“Decoding the Path Integral”

Two of the biggest open problems in theoretical physics, the finite density "sign problem" and non-equilibrium physics in strongly interacting systems, require making sense of oscillatory path integrals. I will describe recent progress, based on the theory of "resurgent asymptotics", that has revealed surprising new structure in the path integral, connecting perturbative and non-perturbative physics. The new strategy is to construct steepest descent contours in the infinite dimensional space of configurations sampled by the path integral.
