Edge reconstruction in the ν= 2/3 fractional quantum Hall state Academic Article uri icon


  • Abstract The edge structure of the ν= 2/3 fractional quantum Hall state has been studied for several decades, but recent experiments, exhibiting upstream neutral mode (s), a plateau at a Hall conductance of 1 3 (e 2/h) through a quantum point contact, and a crossover of the effective charge, from e/3 at high temperature to 2 e/3 at low temperature, could not be explained by a single theory. Here we develop such a theory, based on edge reconstruction due to a confining potential with finite slope, that admits an additional ν= 1/3 …
