A Variational Sum-Rule Approach to Collective Excitations of a Trapped Bose-Einstein Condensate
arXiv:cond-mat/9803130 · doi:10.1143/JPSJ.68.1477
Abstract
It is found that combining an excitation-energy sum rule with Fetter's trial wave function gives almost exact low-lying collective-mode frequencies of a trapped Bose-Einstein condensate at zero temperature.
