Gauge-independent emission spectra and quantum correlations in the ultrastrong coupling regime of open system cavity-QED

Gauge-independent emission spectra and quantum correlations in the ultrastrong coupling regime of open system cavity-QED

A quantum dipole interacting with an optical cavity is one of the key models in cavity quantum electrodynamics (cavity-QED). To treat this system theoretically, the typical approach is to truncate the dipole to two levels. However, it has been shown that in the ultrastrong-coupling regime, this trun...
