Quantum Oppenheimer-Snyder black hole evaporation and its fate
Hongwei Tan, Kui Xiao, Rong-zhen Guo +1
In this paper, we investigate the evaporation of the quantum Oppenheimer-Snyder black hole. Within a semiclassical framework, we compute the energy emission of Hawking radiation by…
Null infinity as Chern-Simons theories and its quantization
Hongwei Tan, Kui Xiao, Shoucheng Wang
This paper studies the quantization of the future null infinity () of an asymptotically flat spacetime. Based on the observation by Ashtekar and Speziale that $\math…
Massive particles tunneling from quantum Oppenheimer-Snyder black holes and black hole entropy
Hongwei Tan, Kui Xiao
In this paper, we investigate the tunneling process of massive scalar particles from a quantum Oppenheimer-Snyder black hole using the tunneling approach proposed by Parikh and Wil…
Generic Modified Teukolsky Formalism beyond General Relativity for Spherically Symmetric Cases
Rong-Zhen Guo, Hongwei Tan, Qing-Guo Huang
The observation of gravitational waves has inaugurated a new era for testing gravitational theories in strong-field, nonlinear regimes. Gravitational waves emit during the ringdown…
