Magnetotransport on quantum spin Hall edge coupled to bulk midgap states

|
By Youjian Chen, Wenjin Zhao, Elliott Runburg, David Cobden
| Physical Review B
We consider magnetotransport on a helical edge of a quantum spin Hall insulator, in the presence of bulk midgap states side coupled to the edge. In the presence of a magnetic field, the midgap levels are spin split, and hybridization of these levels with the itinerant edge states leads to backscattering, and the ensuing increase in the resistance.
