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…
Topological Quantum Computation by Manipulating Quantum Tunneling Effect of the Toric Codes
Su-Peng Kou
Quantum computers are predicted to utilize quantum states to perform memory and to process tasks far faster than those of conventional classical computers. In this paper we show a…
Properties of A Class of Topological Phase Transition
Zi Cai, Shu Chen, Supeng Kou +1
The properties of a class of topological quantum phase transition (TQPT) are analyzed based on a model proposed by Haldane. We study the effect of finite temperature on this phase…
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 --…
