Quasi-equilibrium nonadditivity
arXiv:1404.7601 · doi:10.1007/s10955-014-1177-6
Abstract
The possibility that a short-range interacting system exhibits nonadditivity is investigated. After the discussion on the precise definition of additivity and its consequence, we show that it is possible when the system is in a quasi-equilibrium state by examining the specific model, in which the spin degrees of freedom are coupled to the motional degrees of freedom and which exhibits a type of structural phase transitions.
