The path optimization for the sign problem of low dimensional QCD
Yuto Mori, Kouji Kashiwa, Akira Ohnishi
The path optimization has been proposed to weaken the sign problem which appears in some field theories such as finite density QCD. In this method, we optimize the integration path…
Evading the model sign problem in the PNJL model with repulsive vector-type interaction via path optimization
Akira Ohnishi, Yuto Mori, Kouji Kashiwa
We discuss the sign problem in the Polyakov loop extended Nambu--Jona-Lasinio model with repulsive vector-type interaction by using the path optimization method. In this model, bot…
Path optimization in 0+1 dimensional QCD at finite density
Yuto Mori, Kouji Kashiwa, Akira Ohnishi
We investigate the sign problem in 0+1 dimensional QCD at finite chemical potential by using the path optimization method. The SU(3) link variable is complexified to the SL(3,$\mat…
Application of the path optimization method to the sign problem in an effective model of QCD with a repulsive vector-type interaction
Kouji Kashiwa, Yuto Mori, Akira Ohnishi
The path optimization method is applied to a QCD effective model with the Polyakov loop and the repulsive vector-type interaction at finite temperature and density to circumvent th…
