How exactly does Quantum Field Theory explain atomic structures? As I understand it oscillations in the quark fields are "held together" by other oscillations of the baryon matter field to form protons and neutrons (baryons, a type of hadrons), which are themselves held in a nucleus by oscillations of the strong force field? How are electron field oscillations held to the nuclei. Is it by the electro-magnetic force field, the weak force field, or the lepton matter field?
Follow up: Thank you very much for the answers, ladies/gentlemen. I realize that QFT isn't needed to explain atomic structure. It's just that I only recently became aware of QFT and I am absolutely fascinated by it. As a 29 year old electrical engineer I could never look the same way as I did until now at the field I've been working in my whole life. Please excuse me if my question isn't correctly formulated. Basically I want to know if my first statement about the nucleus is true according to QFT. And also what exactly holds the electrons "in orbit" around the nucleus. If it is the electromagnetic force then why electrons don't completely collide with the positively charged nucleus. Additionally as far as I know the weak force cannot produce bound states so what exactly is its role. If the weak force acts on the flavor of quarks and leptons and there is a separate field for each lepton and quark then what role if any plays the lepton matter field in holding an electron field oscillation (a lepton) in orbit around a nucleus. Are the separate lepton fields different entities from the lepton matter field??? I have Dr. Rodney Brooks' book 'Fields of Color' but I cannot find exact answers there. I also have professor Anthony Zee's book 'Quantum Field Theory in a Nutshell' and a few others, but I just don't have the possibility to spend as much time delving in these books as I'd like, so I'm hoping to get answers a little quicker in forums.
