Physics Letters B, 1983
Abstract We show that the Parisi-Sourlas argument of dimensionality reduction by two in certain supersymmetric theories holds nonperturbatively, and that topological instanton configurations are important in three dimensions.

The Strength of Nonperturbative Effects in String Theory

, 1991
We argue that the leading weak coupling nonperturbative effects in closed string theories should be of order exp(— C/κ) where κ 2 is the closed string coupling constant. This is the case in the exactly soluble matrix models. These effects are in principle much larger than the exp(—C/κ 2 ) effects typical of the low energy field theory.

Nonperturbative Effects in Energy Correlators: From Characterizing Confinement Transition to Improving α_{s} Extraction.

Physical Review Letters
Energy correlators provide a powerful observable to study fragmentation dynamics in QCD. We demonstrate that the leading nonperturbative corrections for projected N-point energy correlators are described by the same universal parameter for any N, which ...

Nonperturbative effects in inner-shell ionization

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1984
Abstract A theoretical investigation of ion-induced inner-shell ionization is described, in which some physical effects that are nonperturbative in nature are included within the formalism of perturbation theory. In particular, the effects of the dynamical response of the outer electrons under the influence of the incident projectile are considered ...
