Nonperturbative analysis of nuclear shape effects on the bound electron g factor [PDF]

Physical Review A, 2018
The theory of the g factor of an electron bound to a deformed nucleus is considered non-perturbatively and results are presented for a wide range of nuclei with charge numbers from Z=16 up to Z=98.

Quantum-induced trans-Planckian energy near horizon

Journal of High Energy Physics, 2018
We study the loop effects on the geometry and boundary conditions of several black hole spacetimes one of which is time-dependent and analyze the energy measured by an infalling observer near their horizons.

States of low energy in the Schwinger effect

Journal of High Energy Physics, 2023
States of low energy in cosmology minimise the energy density when smeared in a chosen time interval. We extend such construction to generic homogeneous (possibly anisotropic) particle creation settings.

Emergent symmetry in Brownian SYK models and charge dependent scrambling

Journal of High Energy Physics, 2022
In this work, we introduce a symmetry-based approach to study the scrambling and operator dynamics of Brownian SYK models at large finite N and in the infinite N limit.

Scattering amplitudes from dispersive iterations of unitarity

Journal of High Energy Physics, 2023
We present and numerically implement a computational method to construct relativistic scattering amplitudes that obey analyticity, crossing, elastic and inelastic unitarity in three and four spacetime dimensions.

Drell-Yan angular lepton distributions at small x from TMD factorization.

Journal of High Energy Physics, 2021
The Drell-Yan process is studied in the framework of TMD factorization in the Sudakov region s » Q 2 » q ⊥ 2 $$ {q}_{\perp}^2 $$ corresponding to recent LHC experiments with Q 2 of order of mass of Z-boson and transverse momentum of DY pair ∼ few tens ...

Instanton Corrections to Quark Form Factor at Large Momentum Transfer [PDF]

, 2002
Within the Wilson integral formalism, we discuss the structure of nonperturbative corrections to the quark form factor at large momentum transfer analyzing the infrared renormalon and instanton effects.
