Quantum criticality with emergent symmetry in the extended Shastry-Sutherland model
Wen-Yuan Liu, Xiao-Tian Zhang, Zhe Wang +3
Motivated by the novel phenomena observed in the layered material , the Shastry-Sutherland model (SSM) has been extensively studied as the minimal model for $\r…

Tensor network study of the spin-1/2 square-lattice -- model: incommensurate spiral order, mixed valence-bond solids, and multicritical points
Wen-Yuan Liu, Didier Poilblanc, Shou-Shu Gong +2
We use the finite projected entangled pair state (PEPS) method to investigate the global phase diagram of the spin-1/2 square-lattice -- antiferromagnetic (AFM) Heis…
