Magnetoconductance of the quantum spin Hall state
Magnetoconductance of the quantum spin Hall state
We study numerically the edge magnetoconductance of a quantum spin Hall insulator in the presence of quenched nonmagnetic disorder. For a finite magnetic field $B$ and disorder strength $W$ on the order of the bulk gap ${E}_{g}$, the conductance deviates from its quantized value in a manner which appears to …
