It is shown that the fidelity of the dynamically evolved system with its earlier time-density
matrix provides a signature of non-Markovian dynamics. Also, the fidelity associated with the …

Quantum parameter estimation is a crucial tool for inferring unknown parameters in physical
models from experimental data. The Jaynes–Cummings model is a widely used model in …

We propose a general formalism of a nonlinear Jaynes–Cummings-model by including
possible forms of nonlinearities of both the field and the intensity-dependent atom-field …

An exact density matrix of a phase-damped Jaynes-Cummings model (JCM) with entangled
Bell-like initial states formed from a model two-state atom and sets of adjacent photon …

This article concludes the special issue on Biosemiotic Entropy looking toward the future on
the basis of current and prior results. It highlights certain aspects of the series, concerning …

This review zeros in on the aspect of vaccine theory, practice, and research that is the most
dangerous, the most controversial, and that is at the epicenter of the alleged SARS-CoV-2 …

In this paper, by using the notion of negativity, we study the degree of entanglement of a two-
level atom interacting with a quantized radiation field, described by the Jaynes–Cummings …

We study in detail entanglement properties of the Jaynes–Cummings model assuming a two-
level atom (qubit) interacting with the first N levels of an electromagnetic field mode (qudit) in …

Using adiabatic approximation, a two arbitrary qubits Rabi model has been studied in ultra-
strong coupling. The analytical expressions of the eigenvalues and the eigenvalues are …

We study the partial transpose of the density operator to investigate entanglement between
a continuous-variable and a finite quantum system. In the framework of the soluble Jaynes …
