Description
We discuss the concept of an upper limit to the electromagnetic force and its effect on charged particle dynamics. We explore two examples: the Born-Infeld (BI) theory of electromagnetism providing a limiting field – and the limiting acceleration inherent to the
Eliezer-Ford-O’Connell (EFO) formulation of the radiation reaction force. We also explore the Euler-Heisenberg-Schwinger effective action of QED. The BI limiting field strength leads to a finite charged particle energy density as well as a modification of particle dynamics in strong fields: We show the effects of the BI limiting field in relativistic heavy ion collisions. We then describe how limiting acceleration emerges from the EFO radiation reaction force and evaluate charged particle dynamics. Finally, we explore similarities between the BI and EFO formalism and search for possible connections between the two.
