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…

Dimeric perylene-bisimide organic molecules: Application as a quantum battery

Samira Elghaayda, Mostafa Mansour

This work introduces a unified theoretical framework for quantum batteries (QBs) constructed from thermally equilibrated arrays of dimeric perylene bisimide (PBI) molecules. These…

Quantum obesity and steering ellipsoids for fermionic fields in dilaton black hole

Samira Elghaayda, M. Y. Abd-Rabbou, Mostafa Mansour

This paper investigates quantum obesity (QO), quantum discord (QD), and the quantum steering ellipsoid (QSE) for bipartite Gisin states subjected to Garfinkle-Horowitz-Strominger (…

Quantum correlations and metrological advantage among Unruh-DeWitt detectors in de Sitter spacetime

Samira Elghaayda, Asad Ali, M. Y. Abd-Rabbou +2

A long-standing debate on Gibbons-Hawking (GH) decoherence centers on its unclear thermal nature. In this work, we investigate the robustness of quantum Fisher information (QFI) an…

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…
