我们表明，在多带超导体，即使是一个非常小的带间邻近效应可以导致超导涡旋之间的相互作用势产生长程涡间吸引力的质的变化。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。
We show that in multiband superconductors, even an extremely 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 an unusual response to low magnetic fields leading to phase separation into domains of two-component Meissner states and vortex droplets.
