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 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 fo…
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…
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 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 (…
Physically Accessible and Inaccessible Quantum Correlations of Dirac Fields in Schwarzschild Spacetime
Samira Elghaayda, Asad Ali, Saif Al-Kuwari +1
In this study, we investigate the influence of Hawking decoherence on the quantum correlations of Dirac fields between \textit{Alice} and \textit{Bob}. Initially, they share a \tex…
Distribution of distance-based quantum resources outside a radiating Schwarzschild black hole
Samira Elghaayda, Xiang Zhou, Mostafa Mansour
We obtain analytical expressions for distance-based quantum resources and examine their distribution in the proximity of a Schwarzschild black hole (SBH) within a curved background…
