The non-triviality of the vacuum in light-front quantization: An elementary treatment
- Physics
- 2018
It is often stated that the vacuum is trivial when light-front (null-plane) quantization is applied to a quantum field theory, in contrast to the situation with equal-time quantization. In fact, it…
Lightcone effective Hamiltonians and RG flows
- PhysicsJournal of High Energy Physics
- 2018
We present a prescription for an effective lightcone (LC) Hamiltonian that includes the effects of zero modes, focusing on the case of Conformal Field Theories (CFTs) deformed by relevant operators.…

Localisation in worldline pair production and lightfront zero-modes
- Physics
- 2014
A bstractThe nonperturbative probability of pair production in electric fields depending on lightfront time is given exactly by the locally constant approximation. We explain this by showing that the…
Gluon helicity flip in a plane wave background
- Physics, GeologyJournal of High Energy Physics
- 2019
A bstractWe compute the leading probability for a gluon to flip helicity state upon traversing a background plane wave gauge field in pure Yang-Mills theory and QCD, with an arbitrary number of…
Nonperturbative matching between equal-time and lightcone quantization
- PhysicsJournal of High Energy Physics
- 2020
We investigate the nonperturbative relation between lightcone (LC) and standard equal-time (ET) quantization in the context of λϕ4 theory in d = 2. We discuss the perturbative matching between bare…
Introduction to Lightcone Conformal Truncation: QFT Dynamics from CFT Data
- Physics
- 2020
We both review and augment the lightcone conformal truncation (LCT) method. LCT is a Hamiltonian truncation method for calculating dynamical quantities in QFT in infinite volume. This document is a…
Pair production in laser fields : finite size effects
- Physics
- 2010
We discuss pair creation in a strong laser background, using lightfront field theory. We show that all the physics is contained in the lightfront momentum transfer from the laser, and probe, to the…
Cancellation of Glauber gluon exchange in the double Drell-Yan process
- Physics
- 2016
A bstractAn essential part of any factorisation proof is the demonstration that the exchange of Glauber gluons cancels for the considered observable. We show this cancellation at all orders for…

The Light-Cone Effective Potential
- Physics
- 2002
It is shown how to calculate simple vacuum diagrams in light-cone quantum field theory. As an application, I consider the one-loop effective potential of phi^4 theory. The standard result is…
Light cone nucleon wave function in the quark-soliton model

A b s t r a c t The light-cone wave function of the nucleon is calculated in the limit Nc → ∞ in the quark-soliton model inspired by the theory of the instanton vacuum of QCD. The technique of the…
