Projected entangled pair states study of anisotropic-exchange magnets on triangular lattice
Meng Zhang, Chao Wang, Shaojun Dong +3
The anisotropic-exchange spin-1/2 model on a triangular lattice has been used to describe the rare-earth chalcogenides, which may have exotic ground states. We investigate the quan…
Simulation of the Ring-exchange Models with Projected Entangled Pair States
Chao Wang, Shaojun Dong, Yongjian Han +1
Algorithms to simulate the ring-exchange models using the projected entangled pair states (PEPS) are developed. We generalize the imaginary time evolution (ITE) method to optimize…
Bridging the Gap between Deep Learning and Frustrated Quantum Spin System for Extreme-scale Simulations on New Generation of Sunway Supercomputer
Mingfan Li, Junshi Chen, Qian Xiao +7
Efficient numerical methods are promising tools for delivering unique insights into the fascinating properties of physics, such as the highly frustrated quantum many-body systems.…
Calculation of Berry curvature using nonorthogonal atomic orbitals
Jin Gan, Daye Zheng, Lixin He
We present a derivation of the full formula to calculate the Berry curvature on non-orthogonal numerical atomic orbital (NAO) bases.Because usually, the number of NAOs is larger th…
First-principles study of magnetic structures of triangular antiferromagnets NaYbS and NaYbO
Da-Ye Zheng, Zhen-Xiong Shen, Meng Zhang +1
We investigate the magnetic interactions in triangular rare-earth delafossites materials NaYbO and NaYbS via first-principles calculations. The calculated Curie-Weiss tempe…
