Phase Transition of the Ising model on a Hyperbolic Lattice
Takatsugu Iharagi, Andrej Gendiar, Hiroshi Ueda +1
The matrix product structure is considered on a regular lattice in the hyperbolic plane. The phase transition of the Ising model is observed on the hyperbolic lattice by m…
A Classical Background for the Wave Function Prediction in the Infinite System DMRG Method
Hiroshi Ueda, Andrej Gendiar, Tomotoshi Nishino
We report a physical background of the wave function prediction in the infinite system density matrix renormalization group (DMRG) method, from the view point of two-dimensional ve…
Tricritical point of J1-J2 Ising model on hyperbolic lattice
R. Krcmar, T. Iharagi, A. Gendiar +1
A ferromagnetic-paramagnetic phase transition of the two-dimensional frustrated Ising model on a hyperbolic lattice is investigated by use of the corner transfer matrix renormaliza…
Phase transition of clock models on hyperbolic lattice studied by corner transfer matrix renormalization group method
Andrej Gendiar, Roman Krcmar, Kouiji Ueda +1
Two-dimensional ferromagnetic N-state clock models are studied on a hyperbolic lattice represented by tessellation of pentagons. The lattice lies on the hyperbolic plane with a con…
Corner Transfer Matrix Renormalization Group Method Applied to the Ising Model on the Hyperbolic Plane
Kouji Ueda, Roman Krcmar, Andrej Gendiar +1
Critical behavior of the Ising model is investigated at the center of large scale finite size systems, where the lattice is represented as the tiling of pentagons. The system is on…
Modulation of Local Magnetization in two-dimensional Axial-Next-Nearest-Neighbor Ising model
Rene Derian, Andrej Gendiar, Tomotoshi Nishino
The axial next-nearest-neighbor Ising model is studied in two dimensions at finite temperature using the density matrix renormalization group. The model exhibits phase transition o…
Product Wave Function Renormalization Group: construction from the matrix product point of view
Kouji Ueda, Tomotoshi Nishino, Kouichi Okunishi +3
We present a construction of a matrix product state (MPS) that approximates the largest-eigenvalue eigenvector of a transfer matrix T, for the purpose of rapidly performing the inf…
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…
Stable Optimization of a Tensor Product Variational State
Andrej Gendiar, Nobuya Maeshima, Tomotoshi Nishino
We consider a variational problem for three-dimensional (3D) classical lattice models. We construct the trial state as a two-dimensional product of local variational weights that c…
Phase diagram of the 3D Axial-Next-Nearest-Neighbor Ising model
Andrej Gendiar, Tomotoshi Nishino
The three-dimensional axial-next-nearest-neighbor Ising (ANNNI) model is studied by a modified tensor product variational approach (TPVA). A global phase diagram is constructed wit…
Latent Heat Calculation of the 3D q=3, 4, and 5 Potts models by Tensor Product Variational Approach
Andrej Gendiar, Tomotoshi Nishino
Three-dimensional (3D) -state Potts models (=3, 4, and 5) are studied by the tensor product variational approach (TPVA), which is a recently developed variational method for…
