Gravitational-Bumblebee perturbations: Exact decoupling and isospectrality
Hui-Fa Liu, Wentao Liu, Yu-Xiao Liu +2
In this paper, we present the exact decoupling of the full metric and bumblebee field perturbations in a Schwarzschild-like background. The coupled system reduces to four decoupled…
Macroscopic Optical Nonreciprocity: A Black Hole as an Optical Diode
Wentao Liu, Di Wu, Xiongjun Fang +2
Optical reciprocity--the principle that light retraces the same path when source and detector are interchanged--is a foundational concept in geometric optics. In this Letter, we de…
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…
Accelerating Black Hole Image Generation via Latent Space Diffusion Models
Ao Liu, Xudong Zhang, Lin Ding +3
Interpreting horizon-scale black hole images currently relies on computationally intensive General Relativistic Ray Tracing (GRRT) simulations, which pose a significant bottleneck…
Escape of quantum information across an analogue black hole horizon
Zhilong Liu, Wentao Liu, Zehua Tian +1
The complete evaporation of black holes, as a natural endpoint of Hawking radiation, gives rise to the black hole information paradox, which fundamentally challenges the principles…
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…
