Abstract
We describe the screening properties of a three- and two-dimensional charged 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 determine the energies of the ground state and the excited states of charged particles screened by the Bose condensate as functions of the condensate density.
