This thesis presents the results of a study on the interfaces of insulating oxides with and without the insertion of a magnetic layer.

This thesis describes how to scale down concepts of macroscopic mechanical metamaterials to the thermal scale using a system of flexibly-linked colloids.

Advanced sensing techniques require graphene with high quality and well-controlled surface chemistry.

In this work, we investigate the minute circular dichroism effects of single nanoparticles.To this aim, we apply photothermal imaging with a polarization-modulated heating beam.

Op 3 juni 2016, werd het Symposium on International Investment Law as a Field for Scholarly Research georganiseerd door Uppsala University, samen met het Nordic Network on Investment Law en het Swedish Institute of International Law.

Een belangrijke puzzel in de astrochemie is opgelost: theoretisch chemici en astronomen zijn erin geslaagd te bepalen hoe ze met methanol magneetvelden in de ruimte kunnen meten. Dit geeft een nieuwe methode om de geboorte van sterren en planeten te onderzoeken. De onderzoekers, onder wie Leids hoogleraar…

Een Nederlands-Italiaans-Duits team van sterrenkundigen heeft een enorme gloed van radiostraling waargenomen rond een cluster van duizenden sterrenstelsels. Hiervoor richtten ze achttien nachten lang duizenden LOFAR-antennes op een gebied ter grootte van vier volle manen. Het is voor het eerst dat sterrenkundigen…

One of the most important correlation functions in physics, especially in cosmology, is the energy density, which describes how much energy is present at each point in spacetime due to matter fields. A key contribution to the energy density of the primordial universe comes from gravitational waves (GWs),…

In this dissertation, we work towards an experiment in which we aim to bring a micrometer sized magnet at the tip of a soft cantilever into a superposition.

Nature uses a special class of histone proteins, histone variants, to modulate the properties of chromatin at defined genomic locations.

The main focus of this thesis is the behaviour of two-dimensional materials, namely (anti)-ferromagnetic materials in the first two chapters, which show topological phases, and energetic square ice in the third and fourth chapter.

This thesis focuses on developing wafer-scale two-dimensional (2D) materials by combining synthesis, transfer, characterization, and device integration of graphene, hexagonal boron nitride (h-BN), and BN-doped amorphous carbon.

This thesis provides an overview of the development of the Pair Configuration to Molecular Activity Coefficient (PAC-MAC) model.

The unit residue group, to which the present thesis is devoted, is defined using the norm-residue symbol, which Hilbert introduced into algebraic number theory in 1897.

In the early universe, the dynamics of the Higgs field can give rise to many interesting phenomena.

Let A be a commutative algebraic group over a field K, and let G be a finitely generated subgroup of the K-rational points of A. The purpose of this thesis is to study the degrees of the Kummer extensions relative to A,K and G.

Op vrijdag 25 mei is de oratie van Tjerk Oosterkamp over zijn leeropdracht 'Experimentele Natuurkunde'.

Metal complexes and 2D materials like graphene were combined to produce structures that can function as sensors.

This thesis explores interfacial conductance and electric field-effects in LaAlO3/SrTiO3 heterostructures.

Onder supervisie van Dr. Mike Field wordt in Botanisch Laboratorium onderzoek gedaan naar archaïsch en paleo-botanisch materiaal, waaronder zaden en vruchten, pollen en sporen, en hout.

In this thesis we push the boundaries of high-resolution imaging at radio frequencies between 100 and 200 MHz. Using the International LOFAR Telescope that spans across Europe we achieve sub-arcsecond angular resolution.

The major and ultimate aim of metabolomics is to obtain an answer to a specific biological or clinical question.

This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.

In this thesis, we study systems of electrons in which strong correlations give rise to emergent exotic physics.

AI Labs zijn samenwerkingen van de Universiteit Leiden met externe partner zoals bedrijven, overheidsinstellingen en andere universiteit op het gebied van kunstmatige intelligentie. De Faculteit voor Wis-en Natuurkunde is uniek gesitueerd op het grootste Bioscience Park van Nederlands, en ligt direct…

Geometric phases lead to a nontrivial interference result when an electron's different quantum mechanical paths choices encircle a magnetic coil in an Aharonov-Bohm experiment.

All life on earth contains DNA, which is used to store biological information. Organisms compact their DNA in order for it to fit inside their cell(s).

This thesis consists of three chapters, the first two of which concern division points of elements of the multiplicative group of a number field.

This thesis consists of three chapters. Each chapter is on a different subject. However, all three chapters address issues that arise in counting arithmetically interesting objects.

De Faculteit der Archeologie van de Universiteit Leiden, Archol en Gemeente Oss werken al tientallen jaren samen. In 2021 is er een project opgestart om veldonderzoek uit te voeren in Oss. Dit project heet Field School, waarbij een groep studenten, docenten van de Universiteit Leiden en medewerkers…

Soil biodiversity is of great importance for the maintenance of multifunctionality in terrestrial ecosystems.

Data Science (DS) and Artificial Intelligence (AI) are omni-present and have the potential to be incorporated in various fields. However, in order to live up to this expectation, a good understanding of the techniques, their implications and limitations is required. In this minor you develop insights…
