Topological Solitons Seminar: Crossing boundaries: studying phases of gauge theories using strings

Presented by Kasper Peeters, Durham University

4 November 2008 14:15 in CLC407: Calman Learning Centre, Kingsley Barrett Lecture Theatre

In this talk, which should be accessible to non-specialists, I will
describe some of the excitement that is going on in the study of strongly coupled quantum field theories. Historically, much emphasis has been put on understanding quantum field theory using perturbative expansions of the partition sum. But what do we do when there are no small parameters available? Are we forced to abandon analytic control? In recent years, the so-called string/gauge theory correspondence has shown that there certainly are analytic methods to tackle such systems, but they are conceptually and technically totally different from what had been tried for decades. I will present an overview and
some aspects of my own recent work.
