论文摘要
在拓扑半学和绝缘子中，据报道，浆果曲率引起的负纵向磁力和角度依赖的平面霍尔效应。使用Boltzmann转运理论，我们为非平衡分布函数提供了封闭形式的表达，其中包括浆果曲率和洛伦兹力的效果。使用此公式，我们获得了Weyl半含量的电导率和电阻率张量的分析表达式，证明了两种效应之间的竞争引起的非单调场依赖性。
In topological semimetals and insulators, negative longitudinal magnetoresistance and angle-dependent planar Hall effect have been reported arising from the Berry curvature. Using the Boltzmann transport theory, we present a closed-form expression for the nonequilibrium distribution function which includes both the effects of the Berry curvature and Lorentz force. Using this formulation, we obtain analytical expressions for conductivity and resistivity tensors in Weyl semimetals demonstrating a non-monotonic field dependence arising from the competition between the two effects.
