Abstract
The properties of the Bose gas in traps have been experimentally and theoretically investigated. The main results of these investigations were discussed in L. Pitaevskii’s review. In this study, we consider excitations of low-lying levels in a disk-shaped magnetic trap. In contrast to the macrostructure, the excitation spectrum in the traps is a set of quasi-Bogolyubov modes with the gaps, which can be interpreted as a discrete breathing mode spectrum.
