Superconductivity—Past, Present, and Future

Thursday, November 7, 2013 at 4:35pm to 5:50pm

Wright Lecture Hall, W201 110 North Professor Street, Oberlin, OH 44074

A Physics & Astronomy Department Lecture Series talk presented by Dr. Thomas Lemberger, professor of physics at the Ohio State University.

Abstract:  Superconductivity is a many-particle quantum ground state with zero electrical resistivity.  Discovered in 1911 in thin wires of Hg at 4 Kelvin, it was explained theoretically only after 46 years of effort.  The physics is broader than electrons in metals -- the concept of spontaneous symmetry breaking arose in the theory of superconductivity and lead directly to the “Higgs mechanism” for giving particles mass.  Practical applications include high-field magnets, fault-current limiters, electric filters for cell-phone repeaters, and levitated trains.  This talk will run through phenomenology of superconductors, underlying concepts, and present day research topics, including some of the research being done in Professor Lemberger's lab.

A reception for Professor Lemberger will begin at 4:10 p.m. in the Anderson Lounge—Wright Lab, second floor.
