D几何形状的自约束凝聚提出了一个有趣的正弦依赖于粒子间的相互作用。我们进一步表明,多维手征限制也是可能的适当可行的激光安排下,并讨论了2D和3D凝聚体,这显着不同于1D的情况下的属性。

英文摘要:

In the presence of a laser-induced spin-orbit coupling an interacting ultra cold spinor Bose-Einstein condensate may acquire a quasi-relativistic character described by a non-linear Dirac-like equation. We show that as a result of the spin-orbit coupling and the non-linearity the condensate may become self-trapped, resembling the so-called chiral confinement, previously studied in the context of the massive Thirring model. We first consider 1D geometries where the self-confined condensates present an intriguing sinusoidal dependence on the inter-particle interactions. We further show that multi-dimensional chiral-confinement is also possible under appropriate feasible laser arrangements, and discuss the properties of 2D and 3D condensates, which differ significantly from the 1D case.
