1.5型超导体中的半Meissner态和非成对涡旋间相互作用
Semi-Meissner state and non-pairwise intervortex interactions in type-1.5 superconductors
摘要:
我们证明了多组分和层状超导系统中涡旋之间存在非成对相互作用力。也就是说,与大多数常见的模型相反,在一组这样的旋涡中的相互作用不是库仑力或汤川力的普遍叠加。其次,我们研究了1.5型双组分超导体半迈斯纳态中涡旋团的性质。我们发现,在一定条件下,非成对力可以有助于形成非常复杂的涡旋态的1.5型制度。
英文摘要:
We demonstrate existence of non-pairwise interaction forces between vortices in multicomponent and layered superconducting systems. That is, in contrast to most common models, the interactions in a group of such vortices is not a universal superposition of Coulomb or Yukawa forces. Next we consider the properties of vortex clusters in Semi-Meissner state of type-1.5 two-component superconductors. We show that under certain condition non-pairwise forces can contribute to formation of very complex vortex states in type-1.5 regimes.
