论文摘要
Weyl半学宿主相对论手性准颗粒，在外部电磁场存在下显示量子异常。在这里，在存在量化磁场的情况下，我们研究了Weyl Semimetals的纵向和平面磁电流系数中手性异常的表现。我们提出了一个一般框架，用于计算占据多个Landau水平的制度中的所有运输系数。我们明确表明，所有纵向和平面传输系数都显示出Shubnikov-de Haas，如量子振荡，它们在1/b中是周期性的。我们的计算恢复了半经典状态下的二次-B依赖性，并预测所有运输系数的超量器极限中的线性-B依赖性。
Weyl semimetals host relativistic chiral quasiparticles, which display quantum anomalies in the presence of external electromagnetic fields. Here, we study the manifestations of chiral anomalies in the longitudinal and planar magneto-transport coefficients of Weyl semimetals, in the presence of a quantizing magnetic field. We present a general framework for calculating all the transport coefficients in the regime where multiple Landau levels are occupied. We explicitly show that all the longitudinal and planar transport coefficients show Shubnikov-de Haas like quantum oscillations which are periodic in 1/B. Our calculations recover the quadratic-B dependence in the semiclassical regime, and predict a linear-B dependence in the ultra-quantum limit for all the transport coefficients.
