A TIME-DEPENDENT CLASSICAL SOLUTION OF c=1 STRING FIELD THEORY AND NONPERTURBATIVE EFFECTS [PDF]
, 1992 We describe a real-time classical solution of c=1 string field theory written in terms of the phase space density, u(p, q, t), of the equivalent fermion theory.

A Variational Approach to Bound States in Quantum Field Theory
, 1993 We consider here in a toy model an approach to bound state problem in a nonperturbative manner using equal time algebra for the interacting field operators.

NONPERTURBATIVE EFFECTIVE ACTIONS OF (N=2)-SUPERSYMMETRIC GAUGE THEORIES [PDF]
International Journal of Modern Physics A, 1996 We elaborate on our previous work on (N=2)-supersymmetric Yang-Mills theory. In particular, we show how to explicitly determine the low energy quantum effective action for G=SU(3) from the underlying hyperelliptic Riemann surface, and calculate the leading instanton corrections.

ChemBioChem, Volume 26, Issue 22, November 17, 2025.Binding studies of α‐synuclein (αS) fibril ligands using photo‐crosslinking mass spectrometry and Förster resonance energy transfer show that the multiple system atrophy (MSA)‐selective lead, HY‐215, interacts with the αS C‐terminus, unlike Parkinson's disease (PD)‐selective lead, M503. Thus, often‐ignored interactions with the disordered regions of αS

The S-matrix bootstrap with neural optimizers. Part I. Zero double discontinuity
Journal of High Energy PhysicsIn this work, we develop machine learning techniques to study nonperturbative scattering amplitudes. We focus on the two-to-two scattering amplitude of identical scalar particles and study a toy model where we set the double discontinuity to zero ...

Infrared renormalon contributions in gluon TMD at small-x
Nuclear Physics B, 2020 The nonperturbative uncertainties from the infrared renormalons in the (color dipole) gluon distribution is estimated. It is shown that non-linear saturation effects at small-x shift the first IR pole at the Borel plane from 2/β2 to 1/β2.

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.

Laser‐Driven Charge‐Transfer Dynamics in the Quaterthiophene–Fullerene Donor/Acceptor Interface
ChemPhotoChem, Volume 9, Issue 11, November 11, 2025.This ab initio study investigates laser‐induced charge‐transfer in a quaterthiophene/fullerene complex at varying intensities of the external pulse. Pulses above 3 GW cm−2 are needed to trigger charge transfer, which is enabled by vibrations in the donor. Under stronger field intensities, transient effects in the system prevail.

Off-shell structure of the string sigma model
, 1999 The off-shell structure of the string sigma model is investigated. In the open bosonic string, nonperturbative effects are shown to depend crucially on the regularization scheme.

Stabilization of 2D Quantum Gravity by branching interactions [PDF]
, 1995 In this paper the stabilization of 2D quantum Gravity by branching interactions is considered. The perturbative expansion and the first nonperturbative term of the stabilized model are the same than the unbounded matrix model which define pure Gravity ...
