  1. Superconductor-metal quantum phase transition in nanowiresThomas Vojta, Missouri University of Science and Technology, DMR 0906566 • As a result of recent advances in nanotechnology, scientists can now produce tiny electronic devices such as ultrathin nanowires, which are only a few billionths of a meter wide. • Measurements reveal that sufficiently thick wires completely lose their electrical resistance at low temperatures, which is the hallmark of super- conductivity. Wires that are too narrow keep their resistance down to the lowest temperatures. • Vojta and coworkers developed a theoretical framework for calculating the resistivity in these wires and performed extensive computer simulations. • Nanoscale superconductors are fascinating laboratories for testing the fundamentals of quantum mechanics, and they are at the heart of the current quantum information revolution.
