Abstract
We describe the screening properties of a three- and two-dimensional charge d Bose condensate within the random-phase approximation (RPA). The screened interaction for particles with opposite (attractive) and equal (repulsive) charges is calculated. Using the matrix diagonalization method we determin e the energies of the ground state and the excited states of charged partic les screened by the Bose condensate as functions of the condensate density.
