Path optimization method with use of neural network for the sign problem in field theories
Akira Ohnishi, Yuto Mori, Kouji Kashiwa
We investigate the sign problem in field theories by using the path optimization method with use of the neural network. For theories with the sign problem, integral in the complexi…
Phase transition encoded in neural network
Kouji Kashiwa, Yuta Kikuchi, Akio Tomiya
We discuss an aspect of neural networks for the purpose of phase transition detection. To this end, we first train the neural network by feeding Ising/Potts configurations with lab…
Persistent homology analysis of deconfinement transition in effective Polyakov-line model
Takehiro Hirakida, Kouji Kashiwa, Junpei Sugano +3
The persistent homology analysis is applied to the effective Polyakov-line model on a rectangular lattice to investigate the confinement-deconfinement nature. The lattice data are…
Control the model sign problem via path optimization method: Monte-Carlo approach to QCD effective model with Polyakov loop
Kouji Kashiwa, Yuto Mori, Akira Ohnishi
We apply the path optimization method to a QCD effective model with the Polyakov loop at finite density to circumvent the model sign problem. The Polyakov-loop extended Nambu--Jona…
Anomalous Hall effect in dense QCD matter
Toshitaka Tatsumi, Ryo Yoshiike, Kouji Kashiwa
In this letter, we investigate the anomalous Hall effect in dense QCD matter. When the dual chiral density wave which is the spatially modulated chiral condensate appears in the me…
