Abstract
The zero-temperature, or quantum, metal-superconductor phase transition is studied in disordered systems in dimensions greater than 2. An effective local field theory is developed that keeps all soft modes or fluctuations explicitly. Renormalization group analysis on the resulting local field theory is then used to exactly determine the quantum critical behavior at this transition.
