Two topics are currently pursued in the team: Mesoscopic quantum physics and ab initio descriptions of electronic properties of materials. In the case of Mesoscopic quantum physics, the aim is to capture the physical mechanisms underlying a given phenomenon, providing qualitative and quantitative descriptions of experimental data. Firstly, a suitable model which is mathematically tractable and containing the essential ingredients is developed. Then, the model is solved by using analytical or numerical tools. The other axis aims at developing new computing methods giving a reliable description of the experimental results for the electronic structure and spin dependent transport of heterojunction materials devoted to spintronics technology. This study is undertaken by means of the spin-dependent density functional theory (DFT).
