Theta vacuum and entanglement interaction in the three-flavor Polyakov-loop extended Nambu-Jona-Lasinio model
Takahiro Sasaki, Junichi Takahashi, Yuji Sakai +2
We investigate theta-vacuum effects on the QCD phase diagram for the realistic 2+1 flavor system, using the three-flavor Polyakov-extended Nambu-Jona-Lasinio (PNJL) model and the e…
Spontaneous parity and charge-conjugation violations at real isospin and imaginary baryon chemical potentials
Hiroaki Kouno, Mizuho Kishikawa, Takahiro Sasaki +2
The phase structure of two-flavor QCD is investigated at real isospin and imaginary quark chemical potentials by using the Polyakov-loop extended Nambu--Jona-Lasinio model. In the…
Nonlocal Polyakov-Nambu-Jona-Lasinio model and imaginary chemical potential
Kouji Kashiwa, Thomas Hell, Wolfram Weise
With the aim of setting constraints for the modeling of the QCD phase diagram, the phase structure of the two-flavor Polyakov-loop extended Nambu and Jona-Lasinio (PNJL) model is i…
Extensions and further applications of the nonlocal Polyakov--Nambu--Jona-Lasinio model
Thomas Hell, Kouji Kashiwa, Wolfram Weise
The nonlocal Polyakov-loop-extended Nambu--Jona-Lasinio (PNJL) model is further improved by including momentum-dependent wave-function renormalization in the quark quasiparticle pr…
Quark-mass dependence of the three-flavor QCD phase diagram at zero and imaginary chemical potential: Model prediction
Takahiro Sasaki, Yuji Sakai, Hiroaki Kouno +1
We draw the three-flavor phase diagram as a function of light- and strange-quark masses for both zero and imaginary quark-number chemical potential, using the Polyakov-loop extende…
Theta vacuum effects on QCD phase diagram
Yuji Sakai, Hiroaki Kouno, Takahiro Sasaki +1
Theta vacuum effects on the QCD phase structure in the μ-T plane are studied by using the Polyakov-loop extended Nambu-Jona-Lasinio model and its extension, where μis the quark che…
