论文摘要
在经受扭转的Weyl半金属中，有两种不同的手性：i）扭曲晶体的（坐标空间）形状是手性的，ii）动量空间包含手性准粒子。在这里，我们使用相位空间（坐标和动量空间结合）构建了一种反常转运的一般动力学理论，该理论是由Weyl Systems中扭转引起的浆果曲率。我们描述了扭转如何产生手性化学电位，因此在存在背景磁场的情况下导致手性磁效应（CME）。我们建议测量扭转诱导的CME电流，以此作为检测坐标空间和动量空间手势之间异常耦合的一种方式。
In Weyl semimetals subjected to torsion, there are two different kinds of chirality: i) the (coordinate-space) shape of the twisted crystal is chiral, and ii) the momentum space contains chiral quasi-particles. Here we construct a general kinetic theory of anomalous transport using the phase space (coordinate and momentum spaces combined) Berry curvature induced by torsion in Weyl systems. We describe how torsion generates the chiral chemical potential, and thus leads to the Chiral Magnetic Effect (CME) in the presence of a background magnetic field. We propose to measure the CME current induced by the torsion as a way to detect the anomalous coupling between the coordinate-space and momentum-space chiralities.
