Crystallization and growth, and more generally structure formation, are ubiquitous in nature and technology. A quantitative understanding of these non-uilibrium processes, which can span several orders of magnitude of time and length scales, remains a challenge.
In this talk, we will first provide an overview of general concepts including classical nucleation theory and rate equation approaches to describe growth and illustrate these by simple examples of growth of elemental crystals.
We will then discuss to which extent these basic concepts can be generalized from elemental (atomic, single-component) systems to molecular systems and colloids, with their different interaction potentials and internal degrees of freedom.
This will lead us to the question of new growth phenomena in more complex materials and the need for more elaborate concepts to describe crystallization and growth, as we will demonstrate based on real-time experiments monitoring growth phenomena.
The lecture will try to connect input from theory, simulation, and experiment.
