研究了可混溶两组分玻色-爱因斯坦凝聚体中的涡旋多边形及其稳定性，发现涡旋多边形对总环流Q ≤5是稳定的，对Q =6是亚稳定的，对Q ≥7是不稳定的.作为高能物理中的一个相关模型，我们还研究了带反铁磁势项的baby-Skyrme模型的涡旋多边形，并对两个结果进行了比较。
We study vortex polygons and their stabilities in miscible two-component Bose-Einstein condensates, and find that vortex polygons are stable for the total circulationQ≤5, metastable forQ=6, and unstable forQ≥7. As a related model in high-energy physics, we also study the vortex polygon of the baby-Skyrme model with an anti-ferromagnetic potential term, and compare both results.
