Introduction to the Dicke Model: From Equilibrium to Nonequilibrium, and Vice Versa

P Kirton, MM Roses, J Keeling… - Advanced Quantum …, 2019 - Wiley Online Library
The Dicke model describes the coupling between a quantized cavity field and a large
ensemble of two‐level atoms. When the number of atoms tends to infinity, this model can …

-Phonon Bundle Emission via the Stokes Process

Q Bin, XY Lü, FP Laussy, F Nori, Y Wu - Physical review letters, 2020 - APS
We demonstrate theoretically the bundle emission of n strongly correlated phonons in an
acoustic cavity QED system. The mechanism relies on Stokes resonances that generate …

From integrability to chaos in quantum Liouvillians

A Rubio-García, R Molina, J Dukelsky - SciPost Physics Core, 2022 - scipost.org
The dynamics of open quantum systems can be described by a Liouvillian, which in the
Markovian approximation fulfills the Lindblad master equation. We present a family of …

Reconfigurable photon sources based on quantum plexcitonic systems

JB You, X **ong, P Bai, ZK Zhou, RM Ma, WL Yang… - Nano Letters, 2020 - ACS Publications
A single photon in a strongly nonlinear cavity is able to block the transmission of a second
photon, thereby converting incident coherent light into antibunched light, which is known as …

Critical phenomena and nonlinear dynamics in a spin ensemble strongly coupled to a cavity. II. Semiclassical-to-quantum boundary

M Zens, DO Krimer, S Rotter - Physical Review A, 2019 - APS
We numerically study the dynamics and stationary states of a spin ensemble strongly
coupled to a single-mode resonator subjected to loss and external driving. Employing a …

Collective dynamics of inhomogeneously broadened emitters coupled to an optical cavity with narrow linewidth

K Debnath, Y Zhang, K Mølmer - Physical Review A, 2019 - APS
We study collective effects in an inhomogeneously broadened ensemble of two-level
emitters coupled to an optical cavity with narrow linewidth. Using second-order mean-field …

Dicke model with disordered spin-boson couplings

P Das, S Wüster, A Sharma - Physical Review A, 2024 - APS
We introduce and study the disordered Dicke model in which the spin-boson couplings are
drawn from a random distribution with some finite width. Regarding the quantum phase …

Engineering dynamical photon blockade with Liouville exceptional points

Z Geng, Y Chen, Y Jiang, Y **a, J Song - Optics Letters, 2024 - opg.optica.org
We investigate the dynamical blockade in a nonlinear cavity and demonstrate the
connection between the correlation function g^(2)(t) and system parameters in the entire …

Comparison of the semiclassical and quantum optical field dynamics in a pulse-excited optical cavity with a finite number of quantum emitters

K Jürgens, F Lengers, D Groll, DE Reiter, D Wigger… - Physical Review B, 2021 - APS
The spectral and temporal response of a set of N quantum emitters embedded in a photonic
cavity is studied. Quantum mechanically, such systems can be described by the Tavis …

Periodic cavity state revivals from atomic frequency combs

M Zens, DO Krimer, HS Dhar, S Rotter - Physical Review Letters, 2021 - APS
Spin ensembles with a comb-shaped spectrum have shown exciting properties as efficient
quantum memories. Here, we present a rigorous theoretical study of such atomic frequency …
