阻挫多带超导

Frustrated multiband superconductivity

R. G. Dias, A. M. Marques

摘要:

我们表明,一个干净的多带超导体可能会显示一个或几个相变与温度的增加,或挫折配置的超导序参量的相对相位。当超导相的形成涉及两个以上的能带时,以及当排斥带间相互作用的数量为奇数时,这些转变可能发生。这些转变是由超导间隙的温度依赖性的斜率变化来表示的。

英文摘要:

We show that a clean multiband superconductor may display one or several phase transitions with increasing temperature from or to frustrated configurations of the relative phases of the superconducting order parameters. These transitions may occur when more than two bands are involved in the formation of the superconducting phase and when the number of repulsive interband interactions is odd. These transitions are signalled by slope changes in the temperature dependence of the superconducting gaps.
