My understanding of the QFT model of a free electron is that there is a localized higher energy level in the electron matter field which couples to the EM field in two ways: (1) the coupling allows the electron matter field to 'feel' a force from an outside EM field and accelerate in response and (2) the electron matter field excitation generates a localized higher energy level in the surrounding EM field which can be interpreted as an 'attached' EM field (really just a local higher energy level in the single EM field pervading all space-time). Does this characterization sound correct? If so, why doesn't the locally generated EM field loop back to self-interact with the associated electron matter field?
