Tunneling through ferromagnetic barriers on the surface of a topological insulator
Jinhua Gao, Wei-Qiang Chen, Xiao-Yong Feng +2
We study the transmission through single and double ferromagnetic barriers on the surface of a topological insulator. By adjusting the gate voltage and magnetization oreintation, t…

Topological characterization of quantum phase transitions in a S=1/2 spin model
Xiao-Yong Feng, Guang-Ming Zhang, Tao Xiang
We have introduced a novel Majorana representation of S=1/2 spins using the Jordan-Wigner transformation and have shown that a generalized spin model of Kitaev defined on a brick-w…

Gapped spin liquid states in a one-dimensional Hubbard model with antiferromagnetic exchange interaction
Jianhui Dai, Xiaoyong Feng, Tao Xiang +1
We study the phase diagram of a one-dimensional extended Hubbard model with antiferromagnetic exchange interaction analytically and numerically. The bosonization and transfer-matri…
