Physics and Astronomy Colloquium

Wednesday, February 11th 2009
3:35 pm:
Speaker: Misha Shifman, University of Minnesota
Subject: From superconductivity to quark confinement

I present a nontechnical review of current understanding of the phenomenon of color confinement: from the conceptual roots of the idea related to Abrikosov vortices in superconductors to modern implementations of the dual Meissner effect in non-Abelian theories similar to quantum chromodynamics, the theory of hadrons. Supersymmetry was instrumental in recent developments. Efforts aimed at solving various aspects of QCD basing on supersymmetry and string-inspired ideas bring fruits. In a remarkable entanglement, theoretical constructions of the 1970s and 1990s combine with today's ideas to provide new insights.
