Constructing effective action for gravitational field by effective potential method
Shi-Lin Li, Yu-Jie Chen, Yu-Zhu Chen +2
The aim of this paper is to construct a quantum effective action for gravitational fields by the effective potential method in quantum field theory. The minimum of the quantum effe…
Multipole moment and singular source in Newtonian gravity and in Einstein gravity
Yu-Zhu Chen, Yu-Jie Chen, Shi-Lin Li +1
The multipole moments are defined as the multipole expansion coefficients of the gravitational field at infinity. In Newtonian gravity, the multipole moments are determined by the…
Toy models of black hole, white hole and wormhole: thermal effects and information loss problem
Yu-Zhu Chen, Shi-Lin Li, Yu-Jie Chen +2
In this paper, by setting proper boundaries in the Minkowski spacetime, we construct three toy model spacetimes, a toy black hole, a toy white hole, and a toy wormhole. Based on th…
Quantum correction of gravitational constant
Yu-Jie Chen, Shi-Lin Li, Yu-Zhu Chen +2
We suggest a scheme for considering the quantum correction of the gravitational constant. In the model, the gravitational constant originates from a coupling of the gravitational f…
Gravitational wave scattering theory without large-distance asymptotics
Wen-Du Li, Shi-Lin Li, Yu-Jie Chen +2
In conventional gravitational wave scattering theory, a large-distance asymptotic approximation is employed. In this approximation, the gravitational wave is approximated by its la…
