Single-molecule electronics: Conductance mechanisms — •Gianaurelio Cuniberti — Institute for Theoretical Physics, University of Regensburg, D-93040 Regensburg, Germany

Since few years, several quantum transport experiments employing unimolecular systems have been proven. Some of related emerging phenomena, however, are still missing sound theoretical explanations. One principal limitation is the “static" description of molecular bridges typically assumed for transport processes. Molecules, indeed, are flexible objects and their nuclear “dynamics" plays in general a fundamental role in charge transfer as well as transport mechanisms. In this talk, I will give an overview on the role of vibrations and inelastic transport in molecular systems, and show how such phenomena do dramatically affect the overall conduction properties of molecular junctions.
