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…
