Abstract, Event Details: 

High harmonic generation provides a unique technique to generate coherent light up to keV photon energies, which is emitted in pulses a few tens of attoseconds in duration. Such pulses can now be used to probe dynamics in matter on the time scale of electronic motion. I will present our theoretical efforts to perform numerical calculations capturing the highly nonlinear process of attosecond pulse generation on both the microscopic level of a single atom and the macroscopic level of the generating gas medium consisting of billions of atoms. In the second part I will then discuss examples of the application of attosecond pulses to resolve electron dynamics in atoms and molecules.
