Beschreibung

In this talk we will review the recent advances within density-functional and many-body based schemes to describe spectroscopic properties of complex systems with special emphasis to modelling  time and spatially resolved electron spectroscopies   We will discuss the theoretical approaches developed in the group  for  the characterisation of matter out of equilibrium, the control material processes at the electronic level and tailor material properties, and  master energy and information on the nanoscale to propose new devices with capabilities. We will focus on examples  linked to the efficient conversion of light into electricity or chemical fuels ("artificial photosynthesis") and the design on new nanostructured based optoelectronic devices based on inorganic nanotubes, among others.  The goal is to provide a detailed, efficient, and at the same time accurate microscopic approach for the ab-initio description and control of the dynamics of decoherence and dissipation in quantum many-body systems. With  the help of quantum optimal control (QOC) theory and the mastery over spectroscopy we could  direct the movement of electrons, selectively trigger chemical reactions and processes, and create new materials
