Novel Analyses of Dynamics and Thermodynamics of Finite Systems

A discussion and reexamination of the fundamental notions and concepts of dynamics and thermodynamics, such as temperature, entropy, specific heat, degrees of freedom, and equipartition theorem, as applied to finite systems will be presented [1]. These notions and concepts will be reformulated in a way that explicitly displays the dependence on the system size. A new equipartition theorem will be formulated and the notion of dynamical degrees of freedom (distinct from the traditional, kinematical degrees of freedom) will be introduced. Illustrations of the use of the dynamical degrees of freedom as a powerful tool of dynamical analysis will be given.
