Proposed experiments to probe the non-abelian ν=5/2 quantum Hall state
Ady Stern, Bertrand I. Halperin
Abstract
We propose several experiments to test the non-abelian nature of quasi-particles in the fractional quantum Hall state of ν=5/2. One set of experiments studies interference contribution to back-scattering of current, and is a simplified version of an experiment suggested recently. Another set looks at thermodynamic properties of a closed system. Both experiments are only weakly sensitive to disorder-induced distribution of localized quasi-particles.
