  • Title: Enhanced Bulk-Edge Coulomb Coupling in Fractional Fabry-Perot Interferometers.
    Author: von Keyserlingk CW, Simon SH, Rosenow B.
    Journal: Phys Rev Lett; 2015 Sep 18; 115(12):126807. PubMed ID: 26431008.
    Abstract:
    Recent experiments use Fabry-Perot (FP) interferometry to claim that the ν=5/2 quantum Hall state exhibits non-Abelian topological order. We note that the experiments appear inconsistent with a model neglecting bulk-edge Coulomb coupling and Majorana tunneling, so we reexamine the theory of FP devices. Even a moderate Coulomb coupling may strongly affect some fractional plateaus, but very weakly affect others, allowing us to model the data over a wide range of plateaus. While experiments are consistent with the ν=5/2 state harboring Moore-Read topological order, they may have measured Coulomb effects rather than an "even-odd effect" due to non-Abelian braiding.
