Collective Shape-Phases of Interacting Fermion Systems
Yu-xin Liu, Zhan-feng Hou, Yu Zhang +1
A microscopic theory is presented for identifying shape-phase structures and transitions in interacting fermion systems. The method provides a microscopic description for collectiv…
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…
Coupling of pion condensate, chiral condensate and Polyakov loop in an extended NJL model
Zhao Zhang, Yu-Xin Liu
The Nambu Jona-Lasinio model with a Polyakov loop is extended to finite isospin chemical potential case, which is characterized by simultaneous coupling of pion condensate, chiral…
Dynamical chiral symmetry breaking and a critical mass
Lei Chang, Yu-Xin Liu, Mandar S. Bhagwat +2
On a bounded, measurable domain of non-negative current-quark mass, realistic models of QCD's gap equation can simultaneously admit two inequivalent dynamical chiral symmetry break…
Two-flavor QCD phases and condensates at finite isospin chemical potential
Zhao Zhang, Yu-xin Liu
We study the phase structure and condensates of two-flavor QCD at finite isospin chemical potential in the framework of a confining, Dyson-Schwinger equation model. We find that th…
Phase Transition of Finite Size Quark Droplets with Isospin Chemical Potential in the Nanbu--Jona-Lasinio Model
Guo-yun Shao, Lei Chang, Yu-xin Liu +1
Making use of the NJL model and the multiple reflection expansion pproximation, we study the phase transition of the finite size droplet with u and d quarks. We find that the dynam…
