Determination of QCD phase diagram from the imaginary chemical potential region
Yuji Sakai, Kouji Kashiwa, Hiroaki Kouno +2
We test the reliability of the the Polyakov-loop extended Nambu-Jona-Lasinio (PNJL) model, comparing the model result with the lattice data at nonzero imaginary chemical potential.…
Roberge-Weiss phase transitions and extended Z3 symmetry
H. Kouno, Y. Sakai, K. Kashiwa +2
Using the Polyakov extended Nambu-Jona-Lasinio (PNJL) model with imaginary chemical potential, the relation between the Roberge-Weiss (RW) phase transition and the extended Z3 symm…
Vector-type four-quark interaction and its impact on QCD phase structure
Yuji Sakai, Kouji Kashiwa, Hiroaki Kouno +2
Effects of the vector-type four-quark interaction on QCD phase structure are investigated in the imaginary chemical potential region, by using the Polyakov-loop extended Nambu-Jona…
Correlations among discontinuities in QCD phase diagram
Kouji Kashiwa, Yuji Sakai, Hiroaki Kouno +2
We show, in general, that when a discontinuity of either zeroth-order or first-order takes place in an order parameter such as the chiral condensate, discontinuities of the same or…
Phase diagram in the imaginary chemical potential region and extended Z3 symmetry
Yuji Sakai, Kouji Kashiwa, Hiroaki Kouno +1
Phase transitions in the imaginary chemical potential region are studied by the Polyakov loop extended Nambu-Jona-Lasinio (PNJL) model that possesses the extended Z3 symmetry. The…
Polyakov loop extended NJL model with imaginary chemical potential
Yuji Sakai, Kouji Kashiwa, Hiroaki Kouno +1
The Polyakov loop extended Nambu--Jona-Lasinio (PNJL) model with imaginary chemical potential is studied. The model possesses the extended symmetry that QCD does.…
