As the title says.
I'm currently learning about the normal Zeeman Effect and it seems as if different polarizations of the light that falls on an electron affects (slightly) the Energy state where this electron ends up. My question would be where this extra energy comes from. Maybe it could come from the wavelength difference between types of polarized light...
Currently self-studying Electrodynamics by Griffiths with the goal of reaching basic quantum field theory someday. Is it sufficient to stop studying electrodynamics after finishing Griffiths or does one need content from Jackson until a certain chapter?
if this effect is possible then i deserve a noble prize for the first real warp drive design XD
I've come across explanations for how charge screening occurs in QED from different reading materials, be it websites or online open lecture notes from universities, the explanation is usually: An electron is surrounded by a cloud of virtual electron-positron pairs, since virtual positrons are positively charged, they're closer to the electron and thus screens the electron charge.
Usually this charge screening explanation is coupled with an explanation for anti-screening in quantum chromodynamics, which is: In QCD vacuum, there exists a cloud of virtual quark-antiquark pairs which would give rise to a charge screening similar to the one in QED, however, due to the self-interaction of gluons, the vacuum will also be filled with a cloud of virtual gluons which carries colour charge, as a result, the colour charge increases with larger distances.
Since virtual particles are just mathematical tools arising from perturbation theory and don't represent real particles, these explanations for charge screening involving virtual particles can't be correct. What's really going on in these screening processes?
This semester I have to take both classes (along with a lab to go with Electrodynamics), and I have a few days before they start. Is there anything in particular I should brush up on or study before starting out?

I just finis my last course about quantum mechanics and now T would like to know about quantum electrodynamics its application like in matter of chemistry or biology, Some good recommendation about it?
Thanks
