Abstract: | Caused by the interaction between the particles, structural fluctuations influence thermodynamics and order of transformation
of an ensemble of nanoparticles. A stringed thermodynamic analysis revealed that, in fluctuating ensembles, the ratio of particle
numbers in the equilibrium over the one in the non-equilibrium phase is independent of any metastable in between. Structural
transformations in such ensembles, connected to latent heat, are of infinite order. These findings are summarized in a set
of theorems ruling structural fluctuations. Finally, the consequences of fluctuations are demonstrated by an example. |
