Nonperturbative effects in a scalar supersymmetric theory
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.

Nonperturbative versus perturbative effects in generalized parton distributions [PDF]
Generalized parton distributions (GPDs) are studied at the hadronic (nonperturbative) scale within different assumptions based on a relativistic constituent quark model. In particular, by means of a meson-cloud model we investigate the role of nonperturbative antiquark degrees of freedom and the valence quark contribution.

Nonperturbative effects and the large-order behavior of matrix models and topological strings [PDF]
This work addresses nonperturbative effects in both matrix models and topological strings, and their relation with the large-order behavior of the 1/N expansion.

Determination of HQET nonperturbative matrix elements with renormalon subtraction using Fourier transform [PDF]
As higher order perturbative series are available, it is becoming necessary to include nonperturbative effects in QCD calculations using the OPE. In order to systematically determine nonperturbative effects and to incorporate them into theoretical ...

Nonperturbative effects and resurgence in Jackiw-Teitelboim gravity at finite cutoff [PDF]
We investigate the nonperturbative structure of Jackiw-Teitelboim gravity at finite cutoff, as given by its proposed formulation in terms of a $T\bar{T}$-deformed Schwarzian quantum mechanics.

Nonperturbative infrared effects for light scalar fields in de Sitter space [PDF]
We study the phi^4 scalar field theory in de Sitter space using the 2PI effective action formalism. This formalism enables us to investigate the nonperturbative quantum effects.

Nonperturbative QCD vacuum effects in nonlocal quark dynamics [PDF]
A straightforward calculation reveals the essentially nonlocal character of the leading heavy $Q\bar{Q}$ interaction arising from nonperturbative gluon field correlations in the model of a fluctuating QCD vacuum.
