Counterpropagating topological and quantum Hall edge channels

Counterpropagating topological and quantum Hall edge channels

The quantum spin Hall effect disappears at high magnetic fields when the band inversion is lifted. The authors demonstrate that in contrast, in disordered samples, counter-propagating topological and quantum Hall edge channels prevent the detection of the trivial gap, explaining a previous observati...
