Holographic analysis of boundary correlation functions for the hyperbolic-lattice Ising model
Kouichi Okunishi, Tomotoshi Nishino
We analyze boundary spin correlation functions of the hyperbolic-lattice Ising model from the holographic point of view. Using the corner-transfer-matrix renormalization group (CTM…

Ferromagnetic Ising model on the hierarchical pentagon lattice
Takumi Oshima, Tomotoshi Nishino
Thermodynamic properties of the ferromagnetic Ising model on the hierarchical pentagon lattice is studied by means of the tensor network methods. The lattice consists of pentagons,…

Visualization of Entanglement Geometry by Structural Optimization of Tree Tensor Network
Toshiya Hikihara, Hiroshi Ueda, Kouichi Okunishi +2
In tensor-network analysis of quantum many-body systems, it is of crucial importance to employ a tensor network with a spatial structure suitable for representing the state of inte…
