Asymmetric quantum steering harvested near a Lorentz-violating BTZ black hole
Si-Yu Liu, Xin-Ze Song, Xiang-Yue Yu +3
We investigate the harvesting of quantum steering and its directional asymmetry between two Unruh-DeWitt detectors in a Lorentz-violating BTZ black hole spacetime. Since the detect…
Entanglement degradation of static black holes in effective quantum gravity
Xiaobao Liu, Wentao Liu, Shu-Min Wu
Quantum information science has been broadly explored in Einstein gravity and in various modified gravity theories; however, its extension to quantum gravity settings remains large…
Does the survival and sudden death of quadripartite steering in curved spacetime truly depend on multi-directionality?
Xiaobao Liu, Wentao Liu, Si-Han Shang +1
We systematically investigate the directional dependence of Gaussian quadripartite quantum steering and its redistribution among different modes in the background of a Schwarzschil…
Entangled Unruh-DeWitt detectors amplify quantum coherence
Shu-Min Wu, Yu-Xuan Wang, Wentao Liu
We explore the quantum coherence between a pair of entangled Unruh-DeWitt detectors, interacting with a quantum field, using a nonperturbative approach in a (3+1)-dimensional Minko…
Novel topological classes in black hole thermodynamics
Di Wu, Wentao Liu, Shuang-Qing Wu +1
By viewing black hole solutions as topological defects in thermodynamic parameter space, we unveil a novel topological class and two new topological subclasses, respectively denote…
Universal thermodynamic topological classes of rotating black holes
Xiao-Dan Zhu, Wentao Liu, Di Wu
In a recent study, Wei et al. [Phys. Rev. D 110, L081501 (2024)] proposed a universal classification scheme that interprets black hole solutions as topological defects within the t…
