Directly probing the chirality of Majorana edge states

Abstract

We propose to directly probe the chirality of Majorana edge states in 2D topological superconductors using polarization selective photon absorption. When shining circularly polarized light on a 2D topological superconductor in disk geometry, the photons can excite quasiparticles only when the polarization of the light matches the chirality of the Majorana edge states required by the angular momentum conservation. Hence one can obtain the chirality of the Majorana edge states by measuring the photon absorption rate. We show that the polarization selective photon absorption can also serve as a smoking gun evidence of the chiral Majorana edge mode. Our results pave a new way of detecting, investigating and manipulating the chiral Majorana edge states.
