Newtonian potential from scattering amplitudes in super-renormalizable gravity
Haiyuan Feng, Rong-Jia Yang, Jinjun Zhang
Based on the classical limit of relativistic scattering amplitudes, we compute the coupling between a general super-renormalizable gravity and massive scalar particles. This allows…
The stability of the de-Sitter universe in nonlocal gravity
Haiyuan Feng, Rong-Jia Yang
We constructed the ghost-free condition for nonlocal gravity using de-Sitter background field expansion and identified the structure of the nontrivial form factors. Our analysis sh…
Thin accretion disk around black hole in Einstein-Maxwell-scalar theory
Yingdong Wu, Haiyuan Feng, Wei-Qiang Chen
We examine the accretion process in a thin disk surrounding a supermassive black hole within the framework of Einstein-Maxwell-scalar (EMS) gravity. Our investigation aims to eluci…
Adiabatic accretion onto black holes in Einstein-Maxwell-scalar theory
Haiyuan Feng, Miao Li, Gui-Rong Liang +1
We study the adiabatic accretion process of ordinary baryonic gas onto spherically symmetric black holes in Einstein-Maxwell-scalar theory, with two parameters and in the c…
Horizon thermodynamics in theory
Haiyuan Feng, Rong-Jia Yang
We investigate whether the new horizon first law still holds in theory. For this complicated theory, we first determine the entropy of black hole via Wald metho…
