- Chairman: Prof. Luis Roso (Centro de Láseres Pulsados)
The conversion of light to fundamental excitations of matter is governed by the build-up of electronic coherences and their dephasing to excited quasiparticles due to scattering processes, which occur on atto- and femtosecond timescales. Disentangling the interplay of these mechanisms, and how they lead to a specific flow of energy inside a material, is extremely challenging since many of...
Few cycle optical fields at allow manipulating electronic and spin degrees of freedom in solid state systems at optical clock rates faster than de-coherence. As an example I will discuss ultrafast bidirectional energy transfer between a light-field and the band-structure of silica and optically induced spin transfer in ferromagnetic heterostructures.

The quest of achieving complete control over the generation of coherent x-ray sources has driven the efforts over the scientific community during the last years due to their unique ability to capture the fastest electronic and spin dynamics in a wide variety of materials. Among other x-ray sources, high-harmonic generation (HHG) stands as a robust mechanism to generate highly spatially and...
X-ray photon correlation spectroscopy (XPCS) enables the study of sample dynamics between micrometer and atomic length scales. As a coherent scattering technique, it significantly benefits from the increased brilliance of the next-generation synchrotron radiation and Free-Electron Laser (FEL) sources.
In my presentation I will introduce the XPCS concepts and show some recent examples of...
