The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

The exciting new features of entanglement are burgeoning with revolutionary new advances
in the areas of quantum communication, quantum information processing and quantum …

Based on the deformed Heisenberg algebra, we propose a nonlinear Tavis–Cummings
model (TCM) which is obtained from the usual TCM by using deformed operators of a two …

The spectacular experimental results of the last few years in cavity quantum electrodynamics
and trapped-ion research has led to very-high-level laboratory performances. Such a …

In this work we examine a nonlinear version of the Jaynes–Cummings model for two
identical two-level atoms allowing for Ising-like and dipole–dipole interplays between them …

Exact solutions are obtained for a collective model of two identical two-level atoms
interacting with a quantized bimodal field with intensity-dependent coupling terms in a …

A new state of electromagnetic field is introduced. It is a type of the correlated two-mode
states but in finite dimensions. Based on the resonant ion–cavity interaction, we propose a …

Quantum Fisher information (QFI) and geometric phase have recently performed different
tasks in quantum information technology. We investigate the statistical quantities as the QFI …

We investigate a system of two identical and distinguishable spins 1/2, with a direct
magnetic dipole–dipole interaction, in an external magnetic field. Constraining the hyperfine …

We propose a scheme for generating a nonlinear finite-dimensional pair coherent state of
the vibrational motion of an ion in a two-dimensional trap. It is a type of the correlated two …
