Research Focus
Development of ab initio propagator methods in quantum chemistry and applications to chemical bonding and molecular spectra. Examples include new-generation self-energies that attain higher standards of accuracy, efficiency and interpretive lucidity and applications to molecules and ions with diffuse, delocalized electrons. These methods also have been applied to super-atomic species with very high or low electron binding energies and to multiply-charged, gas-phase anions. Dyson orbitals facilitate interpretations of accurate results in terms that build on familiar chemical concepts.
