Abstract
The ground state of a binary boson mixture is represented by a spatially correlated Jastrow wave function and is optimally determined by minimizing the associated energy expectation value within hypernetted chain theory. We study formally the corresponding chemical potentials, volume coefficients, condensate densities, the exchange strength as well as the correlations between density — and concentration fluctuations, the momentum distributions and the exchange correlations associated with the Jastrow ground state. The formalism is specialized for dealing with foreign atoms immersed in Bose systems and is numerically applied to3He- and ↑H-impurities in liquid4He.
