偶然简并非常规对态的杂质诱导双跃迁

Impurity induced double transitions for accidentally degenerate unconventional pairing states

Bastian Zinkl, Manfred Sigrist

摘要:

非磁性杂质可以提升非常规配对态的偶然简并,例如最近提出的Sr $_2$ RuO $_4$的$(d + i g)$波态。这种类型的效应将导致杂质掺杂时的超导双跃迁。在一个模型计算中,它显示了这种行为如何取决于材料参数,以及如何可以检测到。

英文摘要:

Non-magnetic impurities can lift the accidental degeneracy of unconventional pairing states, such as the $(d + i g)$-wave state recently proposed for Sr$_2$RuO$_4$. This type of effect would lead to a superconducting double transition upon impurity doping. In a model calculation it is shown how this behavior depends on material parameters and how it could be detected.
