Multi-dark-state resonances in cold multi-Zeeman-sublevel atoms [PDF]

open access: yes, 2006
We present our experimental and theoretical studies of multi-dark-state resonances (MDSRs) generated in a unique cold rubidium atomic system with only one coupling laser beam. Such MDSRs are caused by different transition strengths of the strong coupling

Topological phase separation in 2D hard-core Bose-Hubbard system away from half-filling [PDF]

open access: yes, 2003
We suppose that the doping of the 2D hard-core boson system away from half-filling may result in the formation of multi-center topological defect such as charge order (CO) bubble domain(s) with Bose superfluid (BS) and extra bosons both localized in ...
