倾斜Weyl半金属中的Onsager-Casimir倒易关系
On the Onsager-Casimir reciprocal relations in a tilted Weyl semimetal
摘要：
Onsager-Casimir倒易关系是非平衡统计系统的基本对称性。本文研究了倾斜Weyl半金属Co $_3$ Sn $_2$ S $_2$的时间反演对称性破缺时的一种不寻常的手征霍尔效应。确认满足互惠关系。由于两个Berry曲率效应，反常速度和手征化学势，有助于观察到的霍尔效应，相互关系表明他们有趣的联系。
英文摘要：
The Onsager-Casimir reciprocal relations are a fundamental symmetry of nonequilibrium statistical systems. Here we study an unusual chirality-dependent Hall effect in a tilted Weyl semimetal Co$_3$Sn$_2$S$_2$ with broken time reversal symmetry. It is confirmed that the reciprocal relations are satisfied. Since two Berry curvature effects, an anomalous velocity and a chiral chemical potential, contribute to the observed Hall effect, the reciprocal relations suggest their intriguing connection.
