Quantum Statistics Forbids Particle Exchange Statistics beyond Bosons and Fermions in 3D
Chi-Chun Zhou, Shuai A. Chen, Yu-Zhu Chen +3
Quantum matter in three spatial dimensions is observed to consist exclusively of bosons and fermions. Whether this empirical fact follows from basic consistency requirements of qua…
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…
Converting Lattices into Networks: The Heisenberg Model and Its Generalizations with Long-Range Interactions
Chi-Chun Zhou, Yao Shen, Yu-Zhu Chen +1
In this paper, we convert the lattice configurations into networks with different modes of links and consider models on networks with arbitrary numbers of interacting particle-pair…
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…
Unified framework for generalized quantum statistics: canonical partition function, maximum occupation number, and permutation phase of wave function
Chi-Chun Zhou, Wu-Sheng Dai
Beyond Bose and Fermi statistics, there still exist various kinds of generalized quantum statistics. Two ways to approach generalized quantum statistics: (1) in quantum mechanics,…
Scalar scattering in Schwarzschild spacetime: Integral equation method
Wen-Du Li, Yu-Zhu Chen, Wu-Sheng Dai
An integral equation method for scalar scattering in Schwarzschild spacetime is constructed. The zeroth-order and first-order scattering phase shift is obtained.
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…
A 1+5-dimensional gravitational-wave solution: curvature singularity and spacetime singularity
Yu-Zhu Chen, Wen-Du Li, Wu-Sheng Dai
We solve a -dimensional cylindrical gravitational-wave solution of the Einstein equation, in which there are two curvature singularities. Then we show that one of the curvatur…
Scattering state and bound state of scalar field in Schwarzschild spacetime: Exact solution
Wen-Du Li, Yu-Zhu Chen, Wu-Sheng Dai
The main aim of this paper is twofold. (1) Exact solutions of a scalar field in the Schwarzschild spacetime are presented. The exact wave functions of scattering states and bound-s…
Why the entropy of spacetime is independent of species of particles -- the species problem
Yu-Zhu Chen, Wen-Du Li, Wu-Sheng Dai
The Hawking radiation emits all species of particles, but the Bekenstein-Hawking entropy is independent of the number of the species of particles. This is the so-called species pro…
Thermo field dynamics approach for entropy of spacetime
Yu-Zhu Chen, Wen-Du Li, Wu-Sheng Dai
A thermo field dynamics approach for calculating the entropy of a spacetime is suggested. It is exemplified through the Rindler spacetime, the Milne spacetime, the Boulware spaceti…
