Computational Materials Science

is a very rapidly developing field of theoretical condensed matter physics. It started in the 50's and 60's by invention of sampling techniques such as Monte Carlo and Molecular Dynamics schemes. Another milestone was the formulation of Density Functional Theory and its combination with finite-temperature sampling in the form of ab initio molecular dynamics. Due to enormous progress in algorithms as well in computer hardware over the last decades it gained predictive power and has become invaluable tool in condensed matter physics. It is able to complement the experiment and in some cases even represents the only way to extract information about the properties of the system (e.g. in case of extreme conditions).

 

Current research directions

  • study of structural transformations in solids at high pressures
  • metadynamics-based simulations of structural phase transitions in crystals
  • structural prediction of crystalline and amorphous phases
  • development of new methods for computer simulations of condensed matter systems
  • study of quantum and thermal ripples in graphene

 

Former research directions

  • optimization by quantum annealing
  • polyamorphism of water
