The mesoscopic foundations of non equilibrium thermodynamics and the arrow of time in the Dual Model of Liquids

Abstract

This manuscripts has two goals. The first goal is to show that the interaction in the Dual Model of Liquids between the solidlike molecule aggregates and the lattice excitations is appropriate to represent the link between the behaviour at macroscopic scale of normal liquids and the physical processes characterizing those systems at mesoscopic scale. The second goal is to show that the duality allows identifying a time arrow on the mesoscopic scale in liquids. The interaction of quanta of elastic energy with the molecular clusters introduces a privileged direction, which is relevant in time dependent and dissipative macroscopic processes, although the interaction remains temporally reversible
