两带超导体中本征邻近效应引起的1.5型超导态

Type-1.5 Superconducting State from an Intrinsic Proximity Effect in Two-Band Superconductors

Egor Babaev, Johan Carlstrom, Martin Speight

摘要:

我们发现,在多带超导体中,即使是很小的带间邻近效应也可以通过产生长程涡间吸引力而导致超导涡旋之间的相互作用势发生质的变化。这种类型的涡旋相互作用导致对低磁场的不寻常响应,导致相分离成双组分迈斯纳态和涡旋液滴的域。

英文摘要:

We show that in multiband superconductors even small interband proximity effect can lead to a qualitative change in the interaction potential between superconducting vortices by producing long-range intervortex attraction. This type of vortex interaction results in unusual response to low magnetic fields leading to phase separation into domains of a two-component Meissner states and vortex droplets.
