Topological chiral and nematic superconductivity by doping Mott insulators on triangular lattice
Yixuan Huang, D. N. Sheng
The mechanism of the unconventional topological superconductivity (TSC) remains a long-standing issue. We investigate the quantum phase diagram of the extended -- model…
Unconventional quantum phase transitions in a one-dimensional Lieb-Schultz-Mattis system
Wayne Zheng, D. N. Sheng, Yuan-Ming Lu
We study quantum phases and phase transitions in a one-dimensional interacting fermion system with a Lieb-Schultz-Mattis (LSM) type anomaly. Specifically, the inversion symmetry en…
Coexistence of non-Abelian chiral spin liquid and magnetic order in a spin-1 antiferromagnet
Yixuan Huang, W. Zhu, Shou-Shu Gong +2
We study the ground-state properties of a spin-1 Heisenberg model on a square lattice with the first- and second-nearest-neighbor antiferromagnetic couplings and and a…
Quantum Phases of Transition Metal Dichalcogenide Moiré Systems
Yiqing Zhou, D. N. Sheng, Eun-Ah Kim
Moiré systems provide a rich platform for studies of strong correlation physics. Recent experiments on hetero-bilayer transition metal dichalcogenide (TMD) Moiré systems are exciti…
Robust d-wave superconductivity in the square-lattice - model
Shoushu Gong, W. Zhu, D. N. Sheng
Unravelling competing orders emergent in doped Mott insulators and their interplay with unconventional superconductivity is one of the major challenges in condensed matter physics.…
Quantum Spin Liquid with Emergent Chiral Order in the Triangular-lattice Hubbard Model
Bin-Bin Chen, Ziyu Chen, Shou-Shu Gong +3
The interplay between spin frustration and charge fluctuation gives rise to an exotic quantum state in the intermediate-interaction regime of the half-filled triangular-lattice Hub…
