Towards an Autonomous Quantum Thermodyamic Machine — •Friedemann Tonner und Günter Mahler — Institut für Theoretische Physik 1, Universität Stuttgart, Pfaffenwaldring 57, D-70550 Stuttgart

On a fundamental level thermodynamic machines necessarily consist of quantum mechanical parts. Here we address quantum mechanical analogs to each functional part of a thermodynamic machine. Thus we construct time-independent Hamiltonians for the gas system, the work variable and the control system responsible for driving the thermodynamic process, normally controlled from the outside. Baths are dealt with in Markov approximation.

We are interested not in quantum mechanical modeling of existing (classical) machines, but rather in exploring the small system (quantum) limit: how small can a machine be made to still exhibit machine functions?
