标题： Unconventional and anomalous magnetic field distribution in a bilayer superconductor with geometric constraints

摘要： 我们研究了多组件超导体中的磁场分布。 我们考察了一种层状超导体和一种双组分单层超导体。 我们在间隙函数相空间中具有拐点结构的半量子涡旋存在的情况下，评估了磁场的分布。 我们还研究了在双组分超导体中构造的结点孤子的磁场分布。 我们研究了几何约束对多组件超导体的影响，其中几何约束意味着系统在一个方向上被紧致化，使得该方向上的电流变得微不足道。 这对应于在这个方向上的规范固定。 出现了一种非常规的磁场分布；这里非常规的意思是磁场未完全屏蔽，这被称为反常迈斯纳效应。 我们认为这种反常行为会产生一个无质量的规范场。 显示英文摘要

摘要： We investigate the magnetic field distribution in multi-component superconductors. We examine a layered superconductor and a two-component one-layer superconductor. We evaluate the field distribution in the presence of a half-flux quantum vortex with a kink structure in the phase space of gap functions. We also examine the magnetic field distribution of a knot soliton which is formulated in a two-component superconductor. We investigate the effect of geometric constraints for multi-component superconductors, where the geometric constraint means that the system is compactified in one direction so that the current in this direction becomes vanishingly small. This corresponds to the gauge fixing in this direction. An unconventional magnetic field distribution takes place; here the unconventional means that the magnetic field is screened incompletely which would be called the anomalous Meissner effect. We argue that this anomalous behavior creates a massless gauge field.
