Survival of nonclassical correlations in Lorentz-violating spacetime
Yangchun Tang, Zhilong Liu, Wentao Liu +1
The breakdown of Lorentz invariance, a potential signature of quantum gravity, offers a window into physics beyond general relativity. We investigate how such a violation, embodied…
Wormhole-Induced correlation: A Link Between Two Universes
Zhilong Liu, Wentao Liu, Xiaofang Liu +1
Motivated by the profound connection between quantum mechanics and spacetime geometry, particularly the conjectured correspondence between wormholes and quantum entanglement as pro…
Scrambling-Enhanced Quantum Battery Charging in Black Hole Analogues
Zhilong Liu, Ying Li, Zehua Tian +1
Black holes constitute nature's fastest quantum information scramblers, a phenomenon captured by gravitational analogue systems such as position-dependent XY spin chains. In these…
Can the latent signatures of quantum superposition be detected through correlation harvesting?
Yu Tang, Wentao Liu, Zhilong Liu +1
In this paper, we explore correlation harvesting in quantum superposition, specifically focusing on the entanglement and mutual information extracted by two Unruh-DeWitt detectors…
Harvesting correlations from BTZ black hole coupled to a Lorentz-violating vector field
Xiaofang Liu, Wentao Liu, Zhilong Liu +1
In this paper, we investigate the effects of Lorentz violation on correlations harvesting, specifically focusing on the harvested entanglement and harvested mutual information betw…
Simulation of the massless Dirac field in 1+1D curved spacetime
Zhilong Liu, Run-Qiu Yang, Heng Fan +1
Simulating the nature of quantum fields in diverse spacetime backgrounds offers valuable insights for the fundamental comprehension of quantum mechanics and general relativity. Her…
