Attosecond spectroscopy of optical-field-driven dynamics in solids

Prof. Dr. Lukas Gallmann | ETH Zürich

talks about

Attosecond transient absorption spectroscopy has evolved into a universal tool for studying bulk electron dynamics in solids driven by intense optical fields. We applied this technique to different material classes with a particular focus on the transient optical response on the shortest time scales. What is the relative importance of intra-band and inter-band electron dynamics or, in metals, of local screening effects versus electron gas heating?

I will review our recent work involving large-bandgap dielectrics, semiconductors and metals and provide an outlook on future directions in our related research activities.
