Important Contributions:
Pioneered (1961) ab initio quantum chemistry applications to small and large molecular systems,
with coding and free distribution of Hartree–Fock atomic and molecular programs.
First systematic estimate of correlation energy for atoms and molecules. Pioneering (1963)
density functionals methods for atoms and molecules, atomic and molecular relativistic correction,
graphics, and since 1972 Monte Carlo and Molecular Dynamics for liquids, biological systems
in aqueous solutions with ab initio potentials. Free distribution of Monte Carlo and Molecular Dynamic codes.
Pioneering (1983) parallel architecture with design and construction of LCAP1, LCAP2 and LCAP-3090
hardware and relative system software with applications to quantum chemistry, molecular dynamics,
and micro-dynamics. With G. Corongiu introduction and tests (2006-present) of
the Hartree–Fock–Heitler–London method and the Chemical Orbital model.
