The main scientific areas of the Laboratory are focused on computer modeling of structures and physical properties of functional materials. In research of substances on atomic and molecular levels, the methods of quantum-mechanical simulation based on density functional theory (DFT) and Hartree-Fock's method as well as the approaches involving empiric force fields are employed.
The Laboratory staff develops generation algorithms of configuration space in crystal structures for research of materials with disordered structure. The Laboratory members also perform research of correlated behavior of composition, structure and properties of advanced functional materials including intermetallides, solid electrolytes, electrode materials and MOFs.
Computer modeling of physical properties of crystal structures is conducted applying up-to-date specialized program packages including VASP, CRYSTAL, cp2k, QuantumEspresso, and DFTB+ for calculations in DFT. Calculations by the methods of classical molecular dynamics and empirical potentials study are implemented using LAMMPS, GULP, DL_POLY.
Computing resources of SCTMS enable performing quantum-mechanical ab initio calculations for unit cells consisted of hundreds of atoms, and calculations by the method of classical molecular dynamics for unit cells consisted of tens of thousands of atoms.
