Superradiance Transition in Graphene

Quantum Physics 2020-02-11 v3 Other Condensed Matter

Abstract

We study theoretically and numerically the conditions required for the appearance of a superradiance transition in graphene. The electron properties of graphene are described in the single pzp_z-orbital tight-binding approximation, in which the model is reduced to the effective two-level pseudo-spin 1/21/2 system. For each level we introduce the electron transfer rate of escape into a continuum. We demonstrate that, under some conditions, the superradiance experiences the maximal quantum coherent escape to the continuum.
