  • We study vacuum tunneling of non-Abelian gauge theory directly in Minkowski space. We do this by constructing a family of field configurations which connects vacuums of different winding numbers and which satisfies conditions necessary and sufficient to produce maximum tunneling amplitude. Using these explicit configurations we obtain explicitly the potential-energy barrier in winding-number space, through which tunneling occurs. We finally discuss the possible connections among the tunneling solution, the classical solution, and the full quantum-mechanical solution to the field equations.
  • Metal ions were extracted from pulsed discharge plasma operating in the transition region between vacuum spark and vacuum arc. At a peak current of about 4 kA, and with a pulse duration of 8 {mu}s, we observed mean ion charges states of about 6 for several cathode materials. In the case of platinum, the highest average charge state was 6.74 with charge states present as high as 10, and with gold we found traces of charge state 11. At higher currents, nonmetallic contaminants started to dominate the ion beam, preventing further enhancement of the metal charge states.
  • High resolution in situ imaging of metal surfaces during annealing and/or current transport is of great interest both for the application of metal lines in electronic devices and for extending our basic knowledge of the related complex physical phenomena. Due to its high resolution, the scanning tunneling microscope (STM) is a promising tool for in situ investigations of the structural changes of metals with respect to temperature (annealing) and current transport (electromigration). In this article, the instrumental modifications necessary for in situ scanning tunneling microscopy of heated and/or current carrying thin films under ultrahigh vacuum conditions are discussed. Using resultsmore » obtained on Ag films, the ability of the STM to image the surface dynamically is demonstrated, while structural changes induced by the current transport are taking place. 13 refs., 3 figs.« less
  • We study the variation of the phonon structure in the conductance curves of superconducting variable-barrier junctions formed using a scanning tunneling microscope. The observed vanishing of this structure as the tunneling barrier decreases is explained as a result of the mixing of electronic states in the Andreev reflection process, whose importance increases as the tunneling barrier decreases.
