AR2W01 - Physical resurgence: On quantum, gauge, and stringy

In this talk I will discuss what can be learned by extracting trans-series from the Bethe Ansatz integral equations. I will discuss the results of these techniques when applied to models such as non-relativistic Fermi gases, the O(N) sigma model and models with a topological theta angle. The physics of the results invokes superconductivity, instantons, and renormalons. The implication for renormalon physics will be left to Ramon’s talk.
