Bright-state source cancellation in dissipative shortcut Raman atom optics

Asad Ali, Saif Al-Kuwari, M. I. Hussain +3

Spontaneous Raman scattering limits shortcut-assisted atom optics, but its microscopic origin is obscured once the lossy excited state is adiabatically eliminated. We organize the…

Magnetic Dipolar Quantum Battery with Spin-Orbit Coupling

Asad Ali, Samira Elghaayda, Saif Al-Kuwari +7

We investigate a magnetic dipolar system influenced by the -component of Zeeman splitting, Dzyaloshinsky--Moriya (DM) interaction, and Kaplan--Shekhtman--Entin-Wohlman--Aharony…

Quantum correlations versus spin magnitude: Transition to the classical limit

M. A. Yurischev, E. I. Kuznetsova, Saeed Haddadi

Quantum-classical transitions have long attracted much attention. We study such transitions in quantum spin-(,1/2) systems at thermal equilibrium. Unlike the previous work [Phys…

Quantum correlations in general qubit-qudit axially symmetric states

Saeed Haddadi, Elena I. Kuznetsova, M. A. Yurischev

The development and improvement of analytical methods for evaluating nonclassical correlations is one of the most important tasks in quantum information science. In this paper, we…

Kitaev Quantum Batteries: Super-Extensive Scaling of Ergotropy in 1D Spin Chain

Asad Ali, Samira Elghaayda, Saif Al-Kuwari +7

We investigate the performance of a novel model based on a one-dimensional (1D) spin- Heisenberg quantum chain, also known as 1D Kitaev chain, as a working medium…

Ergotropy and capacity optimization in Heisenberg spin-chain quantum batteries

Asad Ali, Saif Al-Kuwari, M. I. Hussain +5

This study examines the performance of finite spin quantum batteries (QBs) using Heisenberg spin models with Dzyaloshinsky-Moriya (DM) and Kaplan--Shekhtman--Entin-Wohlman--Aharony…
