Resurgence and Phase Transitions

Resurgence is a new approach to quantum field theory that combines perturbative and non-perturbative effects in a unified framework. I'll give an overview of the key ideas and discuss applications to phase transitions in physical problems. The main motivation is to find a new way to probe the QCD phase diagram. In this approach, a phase transition is interpreted as a change of dominant saddle in a path integral or partition function. Examples include the Ising model, chiral symmetry breaking in the Gross-Neveu model, the Thirring and Hubbard models, and the large N phase transition in 2d lattice gauge theory.
