Quantum field theory unwelcomes the unphysical presence of self-interacting particles


Many have mused over the self-interaction of charged particles and the complexity this unphysical reality brings within quantum field theory. Dynamics governed by Maxwell-Dirac equations reveal that a charged particle interacts with its own field, leading to self-repulsion and enhancement of the spatial spreading of its wave packet. We demonstrate a framework that defines the individual fields of each particle. In such a case, particles are shown to couple to the electromagnetic field associated with the other particle (i.e. an electron couples to the field associated with a positron). With this knowledge, our research will turn towards negating self-repulsion while simultaneously maintaining the fully second-quantized framework within the realm of quantum field theory.
