扩展$s$态超导体中无序引起的节点提升：对铁磷族化合物的应用
Lifting of nodes by disorder in extended-$s$ state superconductors: application to ferropnictides
摘要：
我们用一个简单的模型证明了普通的无序是如何使一个具有节点的扩展- $s$（$A_{1g}$）对称超导态产生间隙的。的热力学性质，特别是$T$的依赖性的超流密度，从纯幂律行为的一个激活的concommitant交叉展出。我们讨论了这种情况下的铁磷族化合物超导体的实验应用。
英文摘要：
We show, using a simple model, how ordinary disorder can gap an extended-$s$ ($A_{1g}$) symmetry superconducting state with nodes. The concommitant crossover of thermodynamic properties, particularly the $T$-dependence of the superfluid density, from pure power law behavior to an activated one is exhibited. We discuss applications of this scenario to experiments on the ferropnictide superconductors.
