摘要：

We present a study for the dispersion relation and character of the excitations of a single- and two-component Bose-Einstein condensate (BEC). We study the single- component dispersion for a finite BEC system and look at examples of quasiparticles to understand and characterize the dispersion relation. Next we present the dispersion relation for a two-component BEC in both the miscible and immiscible parameter regimes. Then we present examples of the quasiparticles for both regimes.
