By recourse to (i) the Hellmann–Feynman theorem and (ii) the virial one, the information-optimizing principle based on Fisher’s information measure uncovers a Legendre-transform structure associated with Schrödinger’s equation, in close analogy with the structure that lies behind the...

Using the kinetic description of a binary mixture of dissimilar hard spheres following a standard-like Enskog theory, we prove the reciprocity of the Onsager relations within the rigorous framework. This proof, added to previous results, places our description in complete agreement with linear...

The Onsager Symmetry Relations (OSR), which are of fundamental importance in Linear Irreversible Thermodynamics (LIT), are not obeyed by the linearized Burnett equations for a dilute gas. In this paper we present a solution to this problem, which consists of an enlargement of the space of...
