Critical Point of a Symmetric Vertex Model
Kouji Ueda, Ryota Otani, Yukinobu Nishio +2
We study a symmetric vertex model, that allows 10 vertex configurations, by use of the corner transfer matrix renormalization group (CTMRG), a variant of DMRG. The model has a crit…

Snapshot Observation for 2D Classical Lattice Models by Corner Transfer Matrix Renormalization Group
K. Ueda, R. Otani, Y. Nishio +2
We report a way of obtaining a spin configuration snapshot, which is one of the representative spin configurations in canonical ensemble, in a finite area of infinite size two-dime…

Tensor Product Variational Formulation for Quantum Systems
Y. Nishio, N. Maeshima, A. Gendiar +1
We consider a variational problem for the two-dimensional (2D) Heisenberg and XY models, using a trial state which is constructed as a 2D product of local weights. Variational ener…
