论文摘要
我们使用波数据包动力学的半经典理论制定了手性涡度效应（CVE）及其概括称为广义涡度效应。我们将自旋涡流耦合考虑在内，并通过从Noether局部减去磁化强度来计算传输电荷电流。我们发现，CVE中的运输充电电流总是在相对论手性费米子中消失。该结果表明，在凝结物质系统中无法观察到它在诸如伪lorentz对称性的狄拉克/Weyl半学之类的浓缩物质系统中观察到。我们还证明，可以在属于点组$ d_n，c_n（n = 2、3、4、6）$和$ c_1 $的非顾问系统中观察到各向异性CVE，例如$ n $ type terlurium。
We formulate the chiral vortical effect (CVE) and its generalization called generalized vortical effect using the semiclassical theory of wave packet dynamics. We take the spin-vorticity coupling into account and calculate the transport charge current by subtracting the magnetization one from the Noether local one. We find that the transport charge current in the CVE always vanishes in relativistic chiral fermions. This result implies that it cannot be observed in transport experiments in condensed matter systems such as Dirac/Weyl semimetals with the pseudo-Lorentz symmetry. We also demonstrate that the anisotropic CVE can be observed in nonrelativistic systems that belong to the point groups $D_n, C_n (n = 2, 3, 4, 6)$, and $C_1$, such as $n$-type tellurium.
