Quantum solids, liquids, and gases program:Pedagogical introduction to multicomponent unconventional superconductors

by Prof. Daniel Agterberg (University of Wisconsin - Milwaukee)

Tuesday 27 Jul 2010, 15:00 → 16:15 Europe/Stockholm

This talk will discuss symmetry based Ginzburg-Landau theories for unconventional superconductors with an emphasis on multicomponent order parameters. This will begin with an introduction to the group theory needed for Ginzburg Landau theory. This will be followed by an overview of the derivation of the Ginzburg Landau phenomenological coefficients from weak-coupling BCS theory. The example of a p+ip spin-triplet superconductor will be discussed in detail.
