WebAug 29, 2014 · Although it has not been proved yet, I think it is possible to prove convergence to classical dynamics for a (simple) model of QED, describing rigid charges interacting with the quantized EM field. The Hilbert space is H = L2(R3) ⊗ Γs(C2 ⊗ L2(R3)) ( Γs is the symmetric Fock space).

Taking the example of the force between two electrons, the classical theory of electromagnetism would describe it as arising from the electric field produced by each electron at the position of the other. family dinner on hbo
