“…In the century since its first formulation by Lorentz and Abraham [1,2], there have been many theoretical investigations, but so far laboratory-based electromagnetic fields have not been sufficiently intense to produce an appreciable RR effect. A number of astrophysical scenarios do exist for which RR is important [3][4][5], but the impossibility of controlling the conditions of these events means a clear signature of RR has yet to be detected. A new generation of laser facilities, such as the Extreme Light Infrastructure (ELI), are anticipated to produce field intensities on the order of 10 23 W/cm 2 , where RR will not just be significant but will dominate the electron dynamics [6].…”

It has been developed to disseminate open access research outputs, expose data about those outputs, and enable the management and persistent access to Strathclyde's intellectual output. Radiation reaction remains one of the most fascinating open questions in electrodynamics. The development of multi-petawatt laser facilities capable of reaching extreme intensities has leant this topic a new urgency, and it is now more important than ever to properly understand it. Two models of radiation reaction, due to Landau and Lifshitz and to Sokolov, have gained prominence, but there has been little work exploring the relation between the two. We show that in the Sokolov theory electromagnetic fields induce a Lorentz transformation between momentum and velocity, which eliminates some of the counterintuitive results of Landau-Lifshitz. In particular, the Lorentz boost in a constant electric field causes the particle to lose electrostatic potential energy more rapidly than it otherwise would, explaining the long-standing mystery of how an electron can radiate while experience no radiation reaction force. These ideas are illustrated in examples of relevance to astrophysics and laser-particle interactions, where radiation reaction effects are particularly prominent.
