C.R. Hermans (2012). Facsimile-editie van Noordbrabants Oudheden aangevuld met enkele Archeologische Mengelwerken.

Research at the Leiden University Centre for Linguistics (LUCL) focuses on linguistic variation and diversity. In order to create more awareness and scientific understanding of this topic, research activities are clustered around six (overlapping) umbrella programmes. Many of our researchers are active…

The thesis describes experimental steps towards reduction of friction on the macroscopic scale by scenarios of thermo- and superlubricity well-known on the nanoscale.

Visualising structures of life

Optical cavities are useful tools to enhance the interaction between light and matter, which is important to make good quantum emitters. However, it turns out that the cavities themselves (without any quantum emitters) are already interesting objects to study.

In this thesis, we examine various systems through the lens of several numerical methods.

The dissertation describes TEM experiments on heterogeneous catalysts.

Direct radiocarbon dating of human remains is crucial for the accurate interpretation of prehistory. Yet given the scarcity of prehistoric human remains, direct dating is often too destructive for important fossils. The reduction of sample size necessary for dating bone is therefore of great interest…

e-SIDES (ethical and societal impact of data sciences) is a Coordination & Support Action (CSA) part of the Horizon 2020 programme.

How German Jews used photographs to document their experiences in the face of National Socialism.

A palaeogeographical reconstruction of Bronze Age West-Frisia (2000-800 BC)

This thesis presents the systematics, epidermal defense, and bioprospecting of wild orchids.

Opportunities, challenges, and future perspectives of people-centered approaches in dynamic historic urban landscapes

The changing status of anatomical collections from the early modern period to date.

This thesis consists of two subjects, that are both a consequence of radiation pressure.

Skandapurāṇa IV presents a critical edition of Adhyāyas 70-95 from the Skandapurāṇa , with an introduction and annotated English synopsis.

Mechanical interactions between cells and their environment play an important role in many biological processes.

The interest of this thesis lies in spin transport in normal metals and superconducting half-metallic junctions.

The first direct detection of gravitational waves opened the possibility of mapping the Universe via this new and independent messenger.

In this thesis, time-lapse fluorescent microscopy plays a pivotal role in investigating functional materials within living cells as well as the migratory behaviour of neural progenitor cells.

Make more fluid: In condensed matter systems, electrons can acquire unusual properties from their interaction with the atomic lattice.

My PhD research is devoted to studies of the conjectural cluster-algebraic symmetry in the theory of topological string, which is the simplest, however already non-trivial sector in the theory of string.

The thesis mainly contributes to the characterization of Majorana fermions as they appear in the Condensed Matter context.

In this thesis, classes of strongly interacting quantum field theories, have been studied.

The physics of black holes appears to be as far removed from the physics of electrons in metals as it can be.

In this thesis we use Josephson and noise scanning tunneling microscopy for the study of conventional, unconventional (iron-based) and disordered superconductors. On the one hand, Josephson scanning tunneling microscopy allows us to directly visualize the superfluid density with high spatial resolut…

In this thesis I describe the results of Pulsed Interleaved Excitation and Fluorescence (Cross) Correlation Spectroscopy (PIE-F(C)CS) combined with single-pair Förster Resonance Energy Transfer (spFRET) used to study dynamics in single nucleosomes, which depends on subtle differences in the length of…

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.

The studies in this thesis are focused on the physical effects in the flat band materials. The results contain the discovery of strong enhancement of RKKY spin-spin interactions with specific geometric arrangement and dynamical generation of excitonic order parameter with high magnitude.

Gold nanorods are biocompatible nanoparticles that present an excellent two-photon signal that can be used to get high spatial resolution inside living cells. Gold nanorods are photostable and therefore can be followed inside cells for long time, with possible applications as trackers in live cells.
