Maxwell field with gauge fixing term in the radiation- and matter-dominant stages: exact solution and stress tensor
Xuan Ye, Yang Zhang
We study the Maxwell field with a general gauge fixing (GF) term in the radiation-dominant (RD) and matter-dominant (MD) stages of expanding Universe, as a continuation to the prev…
Maxwell field with gauge fixing term in de Sitter space: exact solution and stress tensor
Yang Zhang, Xuan Ye
The Maxwell field with a general gauge fixing (GF) term is nontrivial, not only the longitudinal and temporal modes are mixed up in the field equations, but also unwanted consequen…
Analytical Equation of Three-point Correlation Function of Galaxies: to Third Order of Density Perturbation
Shu-Guang Wu, Yang Zhang
Applying functional differentiation to the density field with Newtonian gravity, we obtain the static, nonlinear equation of the three-point correlation function of galaxies, t…
The nonlinear field equation of the three-point correlation function of galaxies
Shu-Guang Wu, Yang Zhang
Based on the field theory of density fluctuation under Newtonian gravity, we obtain analytically the nonlinear equation of 3-pt correlation function of galaxies in a homogeneou…
The nonlinear equation of correlation function of galaxies in the expanding universe and the solution in linear approximation
Yang Zhang, Bichu Li
We present an analytic study of the density fluctuation of a Newtonian self-gravity fluid in the expanding universe with , which extends our previous work in the static…
Field Equation of Correlation Function of Mass Density Fluctuation for Self-Gravitating Systems
Yang Zhang, Qing Chen
We study the mass density distribution of Newtonian self-gravitating systems. Modeling the system as a fluid in hydrostatical equilibrium, we obtain from first principle the field…
