Energy spectrum of interacting gas: cluster expansion method
Hao-Dan Li, Shi-Lin Li, Yu-Jie Chen +2
In this paper, we calculate the energy spectrum of interacting gases by converting the cluster expansion method in statistical mechanics into a method of solving energy eigenvalues…
Scattering approach for calculating one-loop effective action and vacuum energy
Yuan-Yuan Liu, Shi-Lin Li, Yu-Jie Chen +2
We propose an approach for calculating one-loop effective actions and vacuum energies in quantum field theory. Spectral functions are functions defined by the eigenvalues of an ope…
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…
Eliminating oscillation in partial sum approximation of periodic function
Shi-Lin Li, Yuan-Yuan Liu, Wen-Du Li +1
If we cannot obtain all terms of a series, or if we cannot sum up a series, we have to turn to the partial sum approximation which approximate a function by the first several terms…
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…
Cylindrical gravitational waves: radiation and resonance
Yu-Zhu Chen, Yu-Jie Chen, Shi-Lin Li +1
In the weak field approximation the gravitational wave is approximated as a linear wave, which ignores the nonlinear effect. In this paper, we present an exact general solution of…
Scalar field in Reissner-Nordström spacetime: Bound state and scattering state
Shi-Lin Li, Yuan-Yuan Liu, Wen-Du Li +1
In this paper, we solve the massive scalar field in the Reissner-Nordström spacetime. The scalar field in the Reissner-Nordström spacetime has both bound states and scattering stat…
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…
