An FPGA-based Sampling ADC for the Crystal Barrel Calorimeter
(2019-12-09)
The CBELSA/TAPS experiment in Bonn investigates the excitation spectra of protons and neutrons through meson-photoproduction. With its ability to polarize the target nucleons and the incident photon beam, the experiment ...
Investigation of Paraxial Light Concentration and Homogeneously Trapped Two-Dimensional Optical Quantum Gases
(2022-07-15)
Trapped degenerate quantum gases in tailored environments allow for the investigation of otherwise unaccessible microscopic phenomena as they appear e.g. for the electron gas inside a solid. The field grew rapidly after ...
Strongly interacting few-body systems from lattice stochastic methods
(2020-08-04)
Lattice Monte Carlo plays an important role for non-perturbative descriptions of strong interactions.
Despite its success in recent years, some fundamental challenges remain.
Two of them are investigated in this work, ...
Polynomial Inflation and Its Aftermath
(2022-11-10)
Cosmic inflation elegantly resolves problems in the standard cosmology. The most simple inflationary theory invokes a single scalar field phi, slowly rolling down from a flat potential of a monomial form. However latest ...
Optimisation of the Data Reduction for the Belle II Pixel Detector and Development of a new Track Finding Algorithm using the Belle II Vertex Detector
(2023-05-15)
The Belle II experiment, located at the SuperKEKB collider in Tsukuba, Japan, is recording data at world record luminosities in order to provide world-leading results in the field of particle physics in the future. To ...
GLOSTAR: Investigating Tracers of Early High-Mass Star Formation
(2023-05-12)
High-mass stars (>8 msol) are not as numerous as their less massive counterparts but have a much more profound impact on their environment within their native galaxies. Despite their importance, our understanding of their ...
Baryon properties from chiral QCD
(2023-06-05)
This thesis contains a collection of studies on the properties of baryons within the context of effective field theory, especially Chiral Perturbation Theory. The thesis focuses primarily on the Roper resonance, an excited ...
Weiterentwicklung und Optimierung der Kontrolle der geschlossenen Gleichgewichtsbahn und des Modells der Elektronen-Stretcher-Anlage ELSA
(2023-04-17)
An der Beschleunigeranlage ELSA am Physikalischen Institut der Universität Bonn werden gegenwärtig zwei Experimente betrieben, welche die innere Struktur der Nukleonen untersuchen. ELSA zeichnet sich insbesondere durch die ...
Next-Generation Electronics for the Read-Out of Micro-Pattern Gaseous Detectors
(2023-04-20)
Developed by the RD51 collaboration, the Scalable Readout System (SRS) is widely used for the read-out of Micro-Pattern Gaseous Detectors (MPGDs). With different front-end Application-Specific Integrated Circuits (ASICs) ...
Machine learning approaches for adaptive optics in microscopy
(2023-05-08)
Microscopic imaging is an essential tool for science. For instruments that operate close to the physically possible diffraction limit, a main remaining challenge are aberrating operating conditions. For microscopy, such ...
