论文摘要
我们通过由由静电和矢量电位组成的屏障进行了伪季-1和伪源性-3/2准粒子的隧穿，沿透射轴均匀地存在于有限区域中。首先，我们在没有矢量电位的情况下发现隧道系数，电导率和FANO因素。然后，我们通过打开相关磁场来重复计算。这些功能显示出明显的区别，可用于识别半法的类型，尽管它们均表现出线性带跨点。
We investigate the tunneling of pseudospin-1 and pseudospin-3/2 quasiparticles through a barrier consisting of both electrostatic and vector potentials, existing uniformly in a finite region along the transmission axis. First, we find the tunneling coefficients, conductivities, and Fano factors in the absence of the vector potential. Then we repeat the calculations by switching on the relevant magnetic fields. The features show clear distinctions, which can be used to identify the type of semimetals, although both of them exhibit linear band-crossing points.
