"QUANTUM THERMODYNAMICS AND CONTROVERSY: Problems Physical and Psychological"

Marlan O. Scully
Texas A&M, Princeton, and Baylor Universities


Studying the entropy of thermal light led Planck to the quantum of action and Einstein to the photon. It also led to criticism. Fifty years later Einstein's stimulated emission concept resulted in the maser which is a quantum heat engine. During the development of the maser, Rabi and Kush told Townes to stop this silly project. Still later, lasing without inversion led to a new kind of quantum heat engine which could produce work from one thermal bath via quantum coherence. This was and is the subject of substantial controversy. More recently, electromagnetically induced transparency based quantum thermodynamics has been studied by Harris. This has stimulated investigation and disagreement concerning the entropy of laser light and the entropy of the BEC ground state. Several such quantum concepts and related argumentation will be presented.
