Abstract:This paper generalizes isomorph theory to systems that are not in thermal equilibrium. The systems are assumed to be R-simple, i.e., have a potential energy that as a function of all particle coordinates R obeys the hidden-scale-invariance condition U (Ra) < U (R b ) ⇒ U (λRa) < U (λR b ). Generalized "systemic" isomorphs are lines of constant excess entropy in the phase diagram defined by density and systemic temperature, which is the temperature of the equilibrium state point with average potential energy eq… Show more
