Computational Methods

First principle (ab initio) methods provide significant insight about the electronic structure (ES) and physical properties of structures of interest in physics, chemistry, biology and materials science. For example, these methods are useful for understanding the electronic structure of active sites in metalloproteins and for interpreting experiments that probe their ground or excited states. In particular, spin Kohn-Sham density functional theory (KS-SDFT) is a powerful method for studies of electronic structure of large transition metal-containing complexes. Spin density functional theory takes into account electronic exchange and correlation effects which are important for the description of spin-polarized open-shell transition metal clusters.  Density functional theory in conjunction with high performance supercomputers is a powerful tool for studies of electronic structure and molecular magnetism.

Our group has developed a number of post-SDFT methodologies for the accurate prediction of a number of physico-chemical properties of transition metal-containing systems. One main output of our development has been the inclusion of spin-orbit couplig (SOC), which is a relativistic effect, on top of conventional non-relativistic Khon-Sham calculations.
