Ramdin, Keane (author)There has been interesting research on the superconducting diode recently. A possible structure for this is the Superconductor/Ferroelectric/Superconductor (S/FE/S) Josephson junction. Our goal is to simulate a S/FE/S junction with a magnetic field and see if this leads to a superconducting diode effect. First this junction and its properties...bachelor thesis 2023

Vermeer, Wiggert (author)Synchronisation refers to the tendency of coupled oscillators to move in phase with one another over time, departing from their own natural frequency. This phenomenon occurs in almost all branches of science, engineering, and social life. Synchronisation is a well understood concept in classical mechanics. Quantum synchronisation involves...bachelor thesis 2022

Witmer, Brian (author)Quantum technology is evolving faster than ever. Currently, all eyes are on the quantum computer, the promising computer that can solve problems which are unsolvable for regular computers. In order to understand this new technology, it is necessary to understand the qubit, the basic unit of quantum information. This can be done by means of the...bachelor thesis 2022

de Bos, Hidde (author)Quantum Markov Semigroups (QMS) describe the evolution of a quantum system by evolving a projection or density operator in time. QMS are generated by a generator obeying the wellknown Lindblad equation. However, this is a difficult equation. Therefore, the result that the Lindblad form greatly simplifies in the case of the...bachelor thesis 2021

La, Helena (author)Magnons are quanta of spin waves, i.e. modes of collectively precessing spins. Thermally excited magnons in thin magnetic films generate stray fields at the film surface which can be detected using nitrogenvacancy (NV) centers. NVs are lattice defects in diamond and are able to couple with magnon stray fields. Assuming a thermal occupancy of...master thesis 2021

Klijnjan, Tim (author)Synchronisation is the remarkable phenomenon of inphase movement of coupled oscillators during a prolonged period of time, which even occurs when these have different natural frequencies. This property is used in many fields like physics, biology and chemistry, to model various system behaviours, for instance: circadian rhythms in the chemistry...bachelor thesis 2021

Weerheim, M.W. (author)Complex quantum systems, such as a quantum computer, will always be coupled in some way to the environment. This can cause what's called decoherence, a destructive process by which information is lost from the system into the environment. In this bachelor thesis paper, we discuss decoherencefree subspaces within networks of coupled quantum...bachelor thesis 2020

Rou, J.G. (author)In this research a study of the response of a simply supported microbeam subject to an electric actuation is presented. A perturbation method called the method of multiple scales is explained and used to solve our problem. A model concerning the midplane stretching and an electric force with a direct and alternating current component is...bachelor thesis 2020

Kramers, Katja (author)This thesis analyzes the occurence of the quantum Zeno effect in a qubit in different situations. A system with a particle with spin 1/2, which represents a qubit, and detector is considered. The detector is modeled by a coordinate q, which has a Gaussian distribution with dispersion σ. There is the free evolution of the qubit and the...bachelor thesis 2019

van Dongen, Lotte (author)The dynamics of interacting manyparticle systems on quantum mechanical scale is a broad subject of research in modern physics. The understanding of the quantum correlations, or entanglement, between the particles in an isolated manybody quantum system may however be challenging, as the amount of interactions may be large. To be able to...bachelor thesis 2018

Laeven, T.M. (author)A theoretical analysis of the existing model for OMIT by Weis\cite{weis} is provided in language familiar to bachelor students. Most prominently, the influence of a fourth order nonlinear perturbation($K \Ad \Ad \A \A$) to the plain OMIT Hamiltonian is investigated numerically, for varying perturbation strength for the three coupling schemes;...bachelor thesis 2015
