Nature of the Quantum Phase Transition in Quantum Compass Model
Han-Dong Chen, Chen Fang, Jiangping Hu +1
In this work, we show that the quantum compass model on an square lattice can be mapped to a fermionic model with local density interaction. We introduce a mean-field approximation…
Topological Dirac Band Insulators in Three Dimensions and Novel Transport Laws
B. Andrei Bernevig, Han-Dong Chen
This paper has been withdrawn.
Quantitative Test of SO(5) Symmetry in the Vortex State of
Han-Dong Chen, Congjun Wu, Shou-Cheng Zhang
By numerically solving models with competing superconducting and antiferromagnetic orders, we study the magnetic field dependence of the antiferromagnetic moment in both the weak a…
Vortex configurations of bosons in an optical lattice
Congjun Wu, Han-dong Chen, Jiang-ping Hu +1
The single vortex problem in a strongly correlated bosonic system is investigated self-consistently within the mean-field theory of the Bose-Hubbard model. Near the superfluid-Mott…
