quantum electrodynamics
Quantum Electrodynamics (QED) is a branch of physics that describes the behavior of light and matter at the smallest scales, combining quantum mechanics with electromagnetism. It provides a theoretical framework to explain how electromagnetic interactions occur between charged particles by using mathematical equations and concepts such as virtual particles and quantum fluctuations.
