Self-congruent point in critical matrix product states: An effective field theory for finite-entanglement scaling
Jan T. Schneider, Atsushi Ueda, Yifan Liu +3
We set up an effective field theory formulation for the renormalization flow of matrix product states (MPS) with finite bond dimension, focusing on systems exhibiting finite-entang…
Finite-size and finite bond dimension effects of tensor network renormalization
Atsushi Ueda, Masaki Oshikawa
We propose a general procedure for extracting the running coupling constants of the underlying field theory of a given classical statistical model on a two-dimensional lattice, com…
Tensor Network Renormalization Study on the Crossover in Classical Heisenberg and Models in Two Dimensions
Atsushi Ueda, Masaki Oshikawa
We study the classical two-dimensional and Heisenberg models, using the Tensor-Network Renormalization (TNR) method. The determination of the phase diagram of these…
Resolving the Berezinskii-Kosterlitz-Thouless transition in the 2D XY model with tensor-network based level spectroscopy
Atsushi Ueda, Masaki Oshikawa
Berezinskii-Kosterlitz-Thouless transition of the classical XY model is re-investigated, combining the Tensor Network Renormalization (TNR) and the Level Spectroscopy method based…
