Dissertation findings appear in Nature Physics
30 June 2014
Yu Chen developed a novel way to fabricate superconducting nanocircuitry as part of his doctoral dissertation in the Goldman Superconductivity Research Group at the University of Minnesota.
Typically superconductivity and dissipation are thought to be mutually exclusive because dissipation, a process in thermodynamic systems whereby electric energy is transformed into heat, is a feature of a normal—versus a superconductive—state. Chen, along with his thesis adviser, Allen M. Goldman, and theoretical physicist Alex Kamenev, both of the University of Minnesota, spent years seeking an explanation for these extremely puzzling effects. "But we discovered that superconductivity and dissipation can coexist under rather generic conditions in what appears to be a universal manner," Chen said.
