文摘
- •
We determine the conditions for appearance of a superradiance transition (ST) in graphene.
- •
ST in a single-layer graphene is related to occurrence of an exceptional points (EP) and to overlapping of two resonances.
- •
In the undoped graphene case the superradiance transition occurs at the EP.
- •
The maximal efficiency of the electron transfer is related to the superradiance state.
