This page shows details on the project. The primary projects are displayed together with a list of sub-projects.

Project description:The aim of the project NeTENaF is a thorough study of electronic transport through nanojunctions characterised not only with electronic but also vibrational degrees of freedom. Vibrations and their interactions with electrons lead to many qualitatively novel features in the character of quantum transport, e.g. the decoherence of one-electron states, local non-equilibrium heating in nanostructures, or opening of new inelastic channels for transport. Within the project NeTENaF we will describe electrons using the so called stroboscopic bases that represent particularly effective and clever tool for addressing non-equilibrium problems in quantum transport. The use of this basis transforms the problem of an open and interacting systems of electrons and phonons into a numerically solvable task. We will particularly focus on theinelastic transport in metallic and semiconducting carbon nanotubes with local defects created with either an ad-atom or a molecule adsorbed in the outer or inner side of the nanotube.
