Nonperturbative Quantum Electrodynamics in the Cherenkov Effect [PDF]

open access: yesPhysical Review X, 2018
Quantum electrodynamics (QED) is one of the most precisely tested theories in the history of science, giving accurate predictions to a wide range of experimental observations. Recent experimental advances allow for the ability to probe physics on extremely short attosecond timescales, enabling ultrafast imaging of quantum dynamics.

Regularization in nonperturbative extensions of effective field theory

open access: yesPhysical Review D, 2022
The process of renormalisation in nonperturbative Hamiltonian Effective Field Theory (HEFT) is examined in the $Δ$-resonance scattering channel. As an extension of effective field theory incorporating the Lüscher formalism, HEFT provides a bridge between the infinite-volume scattering data of experiment and the finite-volume spectrum of energy ...

Quantum-induced trans-Planckian energy near horizon

open access: yesJournal 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.

Emergent symmetry in Brownian SYK models and charge dependent scrambling

open access: yesJournal 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.

Tunnelling of charged particles from black holes

open access: yesJournal of High Energy Physics, 2020
We state and explain the total rate at which a charged non-rotating black hole emits charged particles, taking into account both Hawking radiation and Schwinger pair production simultaneously.

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

open access: yesJournal 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]

open access: yes, 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.

Nonperturbative renormalization for 2PI effective action techniques [PDF]

open access: yesAnnals of Physics, 2005
Nonperturbative approximation schemes based on two-particle irreducible (2PI) effective actions provide an important means for our current understanding of (non-)equilibrium quantum field theory. A remarkable property is their renormalizability, since these approximations involve selective summations to infinite perturbative orders.
