Abstract
One aspect of solid-state photonic devices that distinguishes them from their atomic counterparts is the unavoidable interaction between system excitations and lattice vibrations of the host material. This coupling may lead to surprising departures in emission properties between solid-state and atomic systems. Here we predict a striking and important example of such an effect. We show that in solid-state cavity quantum electrodynamics, interactions with the host vibrational environment can generate quantum cavity-emitter correlations in regimes that are semiclassical for atomic systems. This behaviour, which can be probed experimentally through the cavity emission properties, heralds a failure of the semiclassical approach in the solid-state, and challenges the notion that coupling to a thermal bath supports a more classical description of the system. Furthermore, it does not rely on the spectral details of the host environment under consideration and is robust to changes in temperature. It should thus be of relevance to a wide variety of photonic devices.
Highlights
The diversity of systems studied in cavity quantum electrodynamics (CQED) places the subject at the heart of many prospective quantum and classical technologies
The dips lie at resonances of the first two eigenstates of the two level emitter (TLE)-cavity system, that is, the first rung of the dressed state ladder [see
We have shown that the presence of a thermal environment allows one to generate light-matter quantum correlations in solid-state CQED systems within otherwise semiclassical regimes
