We present a rigorous photonic mode model to describe the strong coupling between a monolayer of MoSe2 and a single gold nanoparticle. The onset of strong coupling is quantified by computing the three-dimensional hybrid quasinormal modes of the combined structure, allowing one to accurately model light-matter interactions without invoking the usual phenomenological theories of strong coupling. We explore the hybrid quasinormal modes as a function of gap size and temperature and find spectral…

Quantization of Quasinormal Modes for Open Cavities and Plasmonic Cavity Quantum Electrodynamics.
TLDR
A second quantization scheme based on quasinormal modes, which are the dissipative modes of leaky optical cavities and plasmonic resonators with complex eigenfrequencies, is introduced and gives a solid understanding to the limits of phenomenological dissipative Jaynes-Cummings models.
