Abstract
We use the Bogoliubov-Hartree theory to describe low-energy excitation s of trapped Bose condensates. We construct the quasiparticle spectrum and the quasiparticle operators explicitly in terms of the bare atomi c operators. Our results reveal interesting properties of spatially co nfined Bose condensates and are in excellent agreement with recent exp eriments.
