 Overview

 

The dynamics of complex systems is often driven by rare but important events.  Well-known examples include conformational changes of bio-molecules, chemical reactions, nucleation events during phase transitions, etc.  Typically a small amount of noise is present in the system, and it is this that drives these rare events.  The long time scale associated with these rare events is a consequence of the disparity between the effective thermal energy and typical energy barrier of the system.  The dynamics proceeds by long waiting periods around metastable states followed by sudden jumps from one state to another.


Sophisticated theory and numerical techniques have been developed to find the transition pathways and transition rates between metastable states in complex systems for which the mechanism of transition is not known beforehand.  The aim of this workshop is to bring together researchers working on rare events and related problems, as well as young researchers interested in this area, to foster learning, exchange of ideas  and collaboration, and to promote further progress in our understanding of the subject matter.


Topics to be covered in the workshop include, but not restricted to: mathematical theory for modeling rare events, numerical methods for computing transition paths and transition rates, saddle point search, and applications to applied sciences.
