Theoretical quantum-mechanical and quantum-chemical study of electronic structure of solid surfaces, clusters and other nanostructures (mainly transition metals).
Chemisorption of atoms and simple molecules on these systems. Both magnetic and non-magnetic systems are studied.
Use of first-principles and semi-empirical (for complex non-periodic structures and/or for systems with important spin-orbit coupling) computational codes.
Catalysis, magnetic recording media, material science.
Interpretation of experimental results (e.g. photoemission spectra). Understanding trends in surface reactivity from energy calculation and from analysis of the local electronic density of states. Understanding and prediction of magnetic properties at nanoscale (value of magnetic moments, magnetic anisotropy, character of magnetic coupling, and sensitivity of these quantities to effects such as geometry changes or chemisorption).
