Ramp, Plateau, and Wormholes without Averaging, and Hyper-non-perturbative Structures in Gravity
Hong Liu
Universal hallmarks of quantum chaos---such as the ramp and plateau in the spectral form factor---and the ramp's gravitational duals involving wormholes are widely interpreted as c…

Breaking the degeneracy among regular black holes with gravitational lensing
Hong Liu, Xiaolong Liao, Yi Zhang
We examine parameter degeneracies in Culetu, Bardeen and Hayward regular black holes across lensing, shadow and quasinormal mode regimes. Our analysis reveals that while Einstein r…
