RESEARCH INTEREST:

I use computer simulation of nano-materials to find the new materials for technological and biomedical applications. In my research, I apply Density Functional Theory (DFT) and Dynamical Mean-Field Theory (DMFT) approaches to study the electronic and magnetic properties of transition metal nanosystems of different sizes and compositions. In particular, in order to take into account dynamical electron correlation effects (time-resolved local charge interactions), we have adopted the DFT+DMFT formalism and made it suitable for application to nanostructures. We have developed our own nano-DFT+DMFT code and applied it to examine the magnetization of iron nano-particles containing 10-147 atoms.  We have also developed DFT+DMFT code which is suitable to study systems with mixed geometry which are periodic (infinitely extended), in two directions, and finite in the third. Up on application of this code on Fe2O3 film we found remarkable improvement of results as compared to data available in DFT and DFT+U approach. In parallel, we have carried out a systematic study of magnetic anisotropy in bimetallic L10 FePt nanoparticles (20-484 atoms) by using two DFT-based approaches: direct and the torque method. We find that the magneto crystalline anisotropy (MCA) of FePt clusters is larger than that of the pure Fe and Pt ones. We find that particles whose (large) central layer consists of Pt atoms, rather than Fe, have larger MCA due to stronger hybridization effects. Such ‘protected’ MCA, which does not require protective cladding, can be used in modern magnetic technologies such as magnetic hard disk for computer uses and in cancer treatment by hyperthermia technique. All these work require lots of code development and computational uses. We are using super computers for this purpose.

Currently I am supervising six research students. The students are working on their M.S. thesis.

I am also working in collaboration with Professor Talat Rahman, at University of Central Florida, USA.
