DESCRIPTION:Prof. Dr Angel Rubio\nMax Planck Institute for the Structure a

  and ETSF Scientific Development Centre\, Universidad del País Vasco\, UP

 ny\nIn this talk we will review the recent advances within density-functio
 nal and many-body based schemes to describe spectroscopic properties of co
 mplex systems with special emphasis to modelling  time and spatially reso
 lved electron spectroscopies (including transient pump-probe techniques).
    Pros and cons of present functionals will be highlighted and provide 
 insight in how to overcome those limitations by merging concepts from many
 -body perturbation theory and time-dependent density functional theory.  
 We will discuss some of the theoretical approaches developed in the group 
 (and under development)  for  the characterisation of matter out of equi
 librium\, the control material processes at the electronic level and tailo
 r material properties\, and  master energy and information on the nanosca
 le to propose new devices with capabilities. We will focus on examples  l
 inked to the efficient conversion of light into electricity or chemical fu
 els ("artificial photosynthesis") and the design on new nanostructured bas
 ed optoelectronic devices based on inorganic nanotubes\, among others.  T
 he goal of the group activities in the long-run 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 dissipa
 tion in quantum many-body systems. With  the help of quantum optimal cont
 rol (QOC) theory and the mastery over spectroscopy we could  direct the m
 ovement of electrons\, selectively trigger chemical reactions and processe
 s\, and create new materials.
