Excitations and phase segregation in a two component Bose-Einstein condensate
preprint
posted on 2006-04-03, 10:24 authored by A.S. Alexandrov, V.V. KabanovBogoliubov-de Gennes (BdG) equations and the excitation spectrum of a twocomponent
Bose-Einstein condensate (BEC) are derived with an arbitrary interaction
between bosons, including long-range and short range forces. The
nonconverting BEC mixture segregates into two phases for some two-body
interactions. Gross-Pitaevskii (GP) equations are solved for the phase segregated
BEC. A possibility of boundary-surface and other localised excitations
is studied.
