旋转下自旋-轨道耦合玻色-爱因斯坦凝聚体的Phase diagrams和Fermi估计

Phase diagrams and Thomas-Fermi estimates for spin-orbit coupled Bose-Einstein Condensates under rotation

Amandine Aftalion, Peter Mason

摘要:

我们提供了完整的相图描述的旋转和Rashba自旋轨道耦合的综合影响下的一个被困旋量BEC的基态。不同参数之间的相互作用(旋转的大小,自旋轨道耦合和相互作用的强度)导致了丰富的基态物理,我们分类。我们解释了一些功能分析在T-Fermi近似,写作的总密度,总相位和自旋方面的问题。特别地,我们分析了巨skyrmion,发现在强分凝情况下,它是1次的。在相图的某些区域,我们将模式与铁磁能量联系起来。

英文摘要:

We provide complete phase diagrams describing the ground state of a trapped spinor BEC under the combined effects of rotation and a Rashba spin-orbit coupling. The interplay between the different parameters (magnitude of rotation, strength of the spin-orbit coupling and interaction) leads to a rich ground state physics that we classify. We explain some features analytically in the Thomas-Fermi approximation, writing the problem in terms of the total density, total phase and spin. In particular, we analyze the giant skyrmion, and find that it is of degree 1 in the strong segregation case. In some regions of the phase diagrams, we relate the patterns to a ferromagnetic energy.
