Robust spin pseudogap and spin-charge separation in the - model
Zheng-Yuan Yue, Jia-Xin Zhang, Zheng-Cheng Gu
The - model, obtained from the usual - model by flipping the sign of the spin-down hopping term, has been proposed to eliminate the strong interference between doped h…
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…
Competing -wave pairing in overdoped - model
Wayne Zheng, Tao Cheng, Zheng-Yuan Yue +3
The -wave pairing symmetry has long been considered a defining feature of high-temperature superconductivity in cuprates. In this work, we reveal that -wave pairing states ex…
Revealing quantum phase string effect in doped Mott-insulator: a tensor network state approach
Wayne Zheng, Jia-Xin Zhang, Zheng-Yuan Yue +2
We apply the fermionic tensor network (TN) state method to understand the strongly correlated nature in a doped Mott insulator. We conduct a comparative study of the - mode…
Competing pair density wave orders in the square lattice - model
Wayne Zheng, Zheng-Yuan Yue, Jian-Hao Zhang +1
Over the last two decades, the competing orders in high- cuprates have been intensely studied, such as pseudogap phase, charge density waves (CDW), and pair density waves (P…
