- Photo-Carnot_engine abstract "A Photo-Carnot engine is a Carnot cycle engine in which the working medium is a photon inside a cavity with perfectly reflecting walls. Radiation is the working fluid, and the piston is driven by radiation pressure.A quantum Carnot engine is one in which the atoms in the heat bath are given a small bit of quantum coherence. The phase of the atomic coherence provides a new control parameter.The deep physics behind the second law of thermodynamics is not violated; nevertheless, the quantum Carnot engine has certain features that are not possible in a classical engine.DerivationThe internal energy of the photo-Carnot engine is proportional to the volume (unlike the ideal-gas equivalent) as well as the 4th power of the temperature (see Stefan-Boltzmann law). The Radiation pressure is only proportional to this 4th power of temperature but no other variables, meaning that for this photo-Carnot engine an isotherm is equivalent to an isobar. Using the First law of thermodynamics we can determine the work done through an adiabatic expansion by using the chain rule and setting it equal to Combining these gives us which we can solve to find ....The efficiency of this reversible engine must be the Carnot efficiency, regardless of the mechanism and so".
