准铁电超导体在非局域Pippard极限下的电动力学
Electrodynamics of Nearly Ferroelectric Superconductors in the non-local Pippard limit
摘要：
报道了近铁电超导（NFE-SC）薄膜中的磁场和长期电流结构。结果表明，与传统的超导薄膜不同，外部辐射引起电流条的交替图案。最里面的电流洪流的强度取决于激光场强度以及与铁电元件的共振。后者由Pippard非局部极限中的长期反射和随机散射建模。我们的计算表明，相应的磁场模式影响涡旋形成在这样的材料。
英文摘要：
We report the structure of the magnetic field and secular current in a Nearly Ferroelectric Superconducting (NFE-SC) thin film. It was shown that unlike in conventional superconducting films, the external radiation causes alternating pattern of current strips. The strength of the innermost current torrents is governed by the laser field intensity as well as resonance with the ferroelectric component. The latter is modeled by secular reflection and random scattering in the Pippard non-local limit. Our calculations suggest that corresponding magnetic field pattern affects vortex formation in such material.
