论文摘要
我们提出在存在空间不均匀性的情况下，在Weyl半法中提出了非隔离的运输效应和涡旋响应，即Weyl锥的空间变化。我们表明，当频谱是各向异性的并且由于空间晶格变化而倾斜时，由于倾斜结构的有效磁场，人们就会面临广义量子异常。特别是，我们证明了依赖位置的倾斜参数会诱导局部涡度，从而在没有旋转或磁场的情况下会产生手性涡旋效应。结果，它将电场耦合到电场，从而导致异常的大厅效应。
We propose a non-dissipative transport effect and vortical response in Weyl semimetals in the presence of spatial inhomogeneities, namely a spatially varying tilt of the Weyl cones. We show that when the spectrum is anisotropic and tilted due to spatial lattice variations, one is confronted with generalized quantum anomalies due to the effective fields stemming from the tilt structure. In particular, we demonstrate that the position-dependent tilt parameter induces local vorticity, thus generating a chiral vortical effect even in the absence of rotation or magnetic fields. As a consequence, it couples to the electric field and thus contributes to the anomalous Hall effect.
