Our cantilevers have a low intrinsic damping rate: this enables us to measure with low noise, since damping is proportionate to noise. However, when the magnet is close to the surface of a sample we want to study, we measure a much higher effective damping rate. This is caused by magnetic interaction…

A plasma is an ionized gas with very low electrical resistivity. As such, magnetic field lines are 'frozen in' and move with the fluid. Magnetic field lines that are linked, knotted and tangled, cannot be undone by the fluid motions.

All PhD candidates must be admitted to the Graduate School.

On these pages you will find information on the research that is being conducted at each of the participating universities as well as the funding programme set up by the Research School.

In theory, states can gain security by acquiring internal arms or external allies. Yet the empirical literature offers mixed findings: some studies find arms and allies to be substitutes, while others find them to be complements. Political scientists Matthew Digiuseppe (Leiden University) and Paul Poast…

The ASCL Research Programme for the years 2019-2024 is called ‘Strident Africa: Societal and Environmental Change in the Context of 50 Centuries of History’. It examines the dramatic changes taking place on the continent in terms of population growth, urbanization, the role of external actors and the…

North Korean workers designed and built numerous monuments, museums and other buildings in southern Africa. This is clear from research by history student Tycho van der Hoog for his master's thesis. These monuments can be an important source of income for a country that has become quite isolated on…

One of the recurring points of discussion within the Criminal Justice research programme is the question of what behaviour should or should not fall within the scope of criminal law. This research theme is examined from a legal-dogmatic and social-scientific perspective.

EUMOTIONS explores the role of emotions expressed by political elites (at EU- and member state-level) in framing the EU’s policy options during international crises.

The external tissues of plants and animals are colonized by microbial communities termed microbiota. When organisms are exposed to environmental pollutants, these substances will therefore encounter microbiota at the exposure interface.

The Leiden University Graduate School of Archaeology (GSA) coordinates the admission and registration procedures of all PhD candidates with a PhD graduation planned at the Faculty of Archaeology. The GSA monitors the whole PhD track, from admission to graduation, supports (financially) both PhD ‘bottom…

This dissertation investigates A'-dependencies in Standard German, Zurich German and Dutch where the dislocated constituent is indirectly, i.e. not transformationally, related to the position where it is interpreted. The analysis is carried out within the Principles & Parameters framework.
