Theoretical description of a micromaser in the ultrastrong-coupling regime
Theoretical description of a micromaser in the ultrastrong-coupling regime
We theoretically investigate an ultrastrongly-coupled micromaser based on Rydberg atoms interacting with a superconducting LC resonator, where the common rotating-wave approximation and slowly-varying-envelope approximation are no longer applicable. The effect of counter-rotating terms on the masing dynamics is studied in detail. We find that the intraresonator electric energy declines and …
