Renormalization of divergent moment in probability theory
Ping Zhang, Wen-Du Li, Wu-Sheng Dai
Some probability distributions have moments, and some do not. For example, the normal distribution has power moments of arbitrary order, but the Cauchy distribution does not have p…
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…
