Quantum Transport in Spin-1 Chiral Fermion: Self-Consistent Born Approximation
arXiv:2207.06777 · doi:10.7566/JPSCP.38.011158
Abstract
Quantum transport for a spin-1 chiral fermion is studied within the self-consistent Born approximation. We find characteristic properties around zero energy, i.e., the peak structure of the density of states and significant suppression of electrical conductivity. These structures originate from the flat band and its interband effect.
