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…
Fermi-Hubbard model on non-bipartite lattices: flux problem and emergent chirality
Wayne Zheng
On several one-dimensional (1D) and 2D nonbipartite lattices, we study both free and Hubbard interacting lattice fermions when some magnetic fluxes are threaded or gauge fields cou…
Quantum entanglement in the t-J chain: From charge-spin separation to recombination
Wayne Zheng, Zheng-Yu Weng
In contrast to the conventional von Neumann bipartite entanglement entropy (bEE), we show that a more appropriate description of the one-dimensional doped Mott insulator is a new k…
Chiral spin liquid with spinon Fermi surfaces in spin- triangular Heisenberg model
Shou-Shu Gong, Wayne Zheng, Mac Lee +2
We study the interplay of competing interactions in spin- triangular Heisenberg model through tuning the first- (), second- (), and third-neighbor () couplings.…
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…
Charge-spin mutual entanglement: A case study by exact diagonalization of the one hole doped - loop
Wayne Zheng, Zheng-Yu Weng
A doped Mott insulator exhibits peculiar properties associated with its singular sign structure. As a case study, we investigate the ground state and excitations of finite-size Hei…
Classification and Monte Carlo study of symmetric spin liquids on the triangular lattice
Wayne Zheng, Jia-Wei Mei, Yang Qi
We study different ways of symmetry fractionalization in spin liquids on the triangular lattice. Our classification can be used to identify the symmetry fractionalization i…
