WebNov 1, 2024 · 1 Answer. You can't have the hydrogen atom as a state in QED with protons and electrons, because it is a bound state and hence it is nonperturbative. QED is inherently a perturbative theory. There are good reasons to believe that QED doesn't even exist nonperturbatively, unless it is associated with a broken phase of a non-abelian gauge … evidence based programs for juvenile justiceWebApr 12, 2024 · Part of the ATLAS experiment at CERN’s Large Hadron Collider.
