CONTACT:Duncan Johnstone
DESCRIPTION:Recent experiments have revealed new forms and new dynamics of
  topological defects in mesoscopic and complex crystals\, such as flux-clo
 sure ferroelectric vortices in oxide superlattices\, magnetic skyrmions in
  thin-films\, dislocations and grain boundaries in graphene. At the same t
 ime\, the development of new multiple components materials\, such as high 
 entropy alloys\, challenges our traditional understanding of crystal defec
 ts and presents opportunities for the discovery of new physics. In this ta
 lk\, I will describe how the development of electron microscopy has contri
 buted the study of topological defects in mesoscopic and complex crystals.
  Two examples will be highlighted\, one is vortices in ferroelectric cryst
 als and the other is dislocation dynamics in high entropy alloys.
