Sparse modeling study of extracting charmonium spectral functions from lattice QCD at finite temperature

Junichi Takahashi, Hiroshi Ohno, Akio Tomiya

We present charmonium spectral functions extracted from Euclidean-time correlation functions using sparse modeling (SpM). SpM solves inverse problems by considering only the sparsi…

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…

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…
