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 ...

Fortschritte der Physik, Volume 74, Issue 3, March 2026.ABSTRACT We propose a manifestly duality‐invariant, Lorentz‐invariant, and local action to describe quantum electrodynamics in the presence of magnetic monopoles that derives from Sen's formalism. By employing field strengths as the dynamical variables, rather than potentials, this formalism resolves longstanding ambiguities in prior frameworks.

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.

Revisiting Coleman-de Luccia transitions in the AdS regime using holography
Journal of High Energy Physics, 2021 Coleman-de Luccia processes for AdS to AdS decays in Einstein-scalar theories are studied. Such tunnelling processes are interpreted as vev-driven holographic RG flows of a quantum field theory on de Sitter space-time.

Sequestering in String Compactifications
, 2010 We study the mediation of supersymmetry breaking in string compactifications whose moduli are stabilized by nonperturbative effects. We begin with a critical review of arguments for sequestering in supergravity and in string 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.

Advanced Science, Volume 13, Issue 2, 9 January 2026.A self‐consistent ab initio many‐body perturbation theory combined with locally exact dynamical mean field theory is employed to compute the sub‐bandgap electronic transitions in van der Waals antiferromagnets. The rich interplay between the magnetic ordering and spin‐entangled optical transitions, manifested as photoluminescence and absorption ...
