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.…
