HET Seminar | Clay Cordova, Institute for Advanced Study | Symmetries in Quantum Field Theory | PCTS, 407 Jadwin

Abstract:  Symmetry underlies the foundations of quantum field theory, defining concepts like particles and helping to organize their properties.  In this talk I will illustrate several modern topics in the study of symmetry including infinite-dimensional representations in conformal field theory, constraints of current algebra and energy conditions, and the interplay of symmetry and topology.   I will also describe how some of these techniques can be applied to understand Abelian gauge theories in 2+1 dimensions with time-reversal symmetry.
