Entropic uncertainty and quantum non-classicality of Unruh-Dewitt detectors in relativity
Yu-Kun Zhang, Li-Juan Li, Xue-Ke Song +2
An object moving with the acceleration will change the temperature of environment around it, because of the presence of the Unruh thermal effect. In this work, we investigate the i…
Spectral Bounds on Entropy and Ergotropy via Statistical Effective Temperature in Classical Polarization and Quantum Thermal States
Tariq Aziz, Meng-Long Song, Liu Ye +3
We formulate a unified definition of the statistical effective temperature (SET) for finite-dimensional classical and quantum systems using dimension-dependent indices of purity de…
Einstein-Podolsky-Rosen Steering Criterion and Monogamy Relation via Correlation Matrices in Tripartite Systems
Li-Juan Li, Xiao-Gang Fan, Xue-Ke Song +2
Quantum steering is considered as one of the most well-known nonlocal phenomena in quantum mechanics. Unlike entanglement and Bell non-locality, the asymmetry of quantum steering m…
Quantum battery in the Heisenberg spin chain models with Dzyaloshinskii-Moriya interaction
Xiang-Long Zhang, Xue-Ke Song, Dong Wang
Quantum battery (QB) is an energy storage and extraction device conforming to the principles of quantum mechanics. In this study, we consider the characteristics of QBs for the Hei…
Evaluating extractable work of quantum batteries via entropic uncertainty relations
Meng-Long Song, Xue-Ke Song, Liu Ye +1
In this study, we investigate the effectiveness of entropic uncertainty relations (EURs) in discerning the energy variation in quantum batteries (QBs) modelled by battery-charger-f…
