    Thermodynamic laws in isolated systems by Hilbert, Stefan, Hanggi, Peter, Dunkel, Joern

    Published 2014
    “…Here we provide a detailed comparison of the most commonly considered microcanonical entropy definitions, focusing specifically on whether they satisfy or violate the zeroth, first, and second laws of thermodynamics. Our analysis shows that, for a broad class of systems that includes all standard classical Hamiltonian systems, only the Gibbs volume entropy fulfills all three laws simultaneously. …”
