Abstract

We propose an experiment to identify the topological order of the ν=52\nu=\frac{5}{2} state through a measurement of the electric conductance of a mesoscopic device. Our setup is based on interfacing ν=2, 52\nu=2, \ \frac{5}{2} and 33 in the same device. Its conductance can unambiguously establish or rule out the particle-hole symmetric Pfaffian topological order, which is supported by recent thermal measurements. Additionally, it distinguishes between the Moore-Read and Anti-Pfaffian topological orders, which are favored by numerical calculations.
