Excitation Spectra and Hard-core Thermodynamics of Bosonic Atoms In Double Well Optical Lattices
Bao Xu, Hong-Ye Wu, Yi-Cai Zhang +2
A general coupled representation is proposed for bosonic atoms in double well optical lattices. Based on such a representation, we investigate the excitation spectra and thermodyna…

Collinear to Anti-collinear Quantum Phase Transition by Vacancies
Bao Xu, Chen Fang, W. M. Liu +1
We study static vacancies in the collinear magnetic phase of a frustrated Heisenberg - model. It is found that vacancies can rapidly suppress the collinear antiferromagne…
