论文摘要
我们提出了一种方法，可以通过强电场的作用，通过其I-V特征的非线性部分在外部磁场或电气开路中奇异的磁场电场电压中奇怪的非线性部分，在强电场的作用下观察非中心对称Weyl半度值的手性磁效应。这种效果依赖于山谷选择性的加热，这通常会导致山谷人口不平衡。在存在外部磁场的情况下，这种山谷水平的Weyl半学通常会沿磁场的方向发展电流 - 手性磁效应。我们还讨论了一个特定的实验设置，以观察热电子的手性磁效应。
We propose a way to observe the chiral magnetic effect in non-centrosymmetric Weyl semimetals under the action of strong electric field, via the non-linear part of their I-V characteristic that is odd in the external magnetic field, or odd-in-magnetic field voltages in electrically open circuits. This effect relies on valley-selective heating in such materials, which in general leads to nonequilibrium valley population imbalances. In the presence of an external magnetic field, such a valley-imbalanced Weyl semimetal will in general develop an electric current along the direction of the magnetic field -- the chiral magnetic effect. We also discuss a specific experimental setup to observe the chiral magnetic effect of hot electrons.
