Individuen die werken in de publieke sector zien zichzelf geconfronteerd worden met tegenstrijdige waarden, tegenstrijdige eisen en de noodzaak van het dienen van het soms moeilijk definieerbare publieke belang.

Quantum computing is an emerging technology, which holds the potential to simulate complex quantum systems beyond the reach of classical numerical methods.Despite recent formidable advancements in quantum hardware, constructing a quantum computer capable of performing useful calculations remains challenging.In…

Het Netherlands Centre for One Health (NCOH) is uitgebreid met de Universiteit Leiden en het LUMC. De komst van de Leidse instellingen versterkt het academische netwerk waarin onder andere het probleem van antimicrobiële resistentie wordt onderzocht.

This thesis aims to improve the detection from ultra-weak single emitter by enhancing their emission properties with plasmonic nanostructures. We exploit the wet-chemically synthesized single crystalline gold nanorods (GNRs) as our basic frameworks in the whole studies, simply because of their unique…

Oplossingen bedenken voor mondiale vraagstukken zoals milieuvervuiling en armoede. Dat doen jongeren die vanuit de hele wereld samenkomen op de top One Young World van 17 tot en met 20 oktober in Den Haag. Volg de Leidse studenten Jennifer Pfister en Thomas Gevers die verslag doen van hun ervaringen…

What determines civic engagement in transboundary hydropolitics and why has it been muted in the Eastern Nile Basin?

Researchers from the Department of Economics - Kees Goudswaard, Koen Caminada, Marike Knoef, Pierre Koning and Olaf van Vliet - have been awarded a grant of one million euros by Instituut Gak to investigate self-sufficiency and social protection.

Onze decaan Rick Lawson en Anette van Sandwijk, Hoofd Bureau Internationaal Onderwijs, reisden van 5 tot en met 16 april langs een aantal partners in de Verenigde Staten. Leiden Law School heeft al lange tijd samenwerkingsverbanden met een aantal vooraanstaande Amerikaanse Law Schools. Doel van de reis…

Anthropogenic change is reshaping ecological systems, raising concerns about increasing transmission of infectious diseases. Among these, mosquito-borne diseases may be particularly sensitive to environmental change, as their transmission depends on vector populations.

To an algebraic curve C over the complex numbers one can associate a non-negative integer g, the genus, as a measure of its complexity.

Our recent excavations have focused on the more recent New Kingdom/Late Period (ca. 1500-332 BCE) material.

All the data stored and processed by our computers is encoded as sequences of zeros and ones, called bits. Quantum computers offer an alternative to this traditional way of encoding and manipulating information.

Binnen Una Europa vindt academische samenwerking plaats in interdisciplinaire zelfsturende comités (SSC’s).

The physical origin of the dozens of stellar-mass binaries, the mergers of which have been detected by the LIGO-Virgo-KAGRA collaboration via gravitational waves, is still unknown.

The Standard Model (SM) of particle physics fails to explain several observed phenomena and is incomplete. In order to resolve this problem, one may extend the SM by adding new particles.

The four possible segments A, T, C and G that link together to form DNA molecules, and with their ordering encode genetic information, are not only different in name, but also in their physical and chemical properties.

This thesis focuses on the X-ray spectral analysis of merging galaxy clusters and the plasma code development for future high-resolution X-ray spectroscopy observations.

Hoe positioneerde onze academische gemeenschap zich ten opzichte van een systeem dat mensen van hun vrijheid beroofde? Welke rol heeft de universiteit als onderwijsinstelling ingenomen ten opzichte van kolonialisme en het slavernijsysteem? Hoe kunnen wij het beste omgaan met onze bijzondere collecti…

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.

Metabolomics has the potential to play a pivotal role in understanding disease onset and progression, and ultimately personalized treatments. One of its major challenges is its large-scale implementation, which is necessary to deal with the high variability of the metabolome. In this work we have developed…

On a structural level, the properties featured by a majority of mechanical metamaterials can be ascribed to the finite number of soft internal degrees-of freedom allowing for low-energy deformations.

Announcement of a new publication by Janneke Verheijen, lecturer at the Institute of Cultural Anthropology and Development Sociology.

In 2015, CML published over 70 papers, contributed to the United Nations conference on climate change in Paris, won awards and advised the Dutch government on the safe use of pesticides. CML awarded 11 PhDs and taught students from all over the world how to contribute to sustainability. We wish you…

Galaxy intrinsic alignments induce a major astrophysical contamination to weak gravitational lensing measurements and need to be modelled and mitigated when extracting cosmological information from such measurements.

Understanding interactions in quantum many-body systems remains one of the most profound and difficult challenges in condensed matter physics.

Op 28 oktober 2021 verdedigde Hein van der Bruggen zijn proefschrift en behaalde daarmee de doctorstitel.

Single-molecule spectroscopy has become a powerful method for using organic fluorescent molecules in numerous applications.

One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.
