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…
Symmetric Space-times from Thermodynamics
Jinbo Yang, Hongwei Tan, Tangmei He +1
We apply thermodynamics method to generate exact solution with maximum symmetric surface for Einstein equation without solving it. The exact solutions are identified with which peo…
Non-Markovian Entropy Dynamics in Living Systems from the Keldysh Formalism
Feiyi Liu, Min Guo, Hongwei Tan +1
Living systems are open nonequilibrium systems that continuously exchange energy, matter, and information with their environments, leading to stochastic dynamics with memory and ac…
On Coordinate Singularities Induced by Trapping Horizons
Jinbo Yang, Hongwei Tan, Hyat Huang +1
The trapping (or apparent) horizon serves as a key tool for tracing the complete evolution of black holes. We investigate a class of coordinate singularities induced by such trappi…
Black hole tunneling in loop quantum gravity
Hongwei Tan, Rong-Zhen Guo, Jingyi Zhang
In this paper, we investigate the Hawking radiation of the quantum Oppenheimer- Snyde black hole with the tunneling scheme by Parikh and Wilczek. We calculate the emission rate of…
Periodic orbits as probes of charged loop quantum gravity black holes through gravitational waves
Abolhassan Mohammadi, Arun Kumar, Hongwei Tan +1
Gravitational waves from extreme-mass-ratio inspirals (EMRI) provide a direct probe of the strong-field geometry of black holes. Motivated by this, we study the motion of test part…
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…
Starobinsky Inflation in k-Essence Framework: Attractor Dynamics, Reheating, and Consistency with ACT DR6
Abolhassan Mohammadi, Yogesh, Hongwei Tan +1
The recent ACT DR6 has shifted the preferred value of the scalar spectral index upward so that many well-established inflationary models have been disfavoured, including the Starob…
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…
Symmetry charges on reduced phase space and BMS algebra
Muxin Han, Zichang Huang, Hongwei Tan
This paper studies the reduced phase space formulation (relational formalism) of gravity coupling to the Brown-Kucha\v r dust for asymptotic flat spacetimes. A set of boundary cond…
The global monopole spacetime and its topological charge
Hongwei Tan, Jinbo Yang, Jingyi Zhang +1
In this paper, we show that the global monopole spacetime is one of the exact solutions of Einstein equations by means of the method treating the matter field as a non-linear sigma…
Effects of the inflaton mass on the pre-inflationary dynamics and primordial power spectra in loop quantum cosmology
Kui Xiao, Abolhassan Mohammadi, Hongwei Tan
Considering the mass parameters as free phenomenological parameters, we investigate inflation driven by a canonical scalar field with different potentials in LQC. We find that a sm…
