论文摘要
在耦合的gross-pitaevskii方程中,已在数值上模拟了两种具有显着不同质量的冷原子的诱捕的玻色 - 带有质量显着不同的冷原子的混合物。在相位分离方案中,可以使用由无涡流芯和被量子涡流穿透的壳体组成的配置。壳体中涡流的动态特性由多个参数确定。已经寻求与与核心相关的多个涡流的长寿命强非组织系统相对应的物理可实现的参数域。已经提出了数百个特征时间存在的三个涡旋对的许多现实数值示例。
A trapped Bose--Einstein-condensed mixture of two types of cold atoms with significantly different masses has been simulated numerically within the coupled Gross--Pitaevskii equations. A configuration consisting of a vortex-free core and a shell penetrated by quantum vortices is possible in the phase separation regime. The dynamic properties of vortices in the shell are determined by several parameters. Physically implementable parametric domains corresponding to long-lived strongly nonstationary systems of several vortices attached to the core have been sought. A number of realistic numerical examples of three vortex pairs existing for many hundreds of characteristic times have been presented.
