论文摘要
我们表明，通过孤立的磁空产生的杂散场可用于捕获超低原子。特别是，可以通过将两个孤立的天空组合起来来创建超低原子的环形和双孔捕获电位。这些磁陷阱的几何大小，潜在的障碍，陷阱频率和主要损耗率可以通过外部磁场或设备配置来调节。这里的结果对于通过使用现代旋转技术来操纵磁性天空来开发原子能设备可能很有用。
We show that the stray field generated by isolated magnetic skyrmions can be used to trap ultracold atoms. Specially, ring-shaped and double-well trapping potentials for ultracold atoms can be created by combining the field from two isolated skyrmions. The geometry size, potential barrier, trapping frequency and Majorana loss rate of these magnetic traps can be tuned by the external magnetic field or device configuration. The results here could be useful to develop atomtronics devices by manipulating the magnetic skyrmions with modern spintronics techniques.
