Quantum coherence and speed limit in the mean-field Dicke model of superradiance
D. Z. Rossatto, D. P. Pires, F. M. de Paula +1
Dicke superrandiance is a cooperative phenomenon which arises from the collective coupling of an ensemble of atoms to the electromagnetic radiation. Here we discuss the quantifying…
