Superradiance in chaotic resonators

In collaboration with KAUST we demonstrated that a chaotic quantum resonator can be used to study the onset of superradiance, as predicted by Dicke. According to this theory, two-level atoms immersed in a common radiation field can synchronise and  emit energy at a rate faster than that predicted by incoherent spontaneous emission. Experimental demonstration of this theory have so far proven elusive due to the requirement on the coupling strength of the states. Our system, based on photonic crystal resonators with controlled loss channels, mimics the dynamics of an open many-body system and permits to explore experimentally a regime with favourable coupling strength between the superradiant states. The results have been published in Phys. Rev. X.


We experimentally investigated the onset of supperadiance in chaotic optical resonators realized with two-dimensional photonics crystals.
