Abstract

In supersymmetric theories, global symmetries are encoded geometrically as isometry groups of moduli spaces of vacua. A natural question is therefore whether generalised symmetries such as higher-form and higher-group symmetries understood in a similar manner. I will introduce a refinement of the moduli space of vacua that captures the existence of topological sectors in the infrared and come equipped with actions of generalised symmetries. This will be explored in the context of Higgs and Coulomb branches of 3d N = 4 supersymmetric gauge theories.


About the Speaker

Mathew Bullimore is currently an associate professor of Mathematical & Theoretical Particle Physics in the Department of Mathematical Sciences of Durham University in U.K. He received his DPhil from the University of Oxford in 2012 and held postdoctoral appointments at the Institute for Advanced Study, Perimeter Institute and the University of Oxford, before moving to Durham University in 2017.

His research centers on algebraic, geometric and topological structures in supersymmetric quantum field theory and applications to symmetries and dualities.
