We consider a relativistic charged particle in a background scalar field depending on both space and time. Poincaré, dilation and special conformal symmetries of the field generate conserved quantities in the charge motion, and we exploit this to generate examples of superintegrable relativistic systems. We also show that the corresponding single-particle wavefunctions needed for the quantum scattering problem can be found exactly, by solving the Klein–Gordon equation. 

High-intensity scaling in UV-modified QED

QED perturbation theory in a background field has been conjectured to break down for sufficiently high field intensity. The high-intensity behavior of a field theory is however intertwined with its

On rotationally invariant integrable and superintegrable classical systems in magnetic fields with non-subgroup type integrals

The aim of the present article is to construct quadratically integrable three dimensional systems in non-vanishing magnetic fields which possess so-called non-subgroup type integrals. The presence of

Self-force on a charged particle in an external scalar field

A charged particle subject to strong external forces will accelerate, and so radiate energy, inducing a self-force. This phenomenon remains contentious, but advances in laser technology mean we will

Superintegrable relativistic systems in spacetime-dependent background fields

We consider a relativistic charged particle in background electromagnetic fields depending on both space and time. We identify which symmetries of the fields automatically generate integrals

Covariant hamiltonian dynamics

We discuss the covariant formulation of the dynamics of particles with abelian and non-abelian gauge charges in external fields. Using this formulation we develop an algorithm for the construction of

Mode truncations and scattering in strong fields

Truncating quantum field theories to a dominant mode offers a nonperturbative approach to their solution. We consider here the interaction of charged scalar matter with a single mode of the

Exact Classical and Quantum Dynamics in Background Electromagnetic Fields.

By exploiting Poincaré symmetry and superintegrability, this work shows how to construct, and solve without approximation, new models of laser-matter interactions that improve predictions and analyses for experiments at intense laser facilities.

Superintegrable systems with position dependent mass

First order integrals of motion for Schrodinger equations with position dependent masses are classified. Eighteen classes of such equations with non-equivalent symmetries are specified. They include

Forms of Relativistic Dynamics

For the purposes of atomic theory it is necessary to combine the restricted principle of relativity with the Hamiltonian formulation of dynamics. This combination leads to the appearance of ten

Scattering on plane waves and the double copy

Perturbatively around flat space, the scattering amplitudes of gravity are related to those of Yang–Mills by colour-kinematic duality, under which gravitational amplitudes are obtained as the ‘double

It is shown that all four superintegrable quantum systems on the Euclidean plane possess the same underlying hidden algebra sl(3). The gauge-rotated Hamiltonians, as well as their integrals of
