Im not so familliar with particle physics and QFT and my logic gets muddy when I am transfering from classical field theory to particle interactions.
Suppose we have an antenna that is hit by an EM plane wave. The plane wave has an oscillating electrical field that excites the electrons in the antenna. The electrons inside the antenna start to oscillate up and down along the antenna according to the direction of the oscillating electric field. Simple enough.
On the otherhand, in particle physics, an EM plane wave consist of photons, as in energy quanta. The individual photons hit the electrons inside the antenna and transfer their energy thus exciting them, according to Compton scattering.
Here is when my logic gets muddy.
The electrons are supposed to oscillate up and down along the antenna according to the electrical field, but on the otherhand the individual photons, hitting the electrons, should move the electrons according to Compton scattering.
How does the photon energy transfer to the electrons determine the direction (along the antenna, up and down ) that the electrons move? How is it determined when a photon hits an electron inside the antenna does it move up or down?
