The integral QHE : Topological considerations , edge states

  • Fig


Generally speaking, the occurrence of integer or rational-fraction quantum numbers in QM is a result either of some symmetry of the problem, or of topological considerations, or of both. However, as emphasized by Thouless, 1 those numbers that are the consequence of topology are usually much more stable against small perturbations than the symmetry-derived… (More)
