All-mode Renormalization for Tensor Network with Stochastic Noise
Erika Arai, Hiroshi Ohki, Shinji Takeda +1
In usual (non-stochastic) tensor network calculations, the truncated singular value decomposition (SVD) is often used for approximating a tensor, and it causes systematic errors. B…
A novel method to evaluate real-time path integral for scalar theory
Shinji Takeda
We present a new scheme which numerically evaluates the real-time path integral for real scalar field theory in a lattice version of the closed-time formalism. First step of…
Triad second renormalization group
Daisuke Kadoh, Hideaki Oba, Shinji Takeda
We propose a second renormalization group (SRG) in the triad representation of tensor networks. The SRG method improves two parts of the triad tensor renormalization group, which a…
Nature of the phase transition for finite temperature QCD with nonperturbatively O() improved Wilson fermions at
Yoshinobu Kuramashi, Yoshifumi Nakamura, Hiroshi Ohno +1
We study the nature of the finite temperature phase transition for three-flavor QCD. In particular we investigate the location of the critical endpoint along the three flavor symme…
Investigation of complex theory at finite density in two dimensions using TRG
Daisuke Kadoh, Yoshinobu Kuramashi, Yoshifumi Nakamura +3
We study the two-dimensional complex theory at finite chemical potential using the tensor renormalization group. This model exhibits the Silver Blaze phenomenon in which bu…
Critical endpoint in the continuum limit and critical endline at of the finite temperature phase transition of QCD with clover fermions
Yoshifumi Nakamura, Yoshinobu Kuramashi, Hiroshi Ohno +1
We investigate the critical endpoints of the finite temperature phase transition of QCD at zero chemical potential. We employ the renormalization-group improved Iwasaki gauge actio…
