Partial long-range order in antiferromagnetic Potts models
M. P. Qin, Q. N. Chen, Z. Y. Xie +5
The Potts model plays an essential role in classical statistical mechanics, illustrating many fundamental phenomena. One example is the existence of partially long-range-ordered st…
Partial order and finite-temperature phase transitions in Potts models on irregular lattices
Q. N. Chen, M. P. Qin, J. Chen +4
We evaluate the thermodynamic properties of the 4-state antiferromagnetic Potts model on the Union- Jack lattice using tensor-based numerical methods. We present strong evidence fo…
Plaquette order and deconfined quantum critical point in the spin-1 bilinear-biquadratic Heisenberg model on the honeycomb lattice
H. H. Zhao, Cenke Xu, Q. N. Chen +4
We have precisely determined the ground state phase diagram of the quantum spin-1 bilinear-biquadratic Heisenberg model on the honeycomb lattice using the tensor renormalization gr…
Renormalization of tensor-network states
H. H. Zhao, Z. Y. Xie, Q. N. Chen +3
We have discussed the tensor-network representation of classical statistical or interacting quantum lattice models, and given a comprehensive introduction to the numerical methods…
Second Renormalization of Tensor-Network States
Z. Y. Xie, H. C. Jiang, Q. N. Chen +2
We propose a second renormalization group method to handle the tensor-network states or models. This method reduces dramatically the truncation error of the tensor renormalization…
