标题： Spinor Condensates on a Cylindrical Surface in Synthetic Gauge Fields

摘要： 我们指出，通过修改最近一个生成狄拉克弦实验的设置，可以在圆柱表面上创建一个准二维自旋玻色凝聚态，该表面具有合成磁场，方向垂直于圆柱表面向外。 合成磁场的形式为朗道规范。 它由自旋纹理的贝里相位产生，该自旋纹理被外部四极磁场所冻结。 与平面情况不同，存在两种类型的涡旋（称为A和B），它们具有相同的涡旋度。 对于$5\le S\le 9$的基态，是由位于圆柱体赤道圆周上的交替AB涡旋组成的一行。 对于更高值的$S$，A和B涡旋分裂成两行，并沿圆柱轴$z$相互偏移。 BEC在圆柱表面上的许多性质发生变化，这意味着在弯曲表面上的基态将出现许多丰富的现象。 显示英文摘要

摘要： We point out that by modifying the setup of a recent experiment that generates a Dirac string, one can create a quasi 2D spinor Bose condensate on a cylindrical surface with a synthetic magnetic field pointing radially outward from the cylindrical surface. The synthetic magnetic field takes the form of the Landau gauge. It is generated by the Berry's phase of a spin texture, frozen by an external quadrupolar magnetic field. Unlike in the planar case, there are two types of vortices (called A and B) with the same vorticity. The ground state for $5\le S\le 9$ consists of a row of alternating AB vortices lying at the equatorial circle of the cylinder. For higher values of $S$, the A and B vortices split into two rows and are displaced from each other along the cylindrical axis $z$. The fact that many properties of a BEC are altered in a cylindrical surface implies many rich phenomena will emerge for ground states in curved surfaces.
