Entropy: Classical and Quantum
Marlan O. Scully
The entropy concept is both a useful engineering tool and a philosopher’s lodestone. Indeed Planck was led to the quantum of action by studying the entropy of thermal light and Einstein was led to the photon concept following Planck’s studies. A century later we are still fascinated by (quantum) thermodynamics; For example, the quantum heat engine [1] and the entropy of laser light [2,3] will be discussed.
