My current research centers on the properties of QCD systems at very high density. Such systems occur in high-energy heavy ion collisions and are also measured in high-energy (small x) deep inelastic lepton-proton scattering. Topics I have been particularly interested in are: (i) The relationship between unitarity limits and parton density limits (saturation); (ii) The maximal allowed occupation numbers for quarks and gluons in an hadronic wavefunction; (iii) First principles calculation of the approach to equilibration using a Boltzmann equation or(equivalently) classical Yang-Mills equations; (iv) The relationship between the factorial divergence of the QCD perturbation series and high field strength configurations. (v) The relationship between saturation phenomena in QCD and the reaction-diffusion processes in statistical physics.
