Screening properties of a two-component charge Bose gas
The excitation spectrum of a two-component Bose-Einstein condensate has been discussed by Ref \cite{alex2comp} using the Bogoliubov equations. Here we make the additional contributions of the linear response function and dielectric function for a two-component CBG in the condensation phase as well as the confirmation of the plasmon excitation spectrum using the Gross-Pitaevskii (G-P) equations.
