DESCRIPTION:Speaker: Christoph Dellago\nhosted by Bingqing Cheng\nAbstract:
  Exploring the mechanism and kinetics of nucleation processes with compute
 r simulations: from crystallization to cavitationChristoph DellagoFaculty 
 of PhysicsUniversity of ViennaVienna\, AustriaComputer simulations of firs
 t order phase transitions occurring via nucleation and growth are demandin
 g for several distinct but related reasons. Particularly close to coexiste
 nce\, the free energy barrier separating the metastable from the stable ph
 ase can be high\, leading to nucleation times that vastly exceed the time 
 scales accessible to molecular dynamics simulations. Other difficulties ar
 ising in the simulation of nucleation processes consist in detecting local
  structures characteristic for the stable and metastable phases and in ide
 ntifying the degrees of freedom that capture the essential physics of the 
 transition mechanism. In this talk\, I will discuss simulation approaches 
 to address these problems\, using crystallization\, bulk melting and cavit
 ation as illustrative examples.
