Reply to comments on "Gapless spin liquid ground state of spin-1/2 - Heisenberg model on square lattices"
Wen-Yuan Liu, Shaojun Dong, Chao Wang +4
In a recent comments [arXiv:1909.12788 (2019)], Zhao et al. argue that the definition of dimer orders used in our paper [Phys. Rev. B 98, 241109 (2018)] may not rule out valence bo…
Stable diagonal stripes in the t-J model at =1/8 doping from fPEPS calculations
Shao-Jun Dong, Chao Wang, Yong-Jian Han +2
We investigate the 2D t-J model at a hole doping of =1/8 using recently developed high accuracy fermionic projected entangled pair states(fPEPS) method. By applying stoc…
Gradient optimization of fermionic projected entangled pair states on directed lattices
Shao-Jun Dong, Chao Wang, Yongjian Han +2
The recently developed stochastic gradient method combined with Monte Carlo sampling techniques [PRB {\bf 95}, 195154 (2017)] offers a low scaling and accurate method to optimize t…
Gapless spin liquid ground state of spin-1/2 - Heisenberg model on square lattices
Wen-Yuan Liu, Shaojun Dong, Chao Wang +4
The spin-1/2 - Heisenberg model on square lattices are investigated via the finite projected entangled pair states (PEPS) method. Using the recently developed gradient op…
PEPS++: Towards Extreme-scale Simulations of Strongly Correlated Quantum Many-particle Models on Sunway TainhuLight
Lixin He, Hong An, Chao Yang +10
The study of strongly frustrated magnetic systems has drawn great attentions from both theoretical and experimental physics. Efficient simulations of these models are essential for…
