Cotunneling in the 5/2 fractional quantum Hall regime — •Robert Zielke, Bernd Braunecker, and Daniel Loss — University of Basel

We consider two fractional quantum Hall samples weakly coupled via a quantum dot and investigate whether there are specific signatures for the ν=5/2 wave functions, especially the Moore-Read wave function, in the tunneling between the edge states through the quantum dot. The focus is specifically on the cotunneling regime, both elastic and inelastic.
