Ising model on hyperbolic lattice studied by corner transfer matrix renormalization group method
Roman Krcmar, Andrej Gendiar, Kouji Ueda +1
We study two-dimensional ferromagnetic Ising model on a series of regular lattices, which are represented as the tessellation of polygons with p>=5 sides, such as pentagons (p=5),…
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…
