Intro to Quantum Mechanics II
Quantum electrodynamics (QED) is the relativistic quantum field theory that describes how light and matter interact, focusing on the exchange of photons between charged particles. This theory combines the principles of quantum mechanics with special relativity, resulting in a framework that provides insight into phenomena such as electron-photon interactions and the structure of atoms. QED plays a crucial role in understanding selection rules and transition probabilities, as well as in the quantization of the electromagnetic field.
