My current interests focus on the physics of the strong interactions at low energies, especially the phenomena of quark confinement and the spontaneous chiral magnetization of the vacuum. Because of the strongly nonlinear interactions among the underlying quarks and gluons these phenomena cannot be successfully treated using normal perturbation theory. My current research uses a discrete or lattice version of relativistic field theory to address these questions. In addition to providing new theoretical insights into continuum quantum field theory, lattice field theory allows the direct, systematic calculation of these nonperturbative phenomena. In particular, it is possible to predict many of the properties of systems of quarks and gluons, such as the masses and matrix elements of the strongly interacting particles (the proton, pion, rho, lambda, K, D, B, etc.) and the temperature and characteristics of the transition between normal hadronic matter and the quark-gluon plasma. In the future, we hope to be able to use similar techniques and the insight gained into the workings of nonabelian gauge theory to study weak interaction symmetry breaking and the Higgs-W-Z system.
At present we are carrying out a variety of these QCD calculations using a dedicated, 400-Gigaflops, parallel supercomputer completed here in the spring of 1998 and a 600-Gigaflops sister machine of the same design that we finished at Brookhaven in the summer of 1998. Together, these two machines provide state-of-the-art resources for numerical studies of quantum field theory.
