The disordered Dicke model [PDF]
, 2023 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 transition we show that when the standard deviation $\sigma$ of the coupling ...

Dicke-Cooperativity-Assisted Ultrastrong Coupling Enhancement in Terahertz Metasurfaces
, 2022 A system of N two-level atoms cooperatively interacting with a photonic field can be described as a single giant atom coupled to the field with interaction strength ∝N. This enhancement, known as Dicke cooperativity in quantum optics, has recently become

Single-impurity-induced Dicke quantum phase transition in a cavity-Bose-Einstein condensate
Scientific Reports, 2017 We present a new generalized Dicke model, an impurity-doped Dicke model (IDDM), by the use of an impurity-doped cavity-Bose-Einstein condensate (BEC).

"Bound luminosity" state in the extended Dicke model [PDF]
, 2023 The extended Dicke model describes interaction of the single--mode electromagnetic resonator with an ensemble of interacting two--level systems. In this paper we obtain quasiclassical equations of motion of the extended Dicke model.

New Journal of Physics, 2015 In this paper, the finite-size Dicke model of arbitrary number of qubits is solved analytically in a unified way within extended coherent states. For the $N=2k$ or $2k-1$ Dicke models ( k is an integer), the G -function, which is only an energy dependent

The non-reciprocal Dicke model [PDF]
, 2023 We investigate the physics of an open two-component Dicke model, where the light field mediates non-reciprocal interactions between two spin species.

Critical behavior of quantum Fisher information in finite-size open Dicke model
AIP Advances, 2022 We explore the steady-state critical behavior of the finite-size open Dicke model—a model that incorporates spontaneous emission decay of the collective atomic spin states and decay of the cavity field. From the perspective of quantum information theory,

Dark matter and dark energy from a Kaluza–Klein inspired Brans–Dicke gravity with barotropic fluid
European Physical Journal C: Particles and Fields, 2022 We study the Kaluza–Klein inspired Brans–Dicke model with barotropic matter. Following from our previous work, the traditional Kaluza–Klein gravity action is introduced with an additional scalar field and 2 gauge fields.

Dicke model for quantum Hall systems
New Journal of Physics, 2016 In GaAs quantum Hall (QH) systems, electrons are coupled with nuclear spins through the hyperfine interaction, which is normally not strong enough to change the dynamics of electrons and nuclear spins.

Dicke States Generation via Selective Interactions in Dicke-Stark Model
, 2020 We propose a method to create selective interactions with Dicke-Stark model by means of time-dependent perturbation theory. By choosing the proper rotating framework, we find that the time oscillating terms depend on the number of atomic excitations and ...
