简谐+四次势中自旋轨道耦合旋转玻色-爱因斯坦凝聚体的基态结构

Ground state of a rotating spin-orbit-coupled Bose-Einstein condensate in a harmonic plus quartic potential

研究了囚禁于简谐+四次势中具有自旋轨道耦合相互作用的旋转玻色-爱因斯坦凝聚体的基态结构;考虑了自旋轨道耦合相互作用和旋转对基态结构的影响;结果发现在自旋轨道耦合相互作用与旋转共同作用下,系统呈现出丰富且新奇的基态结构,如条形、双排和蛇皮花斑状等.

We consider the ground-state structure of a rotating Bose-Einstein condensate with spin-orbit coupling which is confined in a harmonic plus qurtic potential. Combined effects of spin-orbit coupling and rotation on the ground-state structure of such a system are investigated in detail. Results show that a large number of novel ground-state structures,such as stripe, two rows, snakeskin piebald, and so on, can be produced under the combination of anisotropic spin-orbitcoupling and rotation.
