Materials in which coulomb and spin interactions are significant, display a host of exotic phenomena such as superconductivity, magnetism, metal-insulator transitions, anomalous equations of state, and heavy-fermion behavior. These phenomena--all attributable to dynamical correlations among conduction electrons in representative materials-- currently comprise the frontier of modem condensed-matter theory and experiment; they represent the most fundamental of unsolved problems in the field. They illustrate how complex, scientifically rich, and technologically important effects can emerge when a large number of particles interact in a simple way. This research focused on the application of the National High Magnetic Field Laboratory at Los Alamos to the solution of these fundamental problems.
