Superradiance with local phase-breaking effects

Understand

We study the superradiant evolution of a set of $N$ two-level systems spontaneously radiating under the effect of phase-breaking mechanisms.

• We investigate the dynamics generated by non-radiative losses and pure dephasing, and their interplay with spontaneous emission.
• Our results show that in the parameter region relevant to many solid-state cavity quantum electrodynamics experiments, even with a dephasing rate much faster than the radiative lifetime of a single two-level system, a sub-optimal collective superfluorescent burst is still observable.
• We also apply our theory to the dilute excitation regime, often used to describe optical excitations in solid-state systems.
