Abstract
We use the Bogoliubov-Hartree theory to describe low-energy excitations of trapped Bose condensates. We construct the quasiparticle spectrum and the quasiparticle operators explicitly in terms of the bare atomic operators. Our results reveal interesting properties of spatially confined Bose condensates and are in excellent agreement with recent experiments.This publication has 0 references indexed in Scilit:
