Doped Mott Insulators in the Triangular Lattice Hubbard Model
Zheng Zhu, D. N. Sheng, Ashvin Vishwanath
We investigate the evolution of the Mott insulators in the triangular lattice Hubbard Model, as a function of hole doping in both the strong and intermediate coupling limits. U…

Spin-Orbital Density Wave and a Mott Insulator in a Two-Orbital Hubbard Model on a Honeycomb Lattice
Zheng Zhu, D. N. Sheng, Liang Fu
Inspired by recent discovery of correlated insulating states in twisted bilayer graphene (TBG), we study a two-orbital Hubbard model on the honeycomb lattice with two electrons per…

Hidden spin current in doped Mott antiferromagnets
Wayne Zheng, Zheng Zhu, D. N. Sheng +1
We investigate the nature of doped Mott insulators using exact diagonalization and density matrix renormalization group methods. Persistent spin currents are revealed in the ground…
