手征超导体的集体模和电磁响应

Collective modes and electromagnetic response of a chiral superconductor

Rahul Roy, Catherine Kallin

摘要:

受最近关于锶铼酸盐\cite{xia:167002}克尔效应测量的争论的启发,我们研究了一个干净的手征p波超导体的电磁响应。当考虑集体模的贡献时,干净的手征超导体中的霍尔响应比以前的理论预测小几个数量级,并且太小而无法解释实验。我们还发现了手征超导体集体模的一些不寻常的特征,即它们不是纯纵向的,而是与外横场耦合的。

英文摘要:

Motivated by the recent controversy surrounding the Kerr effect measurements in strontium ruthenate \cite{xia:167002}, we examine the electromagnetic response of a clean chiral p-wave superconductor. When the contributions of the collective modes are accounted for, the Hall response in a clean chiral superconductor is smaller by several orders of magnitude than previous theoretical predictions and is too small to explain the experiment. We also uncover some unusual features of the collective modes of a chiral superconductor, namely, that they are not purely longitudinal and couple to external transverse fields.
