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…

Cost Reduction of Swapping Bonds Part in Anisotropic Tensor Renormalization Group
Hideaki Oba
The bottleneck part of anisotropic tensor renormalization group (ATRG) is a swapping bonds part which consists of a contraction of two tensors and a partial singular value decompos…

Tensor Renormalization Group Algorithms with a Projective Truncation Method
Yoshifumi Nakamura, Hideaki Oba, Shinji Takeda
We apply the projective truncation technique to the tensor renormalization group (TRG) algorithm in order to reduce the computational cost from to , where is t…
