Multiscale Materials Modelling Group

The Multiscale Materials Modelling (MMM) group focuses on the development and application of simulation methods based on density functional theory (DFT) and empirical potentials (force fields). The main tool developed and employed by the group for its modelling activities is the CP2K program package. The MMM group is also member of the CP2K foundation.

Focus areas are currently the modelling of

  • strongly correlated materials based on DFT augmented with a Hubbard U term (DFT+U)
  • mechanical behaviour of fluorite-type oxide materials using DFT and force fields
  • XAFS spectra based on ab initio molecular dynamics (AIMD) simulations using the MD-EXAFS approach
  • chemical processes including rare events using accelerated molecular dynamics (AMD) methods especially metadynamics
