The recent development of novel light sources like x-ray free-electron lasers and table-top lasers for high-harmonic generation, which are capable of delivering controllable sequences of intense sub-femtosecond ionizing pulses, has opened the way to the monitoring and control of electron dynamics in atoms and molecules at its natural attosecond time scale. The coherent superpositions of highly excited states across a wide spectral range above the ionization threshold generated by the interaction of molecules with such pulses defeat the capabilities of most standard quantum-chemistry packages. In fact, the stationary state-based pictures familiar from lowest-order time-dependent perturbation theory may become altogether inapplicable. The purpose of this school, organized in cooperation with the XLIC COST ACTION CM1204, is to introduce its participants to state-of-the-art ab-initio, hybrid and TDDFT numerical methods that can cope with ultra-fast dynamics, with an emphasis on unbound states in strong-fields and on the need to go beyond single-active-electron models to properly account for the role of correlation. The course is directed to advanced master students, PhD students and young post-doctoral researchers in atomic and molecular physics, theoretical chemistry and applied mathematics, with an interest in developing new software for coherent control of electronic currents in systems with chemical interest.
