We investigate two-species Bose gases in traps with various interactions using variational Quantum Monte Carlo (VMC) techniques at zero temperature. The bosons are represented by hard spheres (HS) whose diameter is equivalent to the s-wave scattering length in the low-energy and long-wavelength approximation. We explore the role of repulsive and attractive inter- or intraspecies interactions on the condensate properties of the mixtures, particularly the condensate fraction of each species as compared to the case when each species is in a separate trap of its own. We model the repulsive interactions by a hard core (HC) potential and the attractive interactions by a shallow model potential. The VMC density profiles and energies are evaluated at various interactions and two mass ratios of the species.
