Nonanalyticity, sign problem and Polyakov line in Z3-symmetric heavy quark model at low temperature: Phenomenological model analyses
Hiroaki Kouno, Kouji Kashiwa, Takehiro Hirakida
The nonanalyticity and the sign problem in the Z3-symmetric heavy quark model at low temperature are studied phenomenologically. For the free heavy quarks, the nonanalyticity is an…
Persistent homology analysis for dense QCD effective model with heavy quarks
Kouji Kashiwa, Takehiro Hirakida, Hiroaki Kouno
The isospin chemical potential region is known as the sign-problem free region of quantum chromodynamics (QCD). In this paper, we introduce the isospin chemical potential to the th…
Thermodynamics for SU(2) pure gauge theory using gradient flow
Takehiro Hirakida, Etsuko Itou, Hiroaki Kouno
We present the scale-setting function and the equation of state of the pure SU(2) gauge theory using the gradient flow method. We propose a reference scale t0 for the SU(2) gauge t…
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…
Themodynamics for pure SU() gauge theory using gradient flow
Takehiro Hirakida, Etsuko Itou, Hiroaki Kouno
We study the equation of state of pure SU() gauge theory using Monte Carlo simulations. The scale-setting of lattice parameters has been carried by using the gradient flow. We p…
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…
Interplay between sign problem and Z_3 symmetry in three-dimensional Potts model
Takehiro Hirakida, Hiroaki Kouno, Junichi Takahashi +1
We construct four kinds of Z3-symmetric three-dimentional (3-d) Potts models, each with different number of states at each site on a 3-d lattice, by extending the 3-d three-state P…
