Shot noise as a diagnostic in the fractional quantum Hall edge zoo
Sourav Manna, Ankur Das, Yuval Gefen +1
The filling is the simplest paradigmatic example of a fractional quantum Hall state, which contains counter-propagating edge modes. These modes can be either in the unequi…
Multiple Mechanisms for Emerging Conductance Plateaus in Fractional Quantum Hall States

The nature of the bulk topological order of the 5/2 non-Abelian fractional quantum Hall state and the steady-state of its edge are long-studied questions. The most promising non-Ab…
Generalized topological bulk-edge correspondence in bulk-Hermitian continuous systems with non-Hermitian boundary conditions
Orr Rapoport, Moshe Goldstein
The bulk-edge correspondence (BEC) is the hallmark of topological systems. In continuous (nonlattice) Hermitian systems with an unbounded wave vector, it was recently shown that th…
