Pixel Detector Studies for the ATLAS ITk Upgrade for the HL-LHC
(2023-06-02)The integrated luminosity of the Large Hadron Collider (lhc), which is proportional to the number of particles colliding and thus data being collected, is planned to be increased by a factor of 5-7.5 compared to the ... -
Orbital-order phase transition and non-adiabatic quantum-classical dynamics in strongly coupled electron-phonon systems
(2023-06-01)This thesis contributes to the investigation of solid-state systems with a strong coupling between electrons and the surrounding atomic lattice (phonons). One focus point of the thesis is the material class of $Pr_{1-x}C ... -
Novel Approaches to the Fast Simulation of the ATLAS Calorimeter and Performance Studies of Track-Assisted Reclustered Jets for Searches for Resonant $X \rightarrow SH \rightarrow b\bar{b} WW^*$ Production with the ATLAS Detector
(2023-05-30)One of the most essential tools for all measurements and searches at the LHC experiments is the Monte Carlo (MC) simulation of proton-proton collisions. The generation of MC events, in particular the simulation of the ... -
Interactions Within and Between Cytoskeletal Filaments
(2023-05-26)Cellular mechanics are determined by the cytoskeleton which consists of three different kind of biopolymers – actin filaments, microtubules and intermediate filaments – which form an intricate network. Each filament type ... -
Tripartite Information and Scrambling in Quantum Many-Body Systems
(2023-05-11)This thesis contributes to the study of quantum chaos and thermalization of closed quantum systems by applying tools from quantum information theory. We study scrambling – the delocalization of quantum information – in ... -
UV laser modification of transparent materials for photonic applications
(2023-04-28)Photonic applications have experienced strong growth in recent years. Due to increasing digitalization and automation in all areas of life, further growth of photonics is expected in the future. The broad range of photonic ... -
Empirische Studien zur horizontalen Vernetzung in naturwissenschaftlichen Schulbüchern und zur Förderung situationalen Interesses im fächerübergreifenden Unterricht
(2023-04-28)The implementation of integrated science education has already been a widely discussed topic in Germany for several decades. The arguments put forward are, on the one hand, a learning-promoting linking of subject content ... -
Towards an active matter perspective on sarcomere dynamics in cardiomyocytes
(2023-04-19)The contraction of cardiac muscles emerges from the collective dynamics of myosin motor proteins organized in sarcomeres, 2 μm-sized contractile units. Inside individual cardiomyocytes, dozens of sarcomeres in series form ... -
Cloud Microphysics Investigations with the Cloudkite Laboratory
(2023-04-14)Clouds are crucial to the Earth’s radiation budget and energy balance. Inadequately resolved cloud processes are a major source of uncertainty in weather forecasts and climate prediction. Due to their turbulent nature, ... -
Small-scale dynamo in cool main-sequence stars
(2023-04-13)Cool stars have an outer convection zone which can produce magnetic fields. These fields have a large scale component that is dependent on the solar cycle, as well as small-scale component largely independent of the cycle. ... -
Exoplanet Atmosphere Characterization with High-Resolution Doppler Spectroscopy
(2023-03-24)Ultra-hot Jupiters (UHJs) are a class of giant strongly irradiated exoplanets with dayside temperatures exceeding 2200 K. Due to their elevated temperatures, these objects are prime targets for atmospheric characterization ... -
Microscopic foundation of the Eigenstate Thermalization Hypothesis
(2023-03-20)The Eigenstate Thermalization Hypothesis (ETH) explains how isolated quantum many-body systems thermalize by proposing that each energy eigenstate is already thermal. The hypothesis is believed to be essential to the ... -
Actin structure formation, membrane dynamics, and force generation during blood platelet spreading
(2023-03-17)Blood platelets are essential to the formation of blood clots and prevent uncontrolled bleeding. They are non-nucleated fragments of larger bone marrow cells known as megakaryocytes. Platelets undergo fast morphological ... -
A coronal loop in a box: From energy generation to coronal emission
(2023-03-17)The corona is the outer atmosphere of the Sun. It contains an abundance of bright arcs that consist of hot plasma trapped by the magnetic field. These coronal loops are heated to temperatures far surpassing the solar surface ... -
Investigation of laser-induced structures on metal surfaces produced via two-beam and laser-plasmon interference
(2023-03-15)Periodic surface structures can change the properties of material surfaces. The obtained various functionalities strongly depend on the type of the specific structures. This work deals with the generation of periodic ... -
