Gauge-Independent Emission Spectra in the Ultrastrong Coupling Regime (QW6B.1)
Presenter: Will Salmon, Queen's University
Emission spectra in the ultrastrong coupling regime are traditionally computed in a gauge-dependent manner. We present gauge-invariant spectra which show significant disagreement with previous results obtained using the standard quantum Rabi model.
