The Two Mysteries of Superconductivity

Materials Science Colloquium
Louis Taillefer, University of Sherbrooke, Canada
November 7, 2013 11:00AM to 12:00PM
Building 241
The Materials Science Colloquium will take place in the Energy Sciences Building (ESB 241), Room D172.

Superconductivity is a most remarkable property of matter, whereby electrons enter spontaneously a state of macroscopic quantum coherence in which electricity flows perfectly. Were this state sustainable at room temperature, our technological world would be profoundly transformed. The most promising materials are the copper oxides that remain superconducting halfway to room temperature. But two long standing puzzles have prevented scientists from understanding how this maximal temperature might be raised. The first is an enigmatic state called the pseudo-gap phase, which coexists with superconductivity and may compete with it. The second is the nature of the glue that binds electrons into Cooper pairs to form coherent superconductivity. In my talk, I will discuss recent experimental discoveries and present fresh ideas that shed new light on these two mysteries.
