Real-space construction and classification for time-reversal symmetric crystalline superconductors in 2D interacting fermionic systems
Yi-Ming Liu, Wei-Qiang Chen, Zheng-Cheng Gu
Crystalline symmetry and time-reversal symmetry are commonly present in real superconducting materials. However, the topological classification of systems respecting these symmetri…
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…
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…
Spin-charge separation and unconventional superconductivity in \textit{t}-\textit{J} model on honeycomb lattice
Jian-Jian Miao, Zheng-Yuan Yue, Hao Zhang +2
The physical nature of doped Mott-insulator has been intensively studied for more than three decades. It is well known that the single band Hubbard model or - model on the bi…
Emergent Symmetry in Quantum Phase Transitions: From Deconfined Quantum Critical Point to Gapless Quantum Spin Liquid
Wen-Yuan Liu, Shou-Shu Gong, Wei-Qiang Chen +1
The emergence of exotic quantum phenomena in frustrated magnets is rapidly driving the development of quantum many-body physics, raising fundamental questions on the nature of quan…
Chiral SO(4) spin-valley density wave and degenerate topological superconductivity in magic-angle-twisted bilayer-graphene
Chen Lu, Yongyou Zhang, Yu Zhang +6
Starting from a realistic extended Hubbard model for a -orbital tight-binding model on the Honeycomb lattice, we perform a thorough investigation on the possible electron…
