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…
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…
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…
Exactly solvable Gross-Pitaevskii type equations
Yuan-Yuan Liu, Wen-Du Li, Wu-Sheng Dai
TWe suggest a method to construct exactly solvable Gross-Pitaevskii type equations, especially the variable-coefficient high-order Gross-Pitaevskii type equations. We show that the…
Bose-like few-fermion systems
Yu-Lin Zhao, Chi-Chun Zhou, Wen-Du Li +1
Dealing with a few-fermion system in the canonical ensemble, rather than in the grand canonical ensemble, shows that a few-fermion system with odd number fermions behaves different…
