A Manifestly Causal Approach to Quantum Field Theory
Ross Jenkinson
We develop a probability-level, manifestly causal formalism for calculations in QFT. The approach involves an implicit summation over final states, which makes causality manifest s…

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…
