Resurgence in Integrable Field Theories - Lecture 3
Offered By: Institut des Hautes Etudes Scientifiques (IHES) via YouTube
Course Description
Overview
Explore recent advancements in understanding resurgent properties of integrable field theories in two dimensions in this comprehensive lecture. Begin with a brief overview of Borel resummations and a historical perspective on the study of large order behavior in perturbation theory within quantum field theory. Delve into fundamental concepts of resurgence and their application to three well-known integrable field theories that are UV-free, develop mass gaps in the IR, allow for 1/N expansion, and exhibit renormalon singularities. Examine the interplay between resurgent properties and the 1/N expansion, focusing on the free energy observable in the presence of a chemical potential coupled to a conserved charge. Learn about exact computations using thermodynamic Bethe ansatz techniques and large N QFT methods, as well as results at finite N. This 2-hour and 18-minute lecture, delivered by Marco Serone from SISSA, Trieste, at the Institut des Hautes Etudes Scientifiques (IHES), offers an in-depth exploration of cutting-edge research in integrable field theories.
