Time-resolved physical spectrum in cavity quantum electrodynamics

The time-resolved physical spectrum of luminescence is theoretically studied for a standard cavity quantum electrodynamics system. In contrast to the power steady state, correlation functions up present time are crucial construction spectrum, while correlations with future quantities inaccessible because causality, i.e., cannot be measured until comes. We find that this causality plays key role understand in which Rabi doublet can never seen during first peak oscillation. Furthermore, influence on transient magnitude some situations. also study dynamics Fano anti-resonance, where difference from highlighted.
