We find that the T-unstable QH states can have a phase transition on the edge which causes a binding between electrons and reduces the number of gapless edge branches. After the binding transition, the single-electron tunneling into the edge gains a finite energy gap, and only certain multi-electron co-tunneling (such as three-electron co-tunneling for $
u=9/5$ edges) can be gapless. Similar phenomenon also appear for edge state on the boundary between certain QH states. For example edge on the boundary between $
u=2$ and $
u=1/5$ states only allow three-electron co-tunneling at low energies after the binding transition. | | Source: | arXiv, cond-mat/9903275 | | Services: | Forum | Review | PDF | Favorites | |
