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),…
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…
Least Action Principle for the Real-Time Density Matrix Renormalization Group
Kouji Ueda, Chenglong Jin, Naokazu Shibata +2
A kind of least action principle is introduced for the discrete time evolution of one-dimensional quantum lattice models. Based on this principle, we obtain an optimal condition fo…
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…
