Outline of Final Research Achievements

It is highly debated which of the competing approaches to the crystallization and glass transition is the most appropriate to describe the phase transition and relaxation of glass former. In this project, we numerically investigate nucleation from a liquid into the crystal by efficient event-based algorithms (i.e. event-chain Monte Carlo, and event-driven molecular dynamics) with up to one million hard sphere systems. We also investigate systematically the applicability of dynamic facilitation theory for glass-forming binary hard disk systems with event-based hybrid algorithms where supercompression is controlled by pressure rather than temperature.
