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…
Basis-independent coherence and its distribution in de Sitter spacetime
Samira Elghaayda, Atta ur Rahman, Mostafa Mansour
Quantum coherence in curved spacetime offers a fresh window into the interplay between gravity, thermality, and quantum resources. While previous work has shown that Markovian evol…
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…
Performance of a Superconducting Quantum Battery
Samira Elghaayda, Asad Ali, Saif Al-Kuwari +3
Finding a quantum battery model that demonstrates a quantum advantage while remaining feasible for experimental production is a considerable challenge. Here, a superconducting quan…
