If I had 2 charged slabs that were moving together at relativistic speeds would both slabs
emit cherenkov radiation. In each of the rest frames of the slabs the other slab is approaching it at a speed that is faster than the group velocity of light in in its material.
Is the spin of a photon just polarization.
To create entangled photons do I just need to excite an atom so it will emit 2 photons at the same time.
If I Electrically polarize a material does it affect the Raman shift.
