Towards a Manifestly Causal Approach to Particle Scattering
Robert Dickinson, Jeff Forshaw, Ross Jenkinson +1
We introduce a new, probability-level approach to calculations in scalar field particle scattering. The approach involves the implicit summation over final states, which makes caus…

A new study of the Unruh effect
Robert Dickinson, Jeff Forshaw, Ross Jenkinson +1
We revisit the Unruh effect within a general framework based on direct, probability-level calculations. We rederive the transition rate of a uniformly accelerating Unruh-DeWitt mon…

Axion-Photon Mixing in 3D: Classical Equations and Geometric Optics
J. I. McDonald, P. Millington
Light particle-photon mixing in magnetised plasmas plays a vital role in constraining the existence of new physics, especially axions, dark photons, and ultra-high-frequency gravit…
