Upcoming and planned experiments combining increasingly intense lasers and energetic
particle beams will access new regimes of nonlinear, relativistic, quantum effects. This …

We review the progress in atomic structure theory with a focus on superheavy elements and
their predicted ground state configurations important for an element's placement in the …

The self-force expansion allows the study of deviations from geodesic motion due to the
emission of radiation and its consequent back-reaction. We investigate this scheme within …

Light–matter interactions driven by ultrahigh-intensity lasers have great potential to uncover
the physics associated with quantum electrodynamics (QED) processes occurring in neutron …

We discovered a simple regime where a near-critical plasma irradiated by a laser of
experimentally available intensity can self-organize to produce positrons and accelerate …

Waveforms are classical observables associated with any radiative physical process. Using
scattering amplitudes, these are usually computed in a weak-field regime to some finite …

The eXawatt Center for Extreme Light Studies project aimed to create a large scientific
infrastructure based on lasers with giant peak power. The project relies on the significant …

A bstract We generalise the Kosower-Maybee-O'Connell (KMOC) formalism relating
classical observables and scattering amplitudes to curved backgrounds. We show how to …

The investigation of spin and polarization effects in ultra-high intensity laser–plasma and
laser–beam interactions has become an emergent topic in high-field science recently. In this …

Accurate modeling is necessary to support precision experiments investigating strong-field
QED phenomena. This modeling is particularly challenging in the transition between the …
