Nonequilibrium and Nonperturbative Dynamics of Ultrastrong Coupling in Open Lines [PDF]

, 2013
The time and space resolved dynamics of a qubit with an Ohmic coupling to propagating 1D photons is studied, from weak coupling to the ultrastrong coupling regime.

Electroweak vacuum stability in the Higgs-Dilaton theory

Journal of High Energy Physics, 2017
We study the stability of the Electroweak (EW) vacuum in a scale-invariant extension of the Standard Model and General Relativity, known as a Higgs-Dilaton theory.

New nonperturbative scales and glueballs in confining supersymmetric gauge theories [PDF]

, 2018
We show that new nonperturbative scales exist in four-dimensional N $$ \mathcal{N} $$ = 1 super-Yang-Mills theory compactified on a circle, with an iterated-exponential dependence on the inverse gauge coupling.

The S-matrix bootstrap with neural optimizers. Part I. Zero double discontinuity

Journal of High Energy Physics
In 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 ...

Tadpole diagrams in constant electromagnetic fields

Journal of High Energy Physics, 2017
We show how all possible one-particle reducible tadpole diagrams in constant electromagnetic fields can be constructed from one-particle irreducible constant-field diagrams.

Nonperturbative evolution of parton quasi-distributions [PDF]

, 2017
Using the formalism of parton virtuality distribution functions (VDFs) we establish a connection between the transverse momentum dependent distributions (TMDs) F(x,k⊥2) and quasi-distributions (PQDs) Q(y,p3) introduced recently by X.

Nonperturbative QED vacuum birefringence

Journal of High Energy Physics, 2017
In this paper we represent nonperturbative calculation for one-loop Quantum Electrodynamics (QED) vacuum birefringence in presence of strong magnetic field.

Illustrated study of the semiholographic nonperturbative framework [PDF]

, 2017
Semiholography has been proposed as an effective nonperturbative framework which can consistently combine perturbative and nonperturbative effects for theories like QCD.

Quasiparticles in nonperturbative vacuum

, 2022
The model of nonperturbative vacuum in SU(2) Yang-Mills theory coupled to a nonlinear spinor field is suggested. By analogy with Abelian magnetic monopole dominance in quantum chromodynamics, it is assumed that the dominant contribution to such vacuum is

All-multiplicity amplitudes in impulsive PP-waves from the worldline formalism

Journal of High Energy Physics
We use the worldline formalism to derive Bern-Kosower type Master Formulae for the tree-level scattering of a charged particle and an arbitrary number of photons on impulsive PP-waves, where the coupling of the PP-wave to matter is treated fully non ...
