Primordial Magnetic Fields: Evolution and Signatures
(2024-05-21)Magnetic fields permeate our Universe on all cosmic scales: from planets and stars to the large-scale fields found in galaxies and galaxy clusters. Different observational methods, such as the ones using the Faraday rotation ... -
Global scale magnetic field extrapolation in the solar corona using a Yin Yang grid
(2024-05-06)The solar magnetic field significantly influences and structures the solar coronal plasma as magnetic forces are the dominant forces within the solar corona. Therefore, an in-depth understanding of the phenomena that occur ... -
Eigenstate overlaps in the Transverse Field Ising Model and the Axial Next Nearest Neighbour Model
(2024-05-03)In this thesis, a possible extension of the adiabatic theorem for quantum quenches, i.e. non-adiabatic changes, is checked for its validity. In particular, the Transverse Field Ising Model (TFIM) and the related Axial Next ... -
Anti-aging and avalanche dynamics in ultrastable metallic glasses by X-ray photon correlation spectroscopy
(2024-04-23)Within this thesis, structural relaxation dynamics of vapour deposited as well as conventionally produced metallic glasses are studied. Vapour deposition enables to crucially tune the surface diffusion during the deposition ... -
Vektorfeldkonzepte in der Studieneingangsphase Physik
(2024-04-16)The visualization of vector fields as vector field diagrams finds its application in various physics areas and also provides a valuable learning opportunity for physics students. By visualizing concepts and properties of ... -
Coupled dynamics of the spread of COVID-19, interventions and human behaviour
(2024-03-14)The COVID-19 pandemic has presented an unprecedented challenge to global health, prompting a need for comprehensive research into the coupled dynamics of virus spread, intervention strategies, and human behavior. This ... -
Sustainable mobility with bi-modal public transport
(2024-02-27)The escalating problems of pollution, traffic congestion, resource consumption, and environmental degradation are becoming increasingly significant due to the growing demand for urban mobility. This mounting crisis is ... -
Magneto-thermal conductivity of perovskite manganite films and exchange-spring coupled superlattices
(2024-02-21)In this thesis, thin colossal magnetoresistive perovskite manganite films and superlattices forming an exchange spring magnet were studied regarding their magneto-thermal conductivity. Using the metalorganic aerosol ... -
Legacy cross-section measurements of the $t\bar{t}Z$ production process in the trileptonic final state at $\sqrt{s}=13\,$TeV with the ATLAS detector
(2024-01-31)After three years of data-taking during the second run of the LHC at CERN, Geneva, Switzerland, the ATLAS detector has recorded its most extensive proton-proton collision data set to date, allowing for a wide range of ... -
Non-Equilibrium Dynamics of Photoexcited Correlated Quantum Matter
(2024-01-22)The interaction of time-dependent electromagnetic fields with electrons in quantum materials can give rise to many both fundamentally interesting as well as technologically relevant phenomena like transient band structure ... -
Data Analysis of Musical Timeseries
(2024-01-08)Music, despite its ubiquitous familiarity, is surprisingly hard to define. Should one consider its acoustic features, the mechanics by which it is produced and performed, as well as the cultural norms attached to them, ... -
Ultrafast momentum microscopy of dark exciton dynamics in real- and reciprocal-space
(2023-12-22)Combining both worlds of momentum and real-space time-resolved momentum microscopy, this thesis introduces a new approach to probe the entire exciton landscape and dynamics of twisted TMD heterostructures with momentum-, ... -
Numerical Modelling of Zonal Winds on Gas Giants
(2023-12-22)The outer regions of both Jupiter and Saturn host strong, alternately eastward and westward zonal winds. These are essentially steady in time and cover all latitudes, albeit diminished in amplitude at the mid-to-high ... -
Spreading Processes in Complex Networks of Cultured Neurons and Society
(2023-12-22)Complex networks appear across various contexts of our lives. Telecommunication, transport, infrastructure and finance are candidates to come to mind, and we humans ourselves, just going about our day as usual, meeting ... -
Unraveling Femtosecond Spin and Charge Dynamics with EUV T-MOKE Spectroscopy
(2023-12-15)In this thesis, a novel transverse magneto-optical Kerr effect (T-MOKE) setup with extreme ultraviolet light from high-harmonic generation between 30 and 72 eV is used to study the spectrally-resolved spin and charge ... -
Biomolecular space exploration - Phase space and parameter space sampling in realistic protein-lipid environments
(2023-12-11)Lipid composition affects membrane properties and specifically adapted compositions allow biomembranes to fulfill their functions. By altering membrane properties lipids regulate biological processes. Specifically, membrane ... -
Non-equilibrium Phases in Jahn-Teller-distorted Perovskite Manganites
(2023-12-04)Optical control of condensed matter, being inherently fast and energy efficient, sparks hope for potential technical applications. However, these require a fundamental understanding of the physical mechanisms behind. In ... -
