Borel and Stokes Nonperturbative Phenomena in Topological String Theory and c=1 Matrix Models [PDF]
, 2009 We address the nonperturbative structure of topological strings and c=1 matrix models, focusing on understanding the nature of instanton effects alongside with exploring their relation to the large-order behavior of the 1/N expansion.

How to define the moving frame of the Unruh-DeWitt detector on manifolds
Journal of High Energy PhysicsThe physical phenomena seen by an observer are defined for a local inertial system that is subjective to the observer. Such a coordinate system is called a “moving frame” because it changes from time to time.

Limits of TMD evolution in SIDIS at moderate Q
EPJ Web of Conferences, 2015 We investigate semi-inclusive deep inelastic scattering measurements in the region of relatively small Q, where sensitivity to nonperturbative transverse momentum dependence can dominate the evolution.

Elliptic genus derivation of 4d holomorphic blocks
Journal of High Energy Physics, 2018 We study elliptic vortices on ℂ × T 2 by considering the 2d quiver gauge theory describing their moduli spaces. The elliptic genus of these moduli spaces is the elliptic version of vortex partition function of the 4d theory. We focus on two examples: the

Nonperturbative scales in AdS/CFT
, 2009 49 pages, 1 figureInternational audienceThe cusp anomalous dimension is a ubiquitous quantity in four-dimensional gauge theories, ranging from QCD to maximally supersymmetric N=4 Yang-Mills theory, and it is one of the best investigated observables in ...

Dimensionally regularized study of nonperturbative quenched QCD [PDF]
, 1998 We study the dimensionally regularized fermion propagator Dyson-Schwinger equation in quenched nonperturbative QED in an arbitrary covariant gauge.

Reducible contributions to quantum electrodynamics in external fields
Journal of High Energy Physics, 2019 We consider one-particle reducible (1PR) contributions to QED and scalar QED processes in external fields, at one-loop and two-loop order. We investigate three cases in detail: constant crossed fields, constant magnetic fields, and plane waves.

Large-order behavior and nonperturbative effects [PDF]
Nuclear Physics B, 1995 Abstract We consider the energy-dependence of the large-order behavior of forward scattering amplitudes in theories having explicit mass parameters and instanton solutions. We show that in weak coupling theories the exponential part of the Espinosa-Ringwald type cross section can be determined by taking the minimum element of the perturbative series,
