Reservoir-independent lossless charging and protected storage of an open quantum battery
Asad Ali, H. Kuniyil, M. I Hussain +3
A quantum battery charged through a lossy intermediate state faces a structural trade-off between charging speed and dissipation. We show that an exact algebraic cancellation remov…
Coherence, Transport, and Chaos in 1D Bose-Hubbard Model: Disorder vs. Stark Potential
Asad Ali, M. I. Hussain, Saif Al-Kuwari +6
Quantum coherence and phase transitions are studied in a finite one-dimensional Bose--Hubbard model using exact diagonalization under thermal fluctuations, a Stark potential, and d…
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…
A cryogenic Paul trap for probing the nuclear isomeric excited state Th
Daniel Moritz, Kevin Scharl, Markus Wiesinger +16
While laser excitation of the nuclear isomeric transition in Th has been recently achieved for thorium atoms embedded in large-bandgap crystals, laser excitation and charac…
Controlled quantum secure remote sensing
Muhammad Talha Rahim, Saif Al-Kuwari, Mahmood Irtiza Hussain +1
Quantum resources enable secure quantum sensing (SQS) of remote systems, offering significant advantages in precision and security. However, decoherence in the quantum communicatio…
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…
