Quantum effective actions from nonperturbative worldline dynamics [PDF]

open access: yesJournal of High Energy Physics, 2005
We demonstrate the feasibility of a nonperturbative analysis of quantum field theory in the worldline formalism with the help of an efficient numerical algorithm. In particular, we compute the effective action for a super-renormalizable field theory with

Density-functional tight binding meets Maxwell: unraveling the mysteries of (strong) light-matter coupling efficiently. [PDF]

open access: yesNanophotonics
Abstract Controlling chemical and material properties through strong light–matter coupling in optical cavities has gained considerable attention over the past decade. However, the underlying mechanisms remain insufficiently understood, and a significant gap persists between experimental observations and theoretical descriptions.

Nonperturbative effects of Topological Theta-term [PDF]

open access: green, 2011
We study the effects of a topological Theta-term on 2+1 dimensional principal chiral models (PCM), which are nonlinear sigma models defined on Lie group manifolds. We find that when Theta = pi, the nature of the disordered phase of the principal chiral model is strongly affected by the topological term: it is either a gapless conformal field theory, or

Determination of HQET nonperturbative matrix elements with renormalon subtraction using Fourier transform [PDF]

open access: yesEPJ Web of Conferences, 2022
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 ...

Infrared-safe energy weighting does not guarantee small nonperturbative effects [PDF]

open access: yesPhysical Review D, 2023
Infrared and collinear (IRC) safety has long been used a proxy for robustness when developing new jet substructure observables. This guiding philosophy has been carried into the deep learning era, where IRC-safe neural networks have been used for many ...

Nonperturbative effects and resurgence in Jackiw-Teitelboim gravity at finite cutoff [PDF]

open access: yesPhysical Review D, 2021
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.
