Der Einfluss von diskreter Diffusion auf die Dynamik eines minimalen nichtlinearen Systems gekoppelter Oszillatoren

The task of this theoretical bachelor thesis will be to expand our current model of Stuart-
Landau oscillators by implementing one or more models of discretized diff usion
between these oscillators. The model should be capable of meaningfully covering
the case of as few as four oscillators. Results will be compared with already
existing results obtained in the MCGLE and in the ensemble of Stuart-Landau
oscillators without di ffusion. As all relevant already existing code is written in
Python, some knowledge of this programming language is recommended.

Die Dynamik global-gekoppelter Stuart-Landau Oszillatoren

Coupled oscillators appear in many physical and biological systems, such as firing neurons in the brain or the pulsation of the human heart.
If the coupling diffuses fast, it can be approximated through a global coupling, and, as the simplest form, through the mean of the oscillator ensemble. It is known that such a coupling can lead
to a large variety of different dynamical states, such as secondary oscillations, clustering, chaotic dynamics or 'partial' chaos.
However, even the case of two mean-coupled oscillators is not well understood. Using two limit-cycle oscillators and coupling them through the mean field, the objective of this thesis is to find
all bifurcations occurring in such a system. We believe that those bifurcations are universal in the sense that they will also appear in larger ensembles of coupled oscillators, facilitating the understanding of coupled oscillators in general. Therefore, the results of two mean-coupled oscillators can then be extended to larger ensembles.

Requirements for this thesis are a basic understanding of nonlinear dynamics and a solid background in PYTHON. In addition, since many bifurcations cannot be obtained analytically, numerical continuation software such as AUTO has to be exploited, which requires some basic programming skills.

Photoelektrochemische Reduktion von CO2 an Gold/Kupfer-nanostrukturierten Siliziumelektroden

The photoelectrochemical conversion of CO2 to solar fuels is a promising way to address the challenge of renewable energy provision in future. Depending on the catalyst and the electrochemical environment, the products of the electrochemical CO2 reduction reaction are diverse. The aim of this bachelor thesis is to investigate the influence of different electrolytes on the electrochemical and catalytic behavior of silicon electrodes modified with gold/copper nanostructures. This will cover electrochemical methods, such as cyclic voltammetry and impedance spectroscopy, and product analysis using gas chromatography.
