Practical approach to the sign problem at finite theta-vacuum angle
Takahiro Sasaki, Hiroaki Kouno, Masanobu Yahiro
We investigate a way of circumventing the sign problem in lattice QCD simulations with a theta-vacuum term, using the PNJL model. We consider the reweighting method for the QCD Lag…
A simple model with Z_N symmetry
Masanobu Yahiro, Hiroaki Kouno, Yuji Sakai +2
We propose a simple model with the Z_N symmetry in order to answer whether the symmetry is a good concept in QCD with light quark mass. The model is constructed by imposing the fla…
Model approach to the sign problem on lattice QCD with theta vacuum
Takahiro Sasaki, Junichi Takahashi, Yuji Sakai +2
We propose a practical way of circumventing the sign problem in lattice QCD simulations with a theta-vacuum term. This method is the reweighting method for the QCD Lagrangian after…
Two-color QCD at imaginary chemical potential and its impact on real chemical potential
Kouji Kashiwa, Takahiro Sasaki, Hiroaki Kouno +1
We study properties of two-color QCD at imaginary chemical potential () from the viewpoint of the Roberge-Weiss (RW) periodicity, the charge conjugation and the pseudo-reality.…
A practical solution to the sign problem at finite theta-vacuum angle
Takahiro Sasaki, Hiroaki Kouno, Masanobu Yahiro
We propose a practical way of circumventing the sign problem in lattice QCD simulations with a theta-vacuum term. This method is the reweighting method for the QCD Lagrangian after…
Violations of parity and charge conjugation in the theta vacuum with imaginary chemical potential
Hiroaki Kouno, Yuji Sakai, Takahiro Sasaki +2
Charge conjugation (C) and Parity (P) are exact symmetries at theta =pi and Theta = mu/(iT)=pi, where theta is the parameter of the so-called theta-vacuum, mu is the imaginary quar…
