Strong coupling of two quantum emitters to a single light mode: The dissipative Tavis-Cummings ladder
Nicolás Quesada · Physical Review A · 2012
A criterion for strong coupling between two quantum emitters and a single resonant light mode in a cavity is presented. The criterion takes into account the escape of cavity photons and the spontaneous emission of the emitters, which are modeled as two-level systems. By using such a criterion, the dissipative Tavis-Cummings ladder of states is constructed, and it is shown that the inclusion of one more emitter with respect to the Jaynes-Cummings (single emitter) case increases the effective parameter region in which $n\text{th}$-order Rabi splitting is observed.
