Nucleation phenomena: The non-equilibrium kinetics of phase change Autors/ores David Reguera Department of Condensed Matter Physics, Faculty of Physics, University of Barcelona, Barcelona, Catalonia Paraules clau: phase transition, non-equilibrium, nucleation, metastable states, water Resum The molecules and atoms that comprise matter have the tendency to join in different aggregation states called phases. How these atoms and molecules manage to shift between these different states is one of the most fascinating processes in physics. These phase transitions are commonly controlled and triggered by a non-equilibrium physical mechanism, called nucleation, that describes the formation of the first seeds of the new phase. Nucleation is behind many phenomena of utmost scientific and technological interest, ranging from nuclear phenomena and biological assembly to galaxy formation. However, due to its rare non-equilibrium nature, it is still one of the few classical problems that remain incompletely understood. Indeed, deviations between theoretical predictions and experiments can reach several orders of magnitude. In this article, we review the essential aspects of nucleation and the challenges it poses to current research.
