Estimation of the magnetic critical exponent by Tensor Product Variational Approach
Andrej Gendiar, Tomotoshi Nishino, Rene Derian
A variational problem for three-dimensional (3D) classical lattice models is considered with trial state given by two-dimensional (2D) uniform product of local variational weights.…

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…
