RESONANT-TUNNELING BETWEEN QUANTUM HALL EDGE STATES

Resonant tunneling between fractional quantum Hall edge states is stud ied in the Luttinger liquid picture. For the nu = 1/3 Laughlin parent state, the resonance line shape is a universal function whose width sc ales to zero at zero temperature. Extensive quantum Monte Carlo simula tions are presented for nu = 1/3 which confirm this picture and provid e a parameter-free prediction for the line shape.
