Electrical conductivity and screening effect of spin-1 chiral fermions scattered by charged impurities
arXiv:2305.11631 · doi:10.1103/PhysRevB.108.085204
Abstract
We theoretically study the quantum transport in a three-dimensional spin-1 chiral fermion system in the presence of coulomb impurities based on the self-consistent Born approximation. We find that the flat-band states anomalously enhance the screening effect, and the electrical conductivity is increased in the low-energy region. It is also found that reducing the screening length leads to an increase in the forward scattering contribution and, thus, an increase in the vertex correction in the high-energy region.
