Quantum Equivalent of the Carnot Cycle

Physical Review, 1967
The concept of a quantum heat pump is proposed as a convenient model in the thermodynamic interpretation of certain multilevel processes. The ideal quantum heat engine is defined as an idealization of realistic pumped multilevel systems in much the same way that the well-known Carnot cycle is an idealization of physically realizable, classical ...

Optimization of the direct Carnot cycle

Applied Thermal Engineering, 2007
A model for the study and optimization of two heat reservoirs thermal machines is presented. The mathematical model basically consists of the First and Second Laws of Thermodynamics applied to the cycle and entire system, and the heat transfer equations at the source and sink.

Comments on the closure of the Carnot cycle

Journal of Chemical Education, 1985
Why did Carnot set up the cycle as he did, and didn't his first commentators adopt his procedure?

Carnot cycle for photon gas?

American Journal of Physics, 2001
The Carnot cycle for a photon gas provides a useful means to illustrate the thermodynamic laws. It is particularly useful in showing the path dependence of thermodynamic functions. Thermodynamic relationships to a neutrino gas are also drawn.

Equivalent Carnot cycles for sorption refrigeration

International Journal of Refrigeration, 1998
Abstract Temperature–entropy diagrams are usually used to describe heat-driven engines as well as vapour compressor refrigerators, but they have not yet been used for sorption refrigeration. Such Carnot cycles are introduced here to describe three sorption refrigeration technologies (liquid absorption, solid adsorption, chemical reaction).

The Carnot cycle and Maxwell's relations

Journal of Chemical Education, 1964
Maxwells equations can be derived from nothing more than the Carnot cycle and the deployment of the simplest plane geometry.
