Berezinskii-Kosterlitz-Thouless transition in lattice Schwinger model with one flavor of Wilson fermion
Yuya Shimizu, Yoshinobu Kuramashi
We have made a detailed study of the phase structure for lattice Schwinger model with one flavor of Wilson fermion on the plane. For numerical investigation, we develop a d…
Calculation of fermionic Green functions with Grassmann higher-order tensor renormalization group
Yusuke Yoshimura, Yoshinobu Kuramashi, Yoshifumi Nakamura +2
We develop calculational method for fermionic Green functions in the framework of Grassmann higher-order tensor renormalization group. The validity of the method is tested by apply…
Application of tensor network method to two dimensional lattice Wess-Zumino model
Ryo Sakai, Daisuke Kadoh, Yoshinobu Kuramashi +3
We study a tensor network formulation of the two dimensional lattice Wess-Zumino model with Wilson derivatives for both fermions and bosons. The tensor renormalizat…
Nucleon structure from 2+1 flavor lattice QCD near the physical point
Natsuki Tsukamoto, Ken-Ichi Ishikawa, Yoshinobu Kuramashi +2
We present an update on our results of nucleon form factors measured on a large-volume lattice at almost the physical point in 2+1 flavor QCD. The configurations a…
Continuum extrapolation of critical point for finite temperature QCD with Nf=3
Xiao-Yong Jin, Yoshinobu Kuramashi, Yoshifumi Nakamura +2
We study the critical point for finite temperature Nf=3 QCD using several temporal lattice sizes up to 10. In the study, the Iwasaki gauge action and non-perturbatively O(a) improv…
Mixed Precision Solver Scalable to 16000 MPI Processes for Lattice Quantum Chromodynamics Simulations on the Oakforest-PACS System
Taisuke Boku, Ken-Ichi Ishikawa, Yoshinobu Kuramashi +1
Lattice Quantum Chromodynamics (Lattice QCD) is a quantum field theory on a finite discretized space-time box so as to numerically compute the dynamics of quarks and gluons to expl…
