Research Summary:

A new method, reduced Hamiltonian interpolation (RHI) combines dimensional interpolation with ideas from N-representability. This has provided promising results for a system of spinless bosons, predicting over 99% of the correlation energy. Current efforts are directed towards applying this methodology to more realistic interaction potentials in Bose-Einstein condensates and treating correlations of fermions.
