Peter Derlet is a senior staff scientist within the Condensed Matter Theory group at the Paul Scherrer Institut, Switzerland. He specializes in the atomistic modeling of materials science related issues using semi-empirical methods. His fields of interest are:
  • The mechanical properties of materials with complex defect structures.
  • The dynamical properties of local and extended defects.
  • The development of simulation tools to model the experimental measurement of structural disorder using neutrons, photons and electrons.
  • Classical magnetization dynamics in micro- and meso-scopic magnetic systems.
  • The vibrational and configurational dynamics of structural glasses well below the glass transition temperature.
  • Avalanche statistics using simplified dislocation dynamics geometries.
  • The use of potential energy landscape exploration algorithms for use in the study of structural and magnetic excitations.
