Double quantum dots at the edge of Abelian and non-Abelian factional quantum Hall sates

ORAL

Abstract

We theoretically study two quantum dots tunnel coupled to the edge of Abelian and non-Abelian fractional quantum Hall states. We find a number of interesting low-energy fixed points which are a function of inter-dot coupling and separation. We study the stability and structure of the fixed points under various perturbations.
