Het onderzoek van eLaw sluit vooral (maar niet uitsluitend) aan bij het facultaire onderzoeksprogramma Effective Protection of Fundamental Rights in a Pluralist World. De centrale onderzoeksvraag van dit programma is: welke kansen en bedreigingen vloeien voort uit de institutionele en normatieve diversiteit…

In this thesis we study bistable reaction-diffusion equations on lattice domains.

The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.

What impact does a mid-season wildfire have on grassland invertebrates?

Galaxies form and evolve through close interaction with their surroundings. As a result, the heavy elements ('metals') that are synthesized in stars, are found both inside and outside galaxies.

Het gebruik van ‘Big data’ is niet meer weg te denken binnen het wetenschappelijk onderzoek. Voor dit onderzoek maken we gebruiken van diverse grote databestanden.

We study the interplay of topology and geometry with chirality for several passive and active systems, employing both analytical and numerical methods.

n this PhD thesis, the recombination of different atomic lattices in stacked 2D materials such as twisted bilayer graphene is studied. Using the different possibilities of Low-Energy Electron Microscopy (LEEM), the domain forming between the two atomic layers with small differences is studied.

Thermodynamics is one of the founding scientific pillars that has helped us better understand heat engines, biology, ecosystems, and even black holes. While it fundamentally describes large systems by examining the bulk behavior of their constituents, it is anchored in the statistical equivalence of…

Ice, the solid state of water, plays an important role on our planet as well as the entire universe.Despite the fact that an individual water molecule has a very simple structure, its chemical bonding in the solid phase can be surprisingly complex.

Organisms often need to adapt more efficiently and devise new strategies for surviving difficult ecological circumstances.

Binnen het brede netwerk van de Universiteit Leiden neemt het instituut deel aan onderzoek binnen de volgende profileringsgebieden:

The haplolepideous mosses (Dicranidae) comprise about 4000 species distributed over a wide range of habitats, with great gametophytic and sporophytic morphological variation. Their monophyly is well supported by the results of several molecular phylogenetic studies, which shed light on their relationships…

De hersenontwikkeling van kinderen met een extra X chromosoom in vergelijking met kinderen met idiopathisch autisme: inzicht vanuit MRI onderzoek

The growing demand of energy indicates that global energy resources in the form of fossil fuels will not be sufficient in the future. In order to solve potential future energy problems development of a sustainable hydrogen economy is highly desirable.

In condensed matter systems electron-electron interactions, negligible in everyday metals, can dramatically alter the electronic behavior of the system. Examples of such altered behavior include high-temperature superconductivity and modulation of the electron density.

An interdisciplinary collection of the best international scholarship on Muslim youth.

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.

Of all the mass in our Universe, 80% is thought to consist of a hypothetical and invisible substance called dark matter (DM).

Parkinson's disease is the second most common neurodegenerative disease in the world. One of its symptoms is the loss of dopaminergic neurons in the substantia nigra pars compacta.

De nieuwbouw voor de Faculteit der Wiskunde en Natuurwetenschappen is een belangrijke mijlpaal voor de Universiteit Leiden en de faculteit in het bijzonder. In drie fasen wordt een nieuw gebouw gerealiseerd. De eerste fase van het nieuwe gebouw is in 2016 in gebruik genomen en beslaat 45.000m2. Het…

Can we develop a platform for raw materials intelligence?

In this Ph.D. thesis we study the interaction of low energy electrons with thin materials, namely layered materials (graphene, hexagonal boron nitride, molybdenum disulfide) and organic films. At these low energies the quantum mechanical wavelength of the electron wave function is in the order of a…
