In the book "QED: The Strange Theory of Light and Matter" Feynman derives classical law of light reflection from mirror in a intuitive way from QED. but i want a more rigorous way from principles witch show details in context of QFT (or equivalently QED), for example why atoms of other matter and their arrangement don't behave so. and how mirror in quantum level is capable of such a interesting behavior.

QFT may seem magical, but it's not witchcraft. ; ) – PM 2Ring Apr 02 '18 at 20:54
