Ground state energy density, susceptibility, and Wilson ratio of a two-dimensional disordered quantum spin system
J. -H. Peng, D. -R. Tan, F. -J. Jiang
A two-dimensional (2D) spin-1/2 antiferromagnetic Heisenberg model with a specific kind of quenched disorder is investigated, using the first principles nonperturbative quantum Mon…
Machine learning phases and criticalities without using real data for training
D. -R. Tan, F. -J. Jiang
We study the phase transitions of three-dimensional (3D) classical O(3) model and the two-dimensional (2D) classical XY model, as well as both the quantum phase transitions of 2D a…
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…
Applications of neural networks to the studies of phase transitions of two-dimensional Potts models
