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.

Nonperturbative Effects on the String World Sheet (Ii)
Nuclear Physics B, 1987 We show that the space-time superpotential, which is known to receive no string theoretic corrections in finite orders in α′, is modified by world-sheet instantons. This has a number of interesting consequences for the physics of compactification schemes which lead to low-energy supersymmetry.

Multi‐Scale Structural Insights Into Amphiphilic Model PEG–PCL Co‐Networks From LS and SANS
Macromolecular Chemistry and Physics, Volume 227, Issue 7, 14 April 2026.We present a multiscale structural study of amphiphilic PEG–PCL co‐networks combining light scattering in THF and small‐angle neutron scattering in D2O. This dual‐solvent approach reveals how solvent quality, polymer volume fraction, and PEG/PCL interactions govern static and dynamic correlation lengths, network homogeneity, and nanoscale domain ...

Nonperturbative effects in QCD at finite temperature and density [PDF]
Physics of Particles and Nuclei, 1999 These lecture notes illustrate the application of Dyson-Schwinger equations in QCD. The extensive body of work at zero temperature and chemical potential is represented by a selection of contemporary studies that focus on solving the Bethe-Salpeter equation, deriving an exact mass formula in QCD that describes light and heavy pseudoscalar mesons ...

Exact local distribution of the absolutely continuous spectral measure
Proceedings of the London Mathematical Society, Volume 132, Issue 4, April 2026.Abstract It is well‐established that the spectral measure for one‐frequency Schrödinger operators with Diophantine frequencies exhibits optimal 1/2$1/2$‐Hölder continuity within the absolutely continuous spectrum (Avila and Jitomirskaya, Commun. Math. Phys. 301 (2011), 563–581).

Numerical study of multiparticle scattering in λϕ 4 theory
Journal of High Energy Physics, 2018 We study numerically classical collisions of waves in λϕ 4 theory. These processes correspond to multiparticle scattering in the semiclassical regime.

Helically Magnetized Plasma: From Photonic Fermi‐Arc Metal to Chirality‐Free Uniaxial Medium
Nanophotonics, Volume 15, Issue 5, 16 March 2026.A helically modulated magnetic field in magnetized plasma realizes a photonic Fermi‐arc metal, enabling full analytical tracking of Weyl node evolution. As modulation strengthens, opposing‐chirality Fermi arcs hybridize and recombine, yielding a chirality‐free uniaxial optical medium without conventional node annihilation.

Nonperturbative vacuum and hard scattering processes [PDF]
, 1980 A number of interesting suggestions for the QCD nonperturbative vacuum have been advocated in recent years by a group of people in Copenhagen. Some of the main ideas are briefly reviewed.

|Vub| determination and testing of lepton flavour universality in semileptonic Bc → D(∗) decays
Journal of High Energy Physics, 2020 In light of prospects for measurements of B c → D (∗) lv decays in the upcoming Upgrade II of the LHC, we show that by using calculated B c → D (∗) form factors a competitive extraction of the |V ub | CKM matrix element from the B c → Dμ v ¯ μ $$ {B}_c\

Merging van der Waals Materials and Optical Metasurfaces for Cavity Quantum Electrodynamics
Nanophotonics, Volume 15, Issue 5, 16 March 2026.Flat optical metasurfaces supporting quasi‐bound states in the continuum (qBIC) enable cavity‐like, high‐Q resonances in ultrathin nanostructures. This perspective explores the emergence of cavity quantum electrodynamics in qBIC metasurfaces, specifically those made from ultrathin van der Waals nanostructures, where cavities and emitters are seamlessly
