论文摘要
从理论上讲，我们在存在杂质散射的情况下研究了三维自旋1手性效率系统中的量子转运。在自洽的出生近似中，我们发现了状态密度的峰结构，并在零能量周围显着抑制了电导率。与Weyl fermion不同，零能量的电导率较少取决于杂质浓度。这些特性源自自旋1手性武器的平坦带结构。
We theoretically study the quantum transport in a three-dimensional spin-1 chiral fermion system in the presence of impurity scattering. Within the self-consistent Born approximation, we find peak structure of the density of states and significant suppression of electrical conductivity around the zero energy. The zero-energy conductivity depends less on impurity concentration, unlike a Weyl fermion. These properties originate from the flat band structure of spin-1 chiral fermion.
