Statistical optics methods for generating, simulating, and characterising emission from relativistic electron beams
[DESY-THESIS-2025-008]
Hamburg : Verlag Deutsches Elektronen-Synchrotron DESY, DESY-THESIS 172 pp. (2024) [10.3204/PUBDB-2025-01590]2024 = Dissertation, Universität Hamburg, 2025
Synchrotron radiation sources and free-electron lasers have revolutionised the study of matter and biological systems by providing unique combinations of radiation pulse characteristics. Although these two types of facilities differ fundamentally in terms of pulses time scales, coherence properties, and (peak) brilliance, each offers an exceptional mix of these features. [...]

Scintillating Nanocomposites Based on Lead Halide Perovskite Nanocrystals
123 pp. (2025)2025 = Dissertation, Scuola Di Dottorato Universita Degli Studi Di Milano-Bicocca, 2023/2024
In recent years, perovskite nanocrystals (CsPbX3, with X = Cl, Br, I) have emerged as a new class of materials for photonic and optoelectronic applications due to their exceptional synthetic scalability through solution-based processes, room-temperature fabrication and remarkable physical properties such as high emission efficiency and defect tolerance. Additionally, these materials possess tunable optical properties through controlled adjustments of their size and composition. [...]

Development of a tuneable few-femtosecond ultraviolet source up to 50 kHz repetition rate
Ultraviolet (UV) light plays a crucial role across various scientific fields such as biochemistry, material science and nanotechnology. Producing and using UV pulses with sub-5 fs durations is extremely demanding, but offers new possibilities for studying electron dynamics in light-induced biochemical re- actions.This thesis presents a tuneable ultrafast UV source operating at high repetition rates (up to 50 kHz), designed to be the key component of a table-top few-femtosecond UV-pump and IR-probe beamline to perform time-resolved spectroscopy measurements. [...]

Consistency, Robustness and Sparsity for Learning Algorithms
FAU 217 pp. (2024) [10.25593/OPEN-FAU-522]2024 = Dissertation, Friedrich-Alexander-Universität Erlangen-Nürnberg, 2024
This thesis is concerned with consistency, robustness and sparsity of supervised and semi-supervised learning algorithms. For the latter, we consider the so-called Lipschitz learning task (Nadler, Boaz, Nathan Srebro, and Xueyuan Zhou. [...]
