Graphene Plasmon Excitation with Ground-State Two-Level Quantum Emitters

The transmission of a two-level quantum emitter in its ground state through a graphene nanosheet is investigated. The graphene plasmons (GPs) field distribution, especially the opposite orientations of the vertical electric field components on the two sides of the graphene nanosheet, produces a significant nonadiabatic process during the interaction between the emitter and the localized GPs. By taking into account the counterrotating terms, the excitation of the quantum emitter with simultaneous emission of a GP has a large probability. This happens for emitter speeds of about 10(-4) times the speed of light. For accelerated emitters, the GPs exhibit thermal field photon distribution with a high temperature. As a consequence, this study provides a promising platform to observe the dynamical Casimir effect as well as a simulation of the Unruh effect.

Automated summary

This study investigates the transmission of a two-level quantum emitter in its ground state through a graphene nanosheet and the nonadiabatic process produced by the graphene plasmons field distribution. It reveals a significant probability of exciting the quantum emitter and simultaneously emitting a GP, especially at speeds around 10^-4 times the speed of light. Furthermore, accelerated emitters cause GPs to exhibit a thermal field photon distribution with high temperature, providing a platform for observing the dynamical Casimir effect and simulating the Unruh effect.
