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…
The quarkynic phase and the Z_{Nc} symmetry
Yuji Sakai, Hiroaki Kouno, Takahiro Sasaki +1
We investigate the interplay between the Z_{Nc} symmetry and the emergence of the quarkyonic phase, adding the flavor-dependent complex chemical potentials μ_f=μ+iTθ_f with (θ_f)=(…
A QCD-like theory with the ZNc symmetry
Hiroaki Kouno, Yuji Sakai, Takahiro Makiyama +3
We propose a QCD-like theory with the ZNc symmetry. The flavor-dependent twisted boundary condition (TBC) is imposed on Nc degenerate flavor quarksin the SU(Nc) gauge theory. The Q…
