Graphene-plasmon-mediated coherent dynamics in an N-quantum-emitter system
Abstract:
This work presents a detailed analysis of the coherent interaction between quantum emitters (QEs) mediated by multiple scattering of surface plasmons (SPs) excited on a graphene substrate. Under specific conditions, this scattering leads to stationary states characterized by coherent population oscillations, in which energy is periodically and reversibly exchanged between the QEs. Depending on the initial conditions, the number of QEs, and their geometric arrangement, multiple configurations of population trapping can occur. By using an analytical approach, we calculate asymptotic dynamical quantities-such as exchange frequencies and amplitudes-directly from the initial conditions. This method predicts the final stationary state, thereby explaining the key results obtained from our full numerical formalism.
