论文摘要
我们研究了由由静电和矢量电势组成的屏障在多翼半金属中产生的准粒子的隧穿,沿透射轴均匀地存在于有限区域中。多翼半学的分散在一个方向上是线性的(例如$ k_z $),并且与$ k_ \ perp^j $成比例的垂直于其(其中$ k_ \ perp = \ sqrt {k_x^k_x^2+k_y^2} $)。因此,我们研究了屏障垂直于$ k_z $和$ k_x $的情况。为了进行比较,我们还陈述了Weyl Semimetal的相应结果。
We investigate the tunneling of the quasiparticles arising in multi-Weyl semimetals through a barrier consisting of both electrostatic and vector potentials, existing uniformly in a finite region along the transmission axis. The dispersion of a multi-Weyl semimetal is linear in one direction (say, $k_z$), and proportional to $k_\perp^J$ in the plane perpendicular to it (where $k_\perp =\sqrt{k_x^2+k_y^2}$). Hence, we study the cases when the barrier is perpendicular to $k_z$ and $k_x$, respectively. For comparison, we also state the corresponding results for the Weyl semimetal.
