Title: Persistent subradiant correlations in a random driven Dicke model
Authors: Nikita Leppenen, Alexander N. Poddubny,
Abstract summary: We study theoretically the driven-dissipative dynamics of an array of two-level emitters, coupled to a single photonic mode, in the presence of disorder in the resonant frequencies.<n>We introduce the notion of subradiant correlations in the dynamics, corresponding to the eigenstates of the Liouvillian with a low decay rate, that can also oscillate in time.

Abstract: We study theoretically the driven-dissipative dynamics of an array of two-level emitters, coupled to a single photonic mode, in the presence of disorder in the resonant frequencies. We introduce the notion of subradiant correlations in the dynamics, corresponding to the eigenstates of the Liouvillian with a low decay rate, that can also oscillate in time. While the usual collective subradiant states do not survive the emitter resonant frequency fluctuations, these subradiant correlations are immune to such a type of disorder. These long-living correlations exist in finite-size systems, when their lifetime is parametrically longer than in the so-called Dicke time crystal phase.

Phenomenology of the Prethermal Many-Body Localized Regime [0.0]
Theory must now account for a large prethermal many-body localized (MBL) regime in which thermalization is extremely slow, but not completely arrested. We derive a quantitative description of these dynamics using a model of successive many-body resonances. Successive resonances may also underlie slow thermalization in strongly disordered systems in higher dimensions, or with long-range interactions.

Quantum chaos and thermalization in the two-mode Dicke model [77.34726150561087]
We discuss the onset of quantum chaos and thermalization in the two-mode Dicke model. The two-mode Dicke model exhibits normal to superradiant quantum phase transition. We show that the temporal fluctuations of the expectation value of the collective spin observable around its average are small and decrease with the effective system size.

Frequency combs with parity-protected cross-correlations from dynamically modulated qubit arrays [117.44028458220427]
We develop a general theoretical framework to dynamically engineer quantum correlations in the frequency-comb emission from an array of superconducting qubits in a waveguide. We demonstrate, that when the resonance of the two qubits are periodically modulated with a $pi$ phase shift, it is possible to realize simultaneous bunching and antibunching in cross-correlations of the scattered photons from different sidebands.

We report on the experimental investigation of the fluctuation properties in the resonance frequency spectra of a flat resonator. The cavity has the shape of a quarter bowtie billiard of which the corresponding classical dynamics is chaotic. We derive analytical expressions for statistical measures of short- and long-range correlations in such incomplete spectra.

We discuss how the time-delayed correlations can reveal information about the dynamics of the system. This enriched understanding of the system can trigger new experiments to probe nonlinear phenomena in optomechanics.
