Electromagnetic emissions from near-horizon region of an extreme Kerr-Taub-Nut black hole
Fen Long, Songbai Chen, Jieci Wang +1
We have studied electromagnetic line emissions from near-horizon region in the extremal Kerr-Taub-NUT black hole spacetime and then probe the effects of NUT charge on the electroma…
Optimal estimation of parameters for scalar fields in expanding universe exhibiting Lorentz invariance violation
Xiaobao Liu, Zehua Tian, Jieci Wang +1
We address the optimal estimation of quantum parameters, in the framework of local quantum estimation theory, for a massive scalar quantum field in the expanding Robertson-Walker u…
Satellite-based quantum steering under the influence of spacetime curvature of the Earth
Tonghua Liu, Jiliang Jing, Jieci Wang
Spacetime curvature of the Earth deforms wavepackets of photons sent from the Earth to satellites, thus influencing the quantum state of light. We show that Gaussian steering of ph…
Radiative process of two entanglement atoms in de Sitter spacetime
Xiaobao Liu, Zehua Tian, Jieci Wang +1
We investigate the radiative processes of a quantum system composed by two identical two-level atoms in the de Sitter spacetime, interacting with a conformally coupled massless sca…
The influence of Unruh effect on quantum steering for accelerated two-level detectors with different measurements
Tonghua Liu, Jieci Wang, Jiliang Jing +1
We study the dynamics of steering between two correlated Unruh-Dewitt detectors when one of them locally interacts with external scalar field via different quantifiers. We find tha…
Synchronize accelerated clock in a multipartite relativistic quantum system
Li Zhang, Jiliang Jing, Heng Fan +1
We perform a protocol for multipartite quantum clock synchronization under the influence of Unruh thermal noise. The clocks consisting of Unruh-DeWitt detectors when one of detecto…
