Description
Abstract
Attosecond transient absorption spectroscopy (ATAS) serves as a paramount technique for tracking real-time electronic motion and coherence in matter with unprecedented temporal resolution. Extending this technique towards higher photon energies adds an element sensitive probe as it allows to access core electrons. Apply to many body physics it allows to resolve both electron and lattice dynamics and therefore bringing new insights on the interaction among them.
In this work we present an overview of the recent developments in the field including our latest result on solid samples and also an overview on the generation and characterization of pulses down to 19 attoseconds.
