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…
Exact microscopic wave function for a topological quantum membrane
Shou-Cheng Zhang
The higher dimensional quantum Hall liquid constructed recently supports stable topological membrane excitations. Here we introduce a microscopic interacting Hamiltonian and presen…
Scaling properties of the projected SO(5) model in three dimensions
M. Jöstingmeier, A. Dorneich, E. Arrigoni +2
We study the scaling properties of the quantum ``projected'' SO(5) model in three dimensions by means of a highly accurate Quantum-Monte-Carlo analysis. Within the parameter regime…
Effective field theory description of the higher dimensional quantum Hall liquid
B. Andrei Bernevig, Chyh-Hong Chern, Jiang-Ping Hu +2
We derive an effective topological field theory model of the four dimensional quantum Hall liquid state recently constructed by Zhang and Hu. Using a generalization of the flux att…
Antiferromagnetism and hole pair checkerboard in the vortex state of high Tc superconductors
Han-Dong Chen, Jiang-Ping Hu, Sylvain Capponi +2
We propose a microscopic state for the vortex phase of BSCO superconductors. Around the vortex core or above H_{c2}, the d wave hole pairs form a checkerboard localized in the comm…
Tuning order in cuprate superconductors
Subir Sachdev, Shou-Cheng Zhang
This article presents our perspective on STM measurements by Hoffman et al. (cond-mat/0201348) of the vortex lattice in BSCCO. We discuss implications of these measurements for var…
