Exact Conductance through Point Contacts in the ν=1/3 Fractional Quantum Hall Effect
P. Fendley, A. W. W. Ludwig, H. Saleur
Abstract
The conductance for tunneling through a point contact between two ν=1/3 quantum Hall edges is described by a universal scaling function, which has recently been measured experimentally. We compute this universal function exactly, by using the thermodynamic Bethe ansatz and a Boltzmann equation.
