Indications of a Luttinger liquid in the fractional quantum hall regime
Abstract
We have studied the transmission through a point contact in a gated GaAs-AlGaAs heterostructure. At the ν = 1/3 quantum Hall plateau measurements of the tunneling conductance exhibit non-Fermi liquid like resonance properties. The temperature dependence of the off-resonance conductances and resonance line shapes agrees with recent predictions of Luttinger liquid theory.
