Optical Creation and Control of Magnetic Spin Textures
(2025-07-04)Exploring the rich physics of magnetic spin textures, particularly topologically non-trivial magnetic skyrmions, opens a promising pathway for the development of novel spintronic and magnonic devices. This thesis investigates ... -
X-ray Imaging of Cavitation Dynamics with Free-Electron Laser Pulses
(2025-06-25)Cavitation dynamics are fast non-equilibrium hydrodynamic processes involving matter at extreme states. A first relevant mechanism is the light-matter interaction during (ultrafast) laser-induced optical breakdown and ... -
Connecting the Dots: Dust Particle Tracking at Comet 67P/Churyumov-Gerasimenko
(2025-05-21)Comets and their characteristic plasma and dust tails have been intriguing people for millennia. Early theories about their nature were for example already developed by the ancient Chinese and Greek, but it was not until ... -
Operando and Ultrafast Electron Microscopy of Structural Phase Transformations
(2025-05-05)Structural phase transformations promise tailored functionality in future technological devices that complement already established applications. In leveraging the associated changes of macroscopic properties, reversible, ... -
Stability and evolution of non-equilibrium states in the iron carbon system
(2025-03-20)The engineering of metastable microstructures has opened new avenues in advanced materials development. In Fe-C-based alloys, the drastic reduction in carbon solubility during the fcc-to-bcc transformation, in combination ... -
Sensory processing and learning in spiking neural networks
(2025-02-12)Organisms are capable of navigating an extremely complex environment with the help of their senses. To do this, they exploit that high dimensional sensory inputs can often be predicted from relatively sparse information, ... -
Stochastic (thermo)dynamics of molecular coupled processes
(2024-12-18)Out of equilibrium biological processes are the key for life. From large animals to the smallest proteins, life is sustained by a continuous throughput of free energy. This happens through the exchange of some form of ... -
Structure and Kinematics of the Broad-Line Region in Selected Changing-Look AGN
(2024-10-18)In this thesis, the results of three variability studies conducted on three individual active galactic nuclei (AGN) are presented. Each of these AGN belongs to the class of changing-look (CL) AGN, which are characterized ... -
Self-Organization of Filamentous Cyanobacteria
(2024-07-29)Cyanobacteria are phototrophic prokaryotes that occur in almost any natural habitat on Earth, from polar to tropical climates, from the Archaean to the present. Roughly 2.5 billion years ago, they have generated the ... -
