Experiments will be carried out by Professor Van Harlingen to                   determine noise sources in ultrasmall area tunnel junctions and                 macroscopic quantum dynamics in Josephson superconductor devices.               Superconductor devices have served important functions as                       sensitive detectors and amplifiers for research.  Equally                       important, superconductor devices and thin film structures have                 proven to be valuable test systems for studying a wide range of                 important physical phenomena in condensed matter systems                        including quantum effects, localization, non-linear dynamics,                   chaos, phase transitions, and fluctuations.  Two problems in                    particular will be studied, discreet charge trapping                            fluctuations, which are a major source of low frequency noise and               will allow investigation of the kinetics and interactions of                    localized defect traps in amorphous materials, and quantum                      dynamics of macroscopic systems, which study will encompass the                 effect of dissipation on the evolution of quantum states and the                validity of quantum mechanics and quantum measurement theory to                 complex physical systems.
