Renormalised Amperean area for 2D Higgs-Yang-Mills Field

Dr Isao Sauzedde
(University of Warwick)
Abstract

The objective of the talk is to present elements of Euclidean Quantum Field Theory and of the Symanzik's polymer representation for a model which includes an interaction with a magnetic field. We will explain how the problem of constructing such an EQFT can be translated into the problem of renormalising the Amperean area of a planar Brownian motion, an object that we will introduce during the talk. No prerequisite knowledge of the topic is expected.
