A Neural Networks study of the phase transitions of Potts model
D. -R. Tan, C. -D. Li, W. -P. Zhu +1
Using the techniques of Neural Networks (NN), we study the three-dimensional (3D) 5-state ferromagnetic Potts model on the cubic lattice as well as the two-dimensional (2D) 3-state…

Validity of Harris criterion for two-dimensional quantum spin systems with quenched disorder
Jhao-Hong Peng, L. -W. Huang, D. -R. Tan +1
Inspired by the recent results regarding whether the Harris criterion is valid for quantum spin systems, we have simulated a two-dimensional spin-1/2 Heisenberg model on the square…

Universal scaling of three-dimensional dimerized quantum antiferromagnets on bipartite lattices
Deng-Ruei Tan, Fu-Jiun Jiang
Using the first principles quantum Monte Carlo (QMC) calculations, we investigate the previously established universal scaling between the Néel temperature and the staggered…
