超导，一种宏观量子态的出现，产生独特的电磁响应，导致磁场的完美屏蔽和零电阻。在本文中，我们提出具有空间反转对称性破缺的超导体具有巨大的非互易光学现象，如光电流产生和二次谐波产生。非互易光学响应在低频区域表现出发散行为，并且起源于宇称破缺超导体特有的双重指标，即非互易超流密度和Berry曲率导数。此外，机制和频率依赖性与超导体中保持的时间对称性密切相关。这种关系对于探索超导对称性的时空结构是有用的。这些指标表征了非互易光学响应的低频特性，从而量化了超导体在非互易光学中的性能。
Superconductivity, an emergence of a macroscopic quantum state, gives rise to unique electromagnetic responses leading to perfect shielding of magnetic field and zero electrical resistance. In this paper, we propose that superconductors with the space-inversion symmetry breaking host giant nonreciprocal optical phenomena, such as photocurrent generation and second harmonic generation. The nonreciprocal optical responses show divergent behaviors in the low-frequency regime and originate from twofold indicators unique to parity-breaking superconductors, namely, the nonreciprocal superfluid density and the Berry curvature derivative. Furthermore, the mechanism and frequency dependence are closely tied to the preserved temporal symmetry in the superconductor. The relation is useful for probing the space-time structure of the superconducting symmetry. The indicators characterize the low-frequency property of nonreciprocal optical responses and hence quantify the performance of superconductors in nonreciprocal optics.
