TL;DR
This paper introduces a novel energy concentration mechanism in an optical cavity with many atoms, leading to photon emission through cavity mirrors without external driving, challenging traditional approximations.
Contribution
It reveals a new photon emission process in strongly confined atom-cavity systems beyond the rotating wave approximation.
Findings
Photon emission occurs without external excitation.
Energy concentrates in the cavity-atom system.
The mechanism operates outside the rotating wave approximation.
Abstract
We present a mechanism of energy concentration in a system composed by an optical cavity and a large number of strongly confined atoms, which cannot be described in the rotating wave approximation. The mechanism consists in the emission of photons through the cavity mirrors even in the absence of external driving.
