FWF Erwin Schrödinger Fellowship
Driving and controlling nanoscale electron correlations
FWF Erwin Schrödinger Fellowship — Project No. J3890
Host institution: SISSA — Trieste (Italy)
Funding period: 10/2016 - 07/2018
Individual fellowship funded by FWF for young scientists. Link to FWF page [link].
Aim of the Project
The aim of the project is two-fold: (i) the understanding of electron-electron correlations stemming from the Coulomb interaction in low dimensions; (ii) the search for new routes to manipulate the electronic, magnetic, and transport properties of materials, relevant for technological application. Both aspects stand at the forefront of research in modern theoretical condensed matter physics. From the methodological point of view, the physical applications to systems of interests are carried out within the unified many-body framework of dynamical mean-field theory (DMFT) and its extensions, which are able to provide a quantitative description of the electronic structure and the transport properties of nanostructured materials.
