Tensor-Network Population Annealing
Takumi Oshima, Yuma Ichikawa, Koji Hukushima
We propose a hybrid sampling method, tensor-network population annealing (TNPA), which combines tensor-network (TN) initialization with population annealing (PA). We apply this met…

Phase Transitions in a Modified Ising Spin Glass Model: A Tensor-Network-based Sampling Approach
Takumi Oshima, Yamato Arai, Koji Hukushima
Phase transitions in a modified Nishimori model, including the model considered by Kitatani, on a two-dimensional square lattice are investigated using a tensor-network-based sampl…

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,…
