Spin-charge Separation in Nodal Antiferromagnetic Insulator
Su-Peng Kou
In this paper, by using two dimensional (2D) Hubbard models with pi-flux phase and that on a hexagonal lattice as examples, we explore spin-charge-separated solitons in nodal antif…

Mutual Chern-Simons theory for Z_2 topological order
Su-Peng Kou, Michael Levin, Xiao-Gang Wen
We study several different topological ordered states in frustrated spin systems. The effective theories for those different Z_2 topological orders all have the same form --…
