On the coexistence of Landau levels and superconductivity
In unconventional high temperature superconductors, supercurrent vortices are known to spoil the Landau levels. In this thesis the emergence of Landau levels is studied in different types of superconductors: Weyl superconductors, and the Fu-Kane heterostructure.

Slimmer omgaan met energie en materialen
De wereldbevolking is in de afgelopen eeuw exponentieel gegroeid, en daarmee ook onze behoefte aan energie en materialen. Willen we in de toekomst ook in welvaart leven, dan zullen we onze economie en consumptie radicaal anders moeten inrichten. Wetenschappelijk onderzoek laat zien hoe dat kan.

Strategies for braiding and ground state preparation in digital quantum hardware
With the help of quantum mechanics, digital quantum hardware may be able to tackle some of the problems that are too difficult for ordinary computers. But despite these expectations and the ongoing effort of the research community, reliable quantum computers are not yet realized in a lab setting.

Stock-driven Scenarios on Global Material Demand
The role of material production as a driver of environmental impacts is increasing, which calls for a better understanding of global material flows. This thesis explores the role of in-use stocks of products, buildings and infrastructure as a key driver of global material demand and discusses the implications…
