QCD-inequality analyses on pion condensate at real and imaginary isospin chemical potentials under finite imaginary quark chemical potential

Junpei Sugano, Hiroaki Kouno, Masanobu Yahiro

By employing QCD inequalities, we discuss appearance of the pion condensate for both real and imaginary isospin chemical potentials, taking also into account imaginary quark chemic…

Pion and $ρ$ -meson screening masses at finite chemical potential in two-flavor lattice QCD with Wilson fermion

Junpei Sugano, Junichi Takahashi, Hiroaki Kouno +1

We investigate the real and imaginary chemical-potential dependence of pion and $ρ$ -meson screening masses in both the confinement and the deconfinement region by using two-flavor…

Sign problem in $Z_{3}$ -symmetric effective Polyakov-line model

Takehiro Hirakida, Junpei Sugano, Hiroaki Kouno +2

As an effective model corresponding to $Z_{3}$ -symmetric QCD ( $Z_{3}$ -QCD), we construct a $Z_{3}$ -symmetric effective Polyakov-line model ( $Z_{3}$ -EPLM) by using the logarithmic fermion e…
