Quantum discord and Fisher information for two-qubit system in the presence of thermal fields
AIP Advances, 2023 We consider a double Jaynes–Cummings model for a system of two atoms that interact with a radiation field defined in a thermal spin state. We examine the impact of the parameters of the quantum model on the temporal evolution of quantum discord, quantum ...

Hawking radiation as stimulated emission
Physics Letters B, 2020 We regard the Parikh-Wilczek's tunnelling model of Hawking radiation as a quantum mechanical process of stimulated emission. The hypothesized microstates are found seated at the horizon with double degeneracy. A Jaynes-Cummings toy model for a black hole

Thermal entanglement in a double Jaynes–Cummings model
Физика волновых процессов и радиотехнические системы, 2020 In this paper, we have investigated the entanglement dynamics between two initially entangled qubits interacting with two independent thermal cavities modes in the framework of resonant double JaynesCummings model.

Quantum Entanglement in Double Quantum Systems and Jaynes-Cummings Model
Nanoscale Research Letters, 2017 In the paper, we proposed a new approach to producing the qubits in electron transport in low-dimensional structures such as double quantum wells or double quantum wires (DQW).

A path integral for classical dynamics, entanglement, and Jaynes-Cummings model at the quantum-classical divide [PDF]
, 2010 The Liouville equation differs from the von Neumann equation 'only' by a characteristic superoperator. We demonstrate this for Hamiltonian dynamics, in general, and for the Jaynes-Cummings model, in particular. -- Employing superspace (instead of Hilbert

Entanglement and the factorization-approximation [PDF]
, 2001 For a bi-partite quantum system defined in a finite dimensional Hilbert space we investigate in what sense entanglement change and interactions imply each other.

Integrable Models of Interaction of Matter with Radiation [PDF]
, 2006 The simplified models of interaction of charged matter with resonance modes of radiation generalizing the well-known Jaynes-Cummings and Dicke models are considered. It is found that these new models are integrable for arbitrary numbers of dipole sources

Protecting, Enhancing and Reviving Entanglement
, 2012 We propose a strategies not only to protect but also to enhance and revive the entanglement in a double Jaynes-Cummings model. We show that such surprising features arises when Zeno-like measurements are performed during the dynamical ...

q-Boson in Quantum Integrable Systems [PDF]
, 2007 q-bosonic realization of the underlying Yang-Baxter algebra is identified for a series of quantum integrable systems, including some new models like two-mode q-bosonic model leading to a coupled two-component derivative NLS model, wide range of q ...
