Superfluidity and collective oscillations of trapped Bose-Einstein condensates in a periodical potential
arXiv:1107.4899 · doi:10.1140/epjd/e2012-30179-0
Abstract
Based on a unified theoretical treatment of the 1D Bogoliubov-de Genes equations, the superfluidity phenomenon of the Bose-Einstein condensates (BEC) loaded into trapped optical lattice is studied. Within the perturbation regime, an all-analytical framework is presented enabling a straightforward phenomenological mapping of the collective excitation and oscillation character of a trapped BEC where the available experimental configurations also fit.
