Big bounce and black bounce in quasi-topological gravity
Yi Ling, Zhangping Yu
In the framework of quasi-topological (QT) gravity, we propose a novel model which is characterized by a bounce of the spacetime such that the singularity in standard general relat…
Gravity induced entanglement of multiple massive particles with large spin
Kai Li, Yi Ling, Zhangping Yu
We investigate the generation rate of the quantum entanglement in a system composed of multiple massive particles with large spin, where the mass of a single particle can be split…
The second-order quasi-normal modes for AdS black branes
Wen-Bin Pan, Zhangping Yu, Yi Ling
We investigate second-order gravitational perturbations in asymptotically AdS black branes, developing a gauge-invariant framework to compute the amplitude ratio between quadratic…
Symmetric black-to-white hole solutions with a cosmological constant
Zhong-Wen Feng, Qing-Quan Jiang, Yi Ling +2
For a system with a Hamiltonian constraint, we demonstrate that its dynamics is invariant under different choices of the lapse function, regardless of whether the Hamiltonian incor…
