Query: Correlation properties of a three-body bosonic mixture in a harmonic
  trap   We make use of a simple pair correlated wave function approach to obtain
results for the ground-state densities and momentum distribution of a
one-dimensional three-body bosonic system with different interactions in a
harmonic trap. For equal interactions this approach is able to reproduce the
known analytical cases of zero and infinite repulsion. We show that our results
for the correlations agree with the exact diagonalization in all interaction
regimes and with analytical results for the strongly repulsive impurity. This
method also enables us to access the more complicated cases of mixed
interactions, and the probability densities of these systems are analyzed.
