Carmiggelt, J.J. (author)Knowledge about the magnetic and electronic properties of materials does not only expand our fundamental understanding of nature, but is also crucial for the development of new technologies. Today’s electronic devices rely on electrical currents to transport and process information, which generate a lot of heat waste via Joule heating. These...doctoral thesis 2023

(author)Highly uniform quantum systems are essential for the practical implementation of scalable quantum processors. While quantum dot spin qubits based on semiconductor technology are a promising platform for large-scale quantum computing, their small size makes them particularly sensitive to their local environment. Here, we present a method to...journal article 2023

Knepper, Jorian (author)The aerodynamic behaviour of a pitched baseball depends on the combination of the translational velocity, the rotational velocity in combination with the rotation axis and the seam positions. For small spin parameters the effect of seam positions dominates the Magnus effect. This study focusses on a visual understanding of the seam position by...master thesis 2022

Barbera, Matteo (author)Flying-wings show great potential for a vast number of applications, in both commercial and military sectors, thanks to their long range and fast forward flight, but suffer due to their lack of vertical take-off and landing capabilities. This paper presents a proof of concept for a novel landing method for a conventional flying wing that does...master thesis 2022

Elbertse, R.J.G. (author)This thesis describes atomic spin chains subject to magnetic anisotropy. Such chains, assembled through means of scanning tunneling microscopy (STM), can be home to a plethora of magnetic states and spin physics. This includes quantum tunneling of magnetization, the injection and delocalization of magnons and, for single atoms, the application...doctoral thesis 2022

Chaykina, D. (author)Rare-earth metal oxyhydride thin films show a photochromic effect, where their transparency decreases (reversibly) with exposure to light with energy greater than its optical band gap. The precise underlying mechanism behind this effect is unknown, but is investigated in this thesis by using techniques such as muon spin relaxation, or materials...doctoral thesis 2022

Ates, Matthijs (author)The aim of this thesis is to simulate quantum spin chains at a finite temperature. This has been achieved by using purification to write the incoherent thermal states of the spin chain as pure states, after which the matrix product state (MPS) formalism to simulate the spin chain. The influence of temperature on the spin chain has been tested by...bachelor thesis 2022

Gort, Timo (author)<i>Context.</i> In the near-future, exoplanets can be observed directly through telescopes. Although the resolution of the planet's image will only be one pixel at first, the intensity of this pixel will change over time because of the orbit around its host star and its diurnal rotation. This intensity as a function of time is called the light...bachelor thesis 2022

Blanken, Sweder (author)In the near future, next-generation telescopes will be able to observe Earth-like exoplanets illuminated by their parent stars for long periods of time. As the distance between exoplanet and observer is enormous, exoplanets will only make up a pixel on our image. However, the observed intensity of this pixel will fluctuate over time as the...bachelor thesis 2022
