The Tavis-Cummings model for more than one qubit interacting with a common oscillator
mode is extended beyond the rotating wave approximation (RWA). We explore the …

Knowledge of the relationships among different features of quantumness, like entanglement
and state purity, is important from both fundamental and practical viewpoints. Yet, this issue …

How to analytically deal with the general entanglement dynamics of separate Jaynes–
Cummings nodes with continuous-variable fields is still an open question, and few analytical …

In this article, we present the analytical solution for the pair of entangled two three-level
atoms in the cascade configuration with and without the atomic motion effect. The effects of …

How to analytically deal with the entanglement and coherence dynamics of separated
Jaynes–Cummings nodes with continuous-variable fields is still an open question. We here …

We study a chain of interacting individual quantum systems connected to heat baths at
different temperatures on both ends. Starting with the two-system case, we thoroughly …

The problem of the complete transfer of quantum states and entanglement in a four-qubit
system composed of two single-mode cavities and two two-level atoms is investigated. The …

In this paper, we propose a scheme to achieve selective population transfer in a Λ-type three-
level atomic system with a train of periodical Gaussian pulses. Based on temporal …

In this paper, we consider two separate Jaynes–Cummings (JC) nodes with a nonidentical
qubit-field system in the presence of dissipation terms. We reveal the influence of the time …

The link of two concepts, indistinguishability and entanglement, with the energy-time
uncertainty principle is demonstrated in a system composed of two strongly coupled bosonic …
