Enhancing Ottomobile Efficiency via Addition of a Quantum Carnot Cycle Academic Article uri icon


  • It was shown recently that one can improve the efficiency of the Otto cycle by taking advantage of the internal degrees of freedom of an ideal gas [M. O. Scully, "The Quantum Afterburner", Phys. Rev. Lett., to be published]. Here we discuss the limiting improvement of the efficiency by considering reversible cycles with both internal and external degrees of freedom.
