Abstract

This paper focuses on the basic system of a field and a particle in interaction and provides a single, unified derivation of the energy-momentum tensors for both the field and the particle. This derivation contrasts with the usual approach in text books, where these two tensors are derived separately via different considerations. The unified treatment thereby provides an immediate description of overall energy and momentum conservation for such a system.
