Nanophotonics for pair production [PDF]
Nature Communications, 2023 The transformation of electromagnetic energy into matter represents a fascinating prediction of relativistic quantum electrodynamics that is paradigmatically exemplified by the creation of electron-positron pairs out of light.

Bulk Density Response and Experimental Study of Pulsed Neutron-Gamma Density Logging
Frontiers in Earth Science, 2022 The pulsed neutron-gamma density logging technique is used to measure the bulk density of formations based on the detection of gamma rays from the inelastic scattering of neutrons in the formations.

Lorentz Violation by the Preferred Frame Effects and Cosmic and Gamma Ray Propagation
Galaxies, 2021 The ‘relativity with a preferred frame’, designed to reconcile the relativity principle with the existence of the cosmological preferred frame, incorporates the preferred frame at the level of special relativity (SR) while retaining the fundamental ...

Laser-driven muon production for material inspection and imaging
Frontiers in Physics, 2023 We numerically show that laser-wakefield accelerated electron beams obtained using a PetaWatt-scale laser system can produce high-flux sources of relativistic muons that are suitable for radiographic applications.

A laser–plasma platform for photon–photon physics: the two photon Breit–Wheeler process
New Journal of Physics, 2021 We describe a laser–plasma platform for photon–photon collision experiments to measure fundamental quantum electrodynamic processes. As an example we describe using this platform to attempt to observe the linear Breit–Wheeler process.

Pair Production and Optical Lasers [PDF]
Physical Review Letters, 2006 Electron-positron pair creation in a standing wave is explored using a parameter-free quantum kinetic equation. Field strengths and frequencies corresponding to modern optical lasers induce a material polarisation of the QED vacuum, which may be characterised as a plasma of e^+ e^- quasiparticle pairs with a density of ~10^{20}cm^{-3}.
