Possibility of a Topological Phase Transition in Two-dimensional Model
Tsuyoshi Okubo, Naoki Kawashima
We study by large-scale Monte Carlo simulation the model, which can be regarded as an effective low-energy model of a triangular lattice Heisenberg antiferromagnet. vo…
TeNeS: Tensor Network Solver for Quantum Lattice Systems
Yuichi Motoyama, Tsuyoshi Okubo, Kazuyoshi Yoshimi +3
TeNeS (Tensor Network Solver) is a free/libre open-source software program package for calculating two-dimensional many-body quantum states based on the tensor network method and t…
Quantum critical phenomena in a spin-1/2 frustrated square lattice with spatial anisotropy
H. Yamaguchi, Y. Iwasaki, Y. Kono +7
We present a model compound with a spin-1/2 spatially anisotropic frustrated square lattice, in which three antiferromagnetic interactions and one ferromagnetic interaction are com…
Optimized Implementation for Calculation and Fast-Update of Pfaffians Installed to the Open-Source Fermionic Variational Solver mVMC
RuQing G. Xu, Tsuyoshi Okubo, Synge Todo +1
In this article, we present a high performance, portable and well templated implementation for computing and fast-updating Pfaffian and inverse of an even-ranked skew-symmetric (an…
