Beyond Boundaries: efficient Projected Entangled Pair States methods for periodic quantum systems
Shaojun Dong, Chao Wang, Hao Zhang +2
Projected Entangled Pair States (PEPS) are recognized as a potent tool for exploring two-dimensional quantum many-body systems. However, a significant challenge emerges when applyi…
A quantum spin liquid phase in the Kitaev-Hubbard model
Shaojun Dong, Hao Zhang, Chao Wang +3
The quantum spin liquid (QSL) state has been searched intensively in Kitaev-like materials, such as the Iridium oxides IrO and -RuCl. The half-filled Kitaev-Hubbard…
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…
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…
