Quantum parameters governing superradiance in lanthanide complexesbmission

We present a theoretical investigation into the emergence of Dicke superradiance in low-dimensional systems of N two-level atoms. Our focus is on a family of lanthanide-based coordination complexes [1] as the active centers with different resonant frequencies and assumed to be coupled to a single cavity mode. We model the system within the Tavis-Cummings (TC) framework. Numerical simulations allow us to explore the interplay between the standard TC parameters in addition to different decoherence and noise channels like interatomic coupling and detuning. An analysis of the cavity Wigner distribution functions reveals how variations in parameter space influence the transition from independent atom dynamics to coherent states. We study the dipole correlations between atoms to identify specific regimes that foster enhanced collective emission. We aim to gain insights contributing to a deeper understanding of cooperative quantum phenomena that inform the design of complexes with efficient superradiant behavior.
