Resonance fluorescence in collective cavity QED

Abstract

We investigate the resonance fluorescence spectrum and photon correlations among its components of a system of A atoms interacting with a single mode of a quantized cavity field, using the SU(2) group representation technique and the approximate dynamical symmetry1 of the Dicke Model.

Resonance fluorescence from atoms in a cavity

A.S. Shumovsky, Tran Quang

We consider the problem of resonance fluorescence from N two-level atoms interacting with an intense cavity mode. The novel results for the spectral and statistical properties of the fluorescence field, which are quite different from collective resonance fluorescence in a free space, are obtained. The correlation, anti-correlation between spectrum components and violation of the Cauchy-Schwarz inequality are discussed.

The photon statistics of spectrum components and the cross correlation between spectrum components in resonance fluorescence are discussed. For the collective case anticorrelation between the central component and the sidebands is observed.

Photon correlations in the spectrum of a superradiant system in a strong cavity field

H. M. Castro-Beltrán, S. M. Chumakov, J. J. Sánchez-Mondragón

We investigate correlations among photons from the components of the resonance fluorescence spectrum of a cooperative system of two-level atoms interacting with a strong field of a single-mode lossless cavity. The properties of the central band are more closely related to the superradiant effect in free space than the sidebands. The central band field has reduced fluctuations and the collective dipole has its largest uncertainty when half the atoms are initially excited. Partial atomic excitation destroys the sub-Poissonian character of the sideband field and leads to a bunching-antibunching transition in the correlation of a sideband photon followed by a central band photon.

We investigate theoretically and experimentally spontaneous emission into the mode of a cavity QED system in the frequency domain. We show that the fluorescence spectrum differs significantly from the vacuum Rabi splitting.

Dissipative dynamics and superradiant countinuous time crystal in a Rydberg-interacting Dicke system

Haohang Zhou, Xianfeng Chen, Luqi Yuan

The interplay between many-body interactions and controlled dissipation provides a rich setting for nonequilibrium quantum phases. We explore the superradiant phase transitions in a Rydberg-interacting open Dicke model with cavity loss and local dissipation. We find that the nonlinear feedback from atomic interactions stabilizes the atomic collective excited state and induces resonant collective motion, which can be further converted into robust superradiant oscillations with the inclusion of local dissipation. Beyond the mean-field approximation, we prove this system can support the finite-size local dissipative temporal order, i.e., continuous time crystal, from evidences of the decreasing damping of a finite-frequency Liouvillian mode and the linear-size scaling of quantum fluctuations. The correlation between the atomic colletive dynamics and the cavity photon number makes our findings easy to detect from output optical signal. By bridging interacting atomic matter and driven-dissipative cavity QED, our Rydberg-interacting Dicke model provides a unique spin-1/2 platform for exploring dynamical phase transitions and macroscopic temporal order in open quantum matter.

Cavity QED with Collective Excitations of Warm, 3-Level Atoms

Garrett Hickman, T. B. Pittman, J. D. Franson

We derive a simplified Hamiltonian describing an ensemble of three-level room-temperature atoms in a two-mode cavity. If one transition is driven with a single photon, the ensemble behaves as if it were a single atom.
