Research Activities/Specialties

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 both ab initio and 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 theoretical development and implementation of reliable semi-empirical models of inter-atomic interaction.
  • 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 development of potential energy landscape exploration algorithms for use in the study of structural and magnetic excitations.
