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…
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 -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 -meson screening masses in both the confinement and the deconfinement region by using two-flavor…
Sign problem in -symmetric effective Polyakov-line model
Takehiro Hirakida, Junpei Sugano, Hiroaki Kouno +2
As an effective model corresponding to -symmetric QCD (-QCD), we construct a -symmetric effective Polyakov-line model (-EPLM) by using the logarithmic fermion e…
Properties of 2+1-flavor QCD in the imaginary chemical potential region: model prediction
Junpei Sugano, Hiroaki Kouno, Masanobu Yahiro
We study properties of 2+1-flavor QCD in the imaginary chemical potential region by using two approaches. One is a theoretical approach based on QCD partition function, and the oth…
Determination of hadron-quark phase transition line from lattice QCD and two-solar-mass neutron star observations
Junpei Sugano, Hiroaki Kouno, Masanobu Yahiro
We aim at drawing the hadron-quark phase transition line in the QCD phase diagram by using the two phase model (TPM) in which the entanglement Polyakov-loop extended Nambu--Jona-La…
