1. Spatial and temporal aspects of intense attosecond pulses for pump-probe experiments
Abstract : Nuclear and electronic dynamics in atoms and molecules are the foundation of many physical processes and chemical reactions. Often, these dynamics take place on timescales so much shorter than those commonly encountered that they are called ultrafast. READ MORE

2. Photoemission Electron Microscopy for Ultrafast Nano-Optics - Femtoseconds to Attoseconds
Abstract : Ultrafast nano-optics is a new and quickly evolving research field centred around the control, manipulation, and application of light on a nanometre and femtosecond scale. This can lead to improved electro-optical devices, more sensitive spectroscopy, and real-time control of chemical reactions. READ MORE

3. Microcombs for ultrafast optical interferometry
Abstract : The optical frequency comb has revolutionized the field of laser spectroscopy. This type of laser, characterized by an array of uniformly spaced and coherent laser lines, finds promise in photonic platforms for the integration of chip-scale spectrometers. READ MORE

4. Investigation of Ultrafast Molecular Dynamics via Covariance Mapping : A Tool for Intense XUV Light Sources
Abstract : The study of molecular dynamics involves observations of the motion of nuclei and electrons. While nuclear motion is usually on the picosecond or femtosecond timescale, attosecond precision is necessary to directly observe the motion of electrons. READ MORE

5. Ultrafast Probing of CO Reactions on Metal Surfaces : Changes in the molecular orbitals during the catalysis process
Abstract : This thesis presents experimental studies of three different chemical reaction steps relevant for heterogeneous catalysis: dissociation, desorption, and oxidation. CO on single-crystal metal surfaces was chosen as the model systems. READ MORE
