论文摘要
研究了竞争阶超导体的标准金兹堡 - 兰道模型。观察到该模型具有两个不同的涡流物种，因此具有两个不同的整数有价值的拓扑电荷。开发了任何物种（抗）涡旋之间的远程力的简单点粒子模型，并与完整田间理论的数值模拟进行了比较，发现了良好的一致性。一些结果非常违反直觉。例如，存在一个参数状态，其中一个物种的涡旋驱除了另一个物种的涡流和抗生效。
The standard Ginzburg-Landau model of competing-order superconductors is studied. It is observed that this model possesses two distinct species of vortex, and consequently has two distinct integer valued topological charges. A simple point particle model of long range forces between (anti)vortices of any species is developed and compared with numerical simulations of the full field theory, excellent agreement being found. Some of the results are quite counterintuitive. For example, a parameter regime exists where vortices of one species repel both vortices and antivortices of the other.
