Theory of the strong coupling between quantum emitters and propagating surface plasmons

Abstract

Here we present the theoretical foundation of the strong coupling phenomenon between quantum emitters and propagating surface plasmons observed in two-dimensional metal surfaces. For that purpose, we develop an ab-initio quantum framework that accounts for the coherent coupling be- tween emitters and surface plasmons and incorporates the presence of dissipation and dephasing. For both a single emitter and a disordered ensemble of emitters, our formalism is able to reveal the key physical mechanisms that explain the reported phenomenology and also to determine the physical parameters that optimize the strong coupling.
