论文摘要
我们在Rashba自旋轨道（SO）耦合Spin-1均匀的准二维（Quasi-2d）铁磁液体bose-notomagnetic bose-inenstein冷凝物中展示了条纹和超晶状体孤子的自发空间顺序。对于弱的耦合，孤子是$（-1,0，+ 1）$或$（0，+ 1，+ 2）$ type具有内在涡度的类型，括号中的数字分别表示旋转组件中的角动量$ f_z =+ 1,0，-1 $。对于中间的耦合，发现了三种类型的孤子：（a）圆形空气对称孤子，（b）圆形的对称$（-1,0,0，+ 1）$ - 和（c）$（0，+ 1，+ 1，+ 2）$ - 在上述组合中维持上述组合量。对于大型耦合，除了圆形的孤子子外，还发现了准脱位条纹和超晶格孤子。超晶状体孤子在总密度中形成2D方格结构，如超固体中。在组件密度中，它可能具有（i）1D条纹图案或（ii）2D平方晶格结构。
We demonstrate spontaneous spatial order in stripe and super-lattice solitons in a Rashba spin-orbit (SO) coupled spin-1 uniform quasi-two-dimensional (quasi-2D) ferromagnetic Bose-Einstein condensate. For weak SO coupling, the solitons are of the $(- 1,0,+ 1)$ or $(0,+ 1,+ 2)$ type with intrinsic vorticity, where the numbers in the parentheses denote angular momentum in spin components $F_z=+1,0,-1$, respectively. For intermediate SO coupling, three types of solitons are found: (a) circularly-asymmetric solitons, (b) circularly-symmetric $(- 1,0,+ 1)$- and (c) $(0,+ 1,+ 2)$-type multi-ring solitons maintaining the above-mentioned vortices in respective components. For large SO coupling, quasi-degenerate stripe and super-lattice solitons are found in addition to the circularly-asymmetric solitons. A super-lattice soliton forms a 2D square lattice structure in the total density as in a super-solid; in component densities it may have either (i) a 1D stripe pattern or (ii) a 2D square lattice structure.
