Electron Temperature Measurements in Discharge Capillaries [DESY-THESIS-2022-009] Hamburg : Verlag Deutsches Elektronen-Synchrotron DESY, DESY-THESIS 96 pp. (2022) [10.3204/PUBDB-2022-01913] = Masterarbeit, Universität Hamburg, 2022   The electron temperature of hydrogen and argon plasmas, that were produced at gas pressures of a few millibar and with electron densities in the range of $1\times10^{15} \text{cm}^{-3}$ to $1\times10^{17} \text{cm}^{-3}$, were investigated. These working points are typical of plasma sources which are used in beam-driven plasma wakefield accelerators such as FLASHForward.

Developing a low background method towards probing hydrated fibers and single molecules 67 pp. (2017) = Masterarbeit, University of Hamburg, 2017   Restricted: PDF PDF (PDFA); 2022-03-0216:31 [PUBDB-2022-01378] Master Thesis Marotzke, S. ; Gruebel, G. ; Rossnagel, K. Investigation of the magnetic and electronic properties of topological insulator/ferromagnet heterostructures 105 pp. (2022) = Masterarbeit, University of Hamburg, 2021   In recent years, the application of topological principles in physics has paved the way for the discovery of a wide range of topological materials with potential applications in spintronics, zero-resistance materials and quantum computing. Hereby, heterostructures with topological insulators (TIs) as one component and a magnetic material as another play an important role as new topological phases have been predicted in these systems.

Solution of the vibrational Schrödinger equation using neural networks 90 pp. (2022) = Masterarbeit, University of Hamburg, 2022   Two numerical methods using neural networks for the solution of the time independent Schrödinger equation are presented. The use of neural networks is motivated by the curse of dimensionality for classical methods. [...] Restricted: PDF PDF (PDFA) (additional files); 2022-02-1814:42 [PUBDB-2022-01262] Book/Master Thesis Togawa, M. ; Crespo Lopez-Urrutia, J. R. Investigation of the M-shell unresolved transition array of aluminium-like iron using monochromatic soft x-ray synchrotron radiation Heidelberg : Max-Planck-Institut für Kernphysik, Master Thesis, Ruprecht-Karls-Universität, Heidelberg 87 pp. (2021) = Masterarbeit, Heidelberg University, 2021   In various astrophysical observations, the n = 2 → 3 transitions of highly charged iron appear in the soft x-ray region as an unresolved transition array (UTA). The structure of the UTA is directly related to the ionization balance of the plasma and is therefore of high astrophysical interest.

Investigation of Stimulated Elastic Emission Using Soft X-Rays 55 pp. (2020) = Masterarbeit, University of Hamburg, 2020   Extremely bright, coherent and ultra-short pulses have become recently available thanks to theavailability of X-ray Free-Electron Laser sources. Such superior beam properties allow for thefirst time to investigate non-linear phenomena in the X-ray range.

Correlations of Structure and Dynamics in Dense ColloidalSystems 52 pp. (2021) = Masterarbeit, University of Hamburg, 2021   In this thesis the dynamics and higher order correlations of different colloidal sample systems are investigated at various volume fractions near the glass transition. Two different hard sphere and a charge stabilized system were studied [...] Restricted: PDF PDF (PDFA); 2022-01-1011:02 [PUBDB-2022-00097] Master Thesis Naab, R. ; Franckowiak, A. Search for short neutrino bursts with IceCube to trigger electromagnetic follow-up 71 pp. (2020) = Masterarbeit, Humboldt-Universität zu Berlin, 2020   The origin of cosmic rays has been a long standing puzzle in astrophysics. Cosmic accelerators are most likely also producing high-energy neutrinos, which are not deflected by magnetic fields and can potentially reveal these sources. [...] Restricted: PDF PDF (PDFA);
