Inducing cooperative dynamics in an inhomogeneous many-emitter ensemble with a pulse sequence
Abstract
Driving a many-particle quantum system with an appropriately tuned external field can give rise to features in its nonequilibrium dynamics that are absent in the equilibrium counterpart. Cooperative dynamics in a dense ensemble of quantum emitters manifested through superradiance, a burst in the emission intensity as a function of time, is typically suppressed by spectral disparities among emitters in the ensemble. We demonstrate the enhancement of cooperative dynamics in a spectrally inhomogeneous ensemble of quantum emitters when it is driven by a periodic pulse sequence. Using both a semi-analytical mean-field solution and a digital quantum simulation, we examine the coherence of the pulse-driven ensemble and the intensity of the emitted radiation as a function of the spectral disparity in the ensemble, as a function of time, the number of atoms in the system, and as a function of the inter-pulse delay. We identify clear signatures of the enhanced cooperative dynamics for the pulse-driven inhomogeneous ensemble when dephasing in the dynamics of the ensemble is suppressed by a sufficient number of pulses during the individual emitter lifetime. These results demonstrate a post-fabrication tuning knob based on externally applied control fields for the dynamics of the many-emitter ensemble.
