The authors report on the first experimental realization of the classical Dicke model. This is performed by making use of two nonlinearly coupled, synthetic LC circuits, implemented by means of active electrical networks. The presented setup is used to experimentally monitor important features of the Dicke model, such as the ground-state and excited-phase transitions, the co-existence of periodic and chaotic trajectories, and the classical version of the fidelity out-of-time-order-correlator or FOTOC.
