Open cavity systems are of high interest in quantum optics and plasmonics and offer a variety of applications, including lasing/spasing and non-classical light generation. In many cavity-QED platforms, photons are usually described by lossless normal modes, e.g., in the Jaynes-Cummings model. However, for metallic or open cavities, the so-called quasinormal modes [1] (QNMs) with complex eigenfrequencies are more appropriate, and are the natural modes to quantize.
Using a recent developed quantization scheme [2] for three-dimensional open resonators on the basis of these QNMs, we explore the multi-photon regime in a plasmonic-photonic crystal cavity coupled to a two-level atom. On the basis of a generalized input-output theory for QNMs [3], we derive quantum correlations of the output fields using the QNM Lindblad master equation and compare the results to the phenomenological dissipative Jaynes-Cummings models.
