Dyson-Schwinger Equations with a Parameterized Metric
Wei Yuan, Si-xue Qin, Huan Chen +1
We construct and solve the Dyson-Schwinger equation (DSE) of quark propagator with a parameterized metric, which connects the Euclidean metric with the Minkowskian one. We show, in…
Chemical potential and the gap equation
Huan Chen, Wei Yuan, Lei Chang +3
In general the kernel of QCD's gap equation possesses a domain of analyticity upon which the equation's solution at nonzero chemical potential is simply obtained from the in-vacuum…
Dyson-Schwinger Equation and Quantum Phase Transitions in Massless QCD
Wei Yuan, Huan Chen, Yu-xin Liu
We study the stability of the highest symmetric solution (Wigner-solution) of Dyson-Schwinger equations in chiral limit and at zero temperature. Our results confirm that if the che…
Relation Between Chiral Susceptibility and Solutions of Gap Equation in Nambu--Jona-Lasinio Model
Yue Zhao, Lei Chang, Wei Yuan +1
We study the solutions of the gap equation, the thermodynamic potential and the chiral susceptibility in and beyond the chiral limit at finite chemical potential in the Nambu--Jona…
Classical Nature of the Evolution of Dark Energy Density
Wei Yuan, Yu-xin Liu
By ignoring the local density fluctuations, we construct an uniform Higgs-field's (inflaton's) quantum theory with varying effective Planck constant ($\hbar_{v}(t) \propto R(t)^{-3…
Chemical Potential Dependence of Chiral Quark Condensate in Dyson-Schwinger Equation Approach of QCD
Lei Chang, Huan Chen, Bin Wang +2
We propose a chemical potential dependent effective gluon propagator and study the chiral quark condensate in strongly interacting matter in the framework of Dyson-Schwinger equati…
