My primary research is on the ab initio many-body theory and statistical mechanics of very strongly correlated quantum fluids. This includes the helium fluids, low density electron many-body systems and low density quantum plasmas, all of which have properties that cannot be well described by traditional quantum many-body theories such as mean field, Landau theory, density functional theory, or dynamic mean field theory. The challenges are due to the very strong correlations between the particles in these systems. To understand the consequences of these strong correlations, we have been heavily involved in the development of Dynamic Many-Body Theory, which recently has been highly successful in accounting exceedingly well for inelastic neutron scattering from superfluid liquid helium four. This theory and these experiments have revealed a much richer multi-quasiparticle dynamics than previously known. The experiments have been near absolute zero and the theory at absolute zero. We are continuing our work to extend the theory to finite temperature, including the phase transition from a normal fluid to a superfluid in liquid helium four.
