  As dipolar gases become more readily accessible in experiment there is a need
to develop a comprehensive theoretical framework of the few-body physics of
these systems. Here, we extend the coupled-pair approach developed for the
unitary two-component Fermi gas to a few-body system of dipolar bosons in a
spherical harmonic trap. The long range and anisotropy of the dipole-dipole
interaction is handled by a flexible and efficient correlated gaussian basis
with stochastically variational optimisation. We calculate the eigenenergy
spectrum and structural properties of two and three trapped bosonic dipoles.
This demonstrates the efficiency and flexibility of the coupled-pair approach
at dealing with systems with complex interactions.
