A Superradiant Gas of Driven-Dissipative Two-Level Atoms as a Source of Non-Classical Light — •Christopher Mink and Michael Fleischhauer — University of Kaiserslautern-Landau, Kaiserslautern, Germany
Motivated by the recent experimental observation of non-Gaussian correlations in the light emitted by a driven-dissipative cigar shaped cloud of two-level atoms [Ferioli et. al, arXiv:2311.13503] we theoretically investigate the dynamics and steady state properties of this system using a dissipative extension of the well-established Discrete Truncated Wigner Approximation. This allows us to determine the interatomic correlations as well as the radiated light field and its symmetrically ordered first and second order correlation functions g(1)(τ) and g(2)(τ). We verify a violation of the Siegert relation for the light emitted along the main axis of the cloud. Furthermore we show that in the steady state the atoms emit a negligible electric field which therefore does not contribute to the reduction of g(2)(τ). This is instead due to non-Gaussian statistics. Finally, the Wigner function of the radiated field is extracted and the quadratures are investigated to demonstrate generation of non-classical light.
