So according to classical electrodynamics, an electron would produce an electric field that is a physical entity in and of itself. This field has momentum so when a test charge is placed within this vicinity, it would be affected by the field itself, not the electron. But what about the QFT way of looking at it? I've heard that charge is created when the electron field and the electro magnetic field oscillate due to inputing energy. And that this charge happens at a contour of the energy function where the strength of the em field and the electron field are the inputs of the energy function. So the electron particle is an excitation of the electron field, but what about the excitation of the electromagnetic field? Where does that manifest itself? Is it the static electric field that we always see? But then wouldn't that static "field" then be made of particles since it too is an excitation? So would the static electric "field" of the electron not be the lowest state of fundamental field itself but an excitation of it? So then it isn't a continuous field per se like the classical image of it.
