First-Principle Derivation of Single-Photon Entropy and Maxwell–Jüttner Velocity Distribution
This work is devoted to deriving the entropy of a single photon in a beam of light from first principles. Based on the quantum processes of light–matter interaction, we find that, if the light is not in equilibrium, there are two different ways, depending on whether the photon is being added or bein...
