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

We study in detail the interplay between resurgent properties and the 1/N expansion in various integrable field theories with renormalons, where the perturbative series is factorially divergent even after restricting to a given order in 1/N. We focus on the free energy in the presence of a chemical potential coupled to a conserved charge, which can be computed exactly with the thermodynamic Bethe ansatz (TBA), as well as using large N QFT techniques.
