Description

In solid-state systems, strong correlations cause the emergence of quasiparticles that are immune to local environmental perturbations. An example of such a system is the Quantum Hall Effect, in which electrons confined in two dimensions and subjected to a high perpendicular magnetic field give rise to fractionally charged quasiparticles (anyons) that are topologically protected. The statistics of anyons can be studied by interferometry techniques. To study the statistical behavior of anyons we use bilayer graphene in Fabry-Perot interferometer geometry. In this paper I will describe the techniques used in the fabrication process and some interferometry results.
