Title: Renormalons from Resurgence

Abstract: In this talk I will present recent results of M. Marino and I concerning the study of renormalons through the aid of the integrability, resurgence and simple Feynman diagrams. I will start by presenting a brief introduction of resurgence and renormalons. Then I will outline how they meet when exploring the asymptotic series of 1+1 QFTs and one-dimensional quantum many body systems. I will then relate our results to known non-perturbative phenomena, including superconductivity in one-dimensional fermions systems.
