论文摘要
我们证明了在Rashba旋转轨道（SO）耦合的Spin-1和Spin-2 Quasi-Two-Two-two二维非尺寸的非磁性bose-indetic bose-inerstein冷凝物（BEC）中，在Rashba旋转轨道（SO）中自发产生的空间周期性超固体超晶状体和条纹孤子（BEC）。弱所谓的旋转1 bec中的孤子是$（-1、0，+1）$和$（0，+1，+2）$类型的圆形对称，并且具有固有的涡度；括号中的数字分别是超自旋组件中的绕组数字$+1，0，-1 $。所谓的Spin-2 BEC中的圆形对称词素的类型为$（-2，-1、0，+1，+2）$和$（-1、1、0、0，+1，+2，+3）$，前者是基端状态，绕组数字对应于旋转组件$ + + + + + + +2、 +1、0、0，-1，-1，-1，-1，-2，-2，-2 $，-2 $。为了获得更强的So耦合强度，这些孤子在保留绕组数字的同时获得了多种结构。除了圆形的孤子，除了圆形的孤子外，准脱位条纹和超晶状体孤子，还以激发的固定状态出现，以在Spin-1和Spin-2 BEC中具有更强的SO偶联强度。 pla-cl.tex
We demonstrate spontaneous generation of spatially-periodic supersolid-like super-lattice and stripe solitons in Rashba spin-orbit (SO) coupled spin-1 and spin-2 quasi-two-dimensional nonmagnetic Bose-Einstein condensates (BECs). The solitons in a weakly SO-coupled spin-1 BEC are circularly-symmetric of $(-1, 0, +1)$ and $(0, +1, +2)$ types and have inherent vorticity; the numbers in the parentheses are the winding numbers in hyper-spin components $+1, 0, -1$, respectively. The circularly-symmetric solitons in an SO-coupled spin-2 BEC are of types $(-2, -1, 0, +1, +2)$ and $(-1, 0, +1, +2, +3)$ with the former being the ground state, where the winding numbers correspond to spin components $+2, +1, 0, -1, -2$, respectively. For stronger SO-coupling strengths, these solitons acquire a multiring structure while preserving the winding numbers. Quasi-degenerate stripe and super-lattice solitons, besides a circularly-asymmetric soliton, also emerge as excited stationary states for stronger SO-coupling strengths in spin-1 and spin-2 BECs. pla-cl.tex
