Strong coupling optical spectra in dipole-dipole interacting optomechanical Tavis-Cummings models

TL;DR

This paper theoretically explores how dipole-dipole interactions affect the emission spectra in a hybrid optomechanical system with strong atom-cavity and optomechanical couplings, including effects of mechanical and photon losses.

Contribution

It introduces a detailed theoretical analysis of the emission spectrum in a dipole-dipole interacting optomechanical Tavis-Cummings model under strong coupling conditions.

Findings

Dipole-dipole interaction significantly alters the emission spectrum.

The model accounts for mechanical losses and spontaneous emission effects.

Strong coupling regimes reveal distinct spectral features.

Abstract

We theoretically investigate the emission spectrum of an optomechanical Tavis-Cummings model: two dipole-dipole interacting atoms coupled to an optomechanical cavity (OMC). In particular, we study the influence of dipole-dipole interaction (DDI) on the single-photon spectrum emitted by this hybrid system in the presence of a strong atom-cavity as well as strong optomechanical interaction (hereinafter called the strong-strong coupling). We also show that our analysis is amenable to inclusion of mechanical losses (under the weak mechanical damping limit) and single-photon loss through spontaneous emission from the two-level emitters under a non-local Lindblad model.
