Initial tensor construction and dependence of the tensor renormalization group on initial tensors
Katsumasa Nakayama, Manuel Schneider
We propose a method to construct a tensor network representation of partition functions without singular value decompositions nor series expansions. The approach is demonstrated fo…

Initial tensor construction for the tensor renormalization group
Katsumasa Nakayama, Manuel Schneider
We propose a method to construct the initial tensor representation of partition functions and observables for the tensor renormalization group (TRG). The TRG is a numerical calcula…
