论文摘要
我们仔细检查了由时空扭转驱动的新型手性转运现象，即手性扭转效应（CTE）。我们在最一般的扭转重力理论中以有限的温度，密度和曲率计算扭转诱导的手性电流。结论通过包括弯曲并证实了CTE与Nieh-Yan异常之间的关系，可以补充有关CTE的先前研究。我们还分析了手性扭转电流对外部电磁场的响应。所得的拓扑电流类似于轴突电动力学中的拓扑电流。
We scrutinize the novel chiral transport phenomenon driven by spacetime torsion, namely the chiral torsional effect (CTE). We calculate the torsion-induced chiral currents with finite temperature, density and curvature in the most general torsional gravity theory. The conclusion complements the previous study on the CTE by including curvature and substantiates the relation between the CTE and the Nieh-Yan anomaly. We also analyze the response of chiral torsional current to an external electromagnetic field. The resulting topological current is analogous to that in the axion electrodynamics.
