Non-Abelian statistics in the interference noise of the Moore-Read quantum Hall state
Abstract
We propose noise oscillation measurements in a double point contact, accessible with current technology, to seek for a signature of the non-abelian nature of the =5/2 quantum Hall state. Calculating the voltage and temperature dependence of the current and noise oscillations, we predict the non-abelian nature to materialize through a multiplicity of the possible outcomes: two qualitatively different frequency dependences of the nonzero interference noise. Comparison between our predictions for the Moore-Read state with experiments on =5/2 will serve as a much needed test for the nature of the =5/2 quantum Hall state.
