"Strong-field-induced electron dynamics and attosecond phenomena in solids."

"In this talk, I will give an overview of our recent work on studying electron dynamics in dielectrics exposed to few-cycle laser pulses with a peak intensity just below the damage threshold. Until recently, detailed time-resolved measurements of electron dynamics in this extreme regime of light-matter interaction used to be out of reach. The situation has recently changed due to the progress in the generation of few-cycle laser pulses and the related progress in attosecond physics. After a brief presentation of recent experiments performed in the Laboratory for Attosecond Physics (MPQ, Garching), I will report on our related theoretical work, where we studied the dynamics of interband excitations and the light-driven motion of charge carriers under conditions where the conventional nonlinear optics breaks down, and the Bragg-like scattering of electrons at edges of the Brillouin zone (Bloch oscillations) starts to play an important role."
