论文摘要
基于玻尔兹曼方程，具有电子波数据包的半经典运动方程式，在相空间中由于浆果曲率而引起的横向电流。结果表明，由于“异常速度”和“有效的洛伦兹力”的贡献完全被取消，因此由于相浆曲率而引起的大厅效应是不存在的。
Transverse current due to Berry curvature in phase space is formulated based on the Boltzmann equations with the semiclassical equations of motion for an electron wave packet. It is shown that the Hall effect due to the phase space Berry curvature is absent because the contributions from "anomalous velocity" and "effective Lorentz force" are completely cancelled out.
