Theoretical description of a micromaser in the ultrastrong-coupling regime
We theoretically investigate an ultrastrong-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LC resonator, where the common rotating-wave approximation and slowly varying envelope approximation are no longer applicable.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 masing dynam...
