Roberge-Weiss transitions at different center symmetry breaking patterns in a -QCD model
Xiu-Fei Li, Zhao Zhang
We study how the Roberge-Weiss (RW) transition depends on the pattern of center symmetry breaking using a -QCD model. We adopt flavor-dependent quark imaginary chem…
Dual meson condensates in the Polyakov-loop extended linear sigma model
Zhao Zhang, Haipeng Lu
Dual meson condensates as possible order parameters for deconfinement are investigated in a Polyakov-loop enhanced linear sigma model of QCD at both zero and finite isospin chemica…
Dual condensates at finite isospin chemical potential
Zhao Zhang, Qing Miao
The dual observables as order parameters for center symmetry are tested at finite isospin chemical potential in a Polyakov-loop enhanced chiral model of QCD with physical qua…
Fate of separate chiral transitions at finite under the influence of mismatched vector interactions
Zhao Zhang, Hai-Peng Su
The flavor-mixing induced by the mismatched vector-isoscalar and vector-isovector interactions at finite baryon chemical potential and isospin chemical potential is demon…
Correction to the Chiral Magnetic Effect from axial-vector interaction
Zhao Zhang
The recent lattice calculation at finite axial chemical potential suggests that the induced current density of the chiral magnetic effect (CME) is somehow suppressed comparing with…
Roles of axial anomaly on neutral quark matter with color superconducting phase
Zhao Zhang, Teiji Kunihiro
We investigate effects of the axial anomaly term with a chiral-diquark coupling on the phase diagram within a two-plus-one-flavor Nambu-Jona-Lasinio (NJL) model under the charge-ne…
Vector interaction, charge neutrality and multiple chiral critical point structures
Zhao Zhang, Teiji Kunihiro
We investigate the combined effect of the repulsive vector interaction and the positive electric chemical potential on the chiral phase transition by considering neutral color supe…
Another chiral critical end-point induced by neutral color superconductivity
Zhao Zhang, Kenji Fukushima, Teiji Kunihiro
This paper has been withdrawn by the authors, due to it's incompleteness.
Number of the QCD critical points with neutral color superconductivity
Zhao Zhang, Kenji Fukushima, Teiji Kunihiro
We investigate the effect of the electric-charge neutrality in equilibrium on the chiral phase transition by solving the chiral and diquark condensates in the two-flavor Nambu-…
2+1 Flavor Polyakov--Nambu--Jona-Lasinio Model at Finite Temperature and Nonzero Chemical Potential
Wei-jie Fu, Zhao Zhang, Yu-xin Liu
We extend the Polyakov-loop improved Nambu--Jona-Lasinio (PNJL) model to 2+1 flavor case to study the chiral and deconfinement transitions of strongly interacting matter at finite…
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…
Landau gauge condensates from global color model
Zhao Zhang, Wei-qin Zhao
We compute the dimension-2 gluon pair condensate and the dimension-4 mixed quark-gluon condensate in Landau gauge within the framework of global…
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…

Zhao Zhang, Wei-qin Zhao
We calculate the mixed tensor susceptibility of QCD vacuum in the framework of the global color symmetry model. In our calculation, the functional integration over gluon fields can…
Mixed Quark-Gluon condensate at finite temperature and density in the global color symmetry model
Zhao Zhang, Wei-Qin Zhao
The mixed quark-gluon condensate is another chiral order parameter in QCD, which plays an important role in the application of QCD sum rules. In this letter, we study the propertie…
