多组分超导中的涌现现象:焦点问题简介

Emergent phenomena in multicomponent superconductivity: an introduction to the focus issue

Milorad V. Milošević, Andrea Perali

摘要:

多组分超导是许多不同超导材料中的一种新的量子现象,例如在不同费米表面打开不同超导能隙的多带超导,在原子尺度上设计以进入量子限制区的薄膜,多层,氧化物界面处的二维电子气,以及不同电子轨道或不同载流子参与超导凝聚体形成的复杂材料。在所有这些系统中,多组分超导波函数的自由度增加,使得出现了单组分超导体中无法获得的量子效应。在这篇社论中,我们介绍了目前的焦点问题,探索复杂但迷人的多组分超导物理。

英文摘要:

Multicomponent superconductivity is a novel quantum phenomenon in many different superconducting materials, such as multiband ones in which different superconducting gaps open in different Fermi surfaces, films engineered at the atomic scale to enter the quantum confined regime, multilayers, two-dimensional electron gases at the oxide interfaces, and complex materials in which different electronic orbitals or different carriers participate in the formation of the superconducting condensate. In all these systems the increased number of degrees of freedom of the multicomponent superconducting wave-function allows for emergent quantum effects that are otherwise unattainable in single-component superconductors. In this editorial paper we introduce the present focus issue, exploring the complex but fascinating physics of multicomponent superconductivity.
