• electronic structure calculations of solids from fundamental equations of quantum mechanics (from first principles, or ab initio)
  • investigations of connections between structure and properties of technologically important materials
  • calculation of theoretical strength of materials, modelling their behavior at extreme mechanical loading
  • studies of the influence of extended defects (grain boundaries, antiphase and interphase boundaries) and of surface phenomena on mechanical and magnetic properties of materials
