Since 2015 the United Nations have declared 11 February the International Day of Women and Girls in Science. Leiden University organized a public event for over a hundred visitors. In between a lecture on the building blocks of life and a talkshow on the impact of science on society, high school students…

This thesis aims to demonstrate how the achromatic nature and design flexibility of liquid-crystal optics can be used to improve high-contrast imaging instruments to facilitate detailed exoplanet characterization.

The application procedure is broken down into three parts.

By carrying out fundamental research and providing excellent education, universities become a breeding ground for innovation and entrepreneurship.

The Cyber Security Academy, therefore, proudly and enthusiastically announces that on 8 February the second cohort of Master of Science (MSc) graduates in Cyber Security in the Netherlands will graduate at the Campus of The Hague Security Delta (HSD), the national innovation centre in The Hague and…

With its FestivOWL theme, Orientation Week Leiden (OWL) promises to be one big festival for new international students in Leiden.

Moving an electron microscope of 2000 kg is a delicate challenge. The highly sensitive instrument needed to be moved to a new measurement hall, but even a tiny bump could damage it. After a few nerve-racking weeks of preparing the move and reinstalment, the researchers finally have a verdict: the instrument…

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.

Joanna Krenz defended her thesis on 15 May 2018.

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.

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

With increasing carbon dioxide levels in the atmosphere and their detrimental effect on the global climate, modern society needs to push for more renewable energy sources. Storing widely accessible and abundant solar energy in chemical bonds in the form of molecular fuel via artificial photosynthesis…

The research group Science Communication and Society aims to understand how science communication works to improve the interaction between science and society. Central themes are ‘Bridging the gap between experts and the general public’ and ‘Evaluating Science Communication’.

The theoretical explanation of cosmic acceleration is nowadays one of the biggest puzzles in cosmology.

Leiden University offers you several services related to career orientation and job application skills.

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…

The research of the Algebra, Geometry and Number Theory cluster tries to bridge the gap between abstract theory and the world of algorithms and applications.

In this thesis, we describe the latest advances in SQUID-detected Magnetic Resonance Force Microscopy (MRFM).

The Algorithms and Software Technology (AST) research programme performs fundamental research in the areas of algorithm design and analysis.

Artificial photosynthesis aims to produce fuels from solar energy using chemical processes. In semi-artificial photosynthesis, a hybrid approach is taken using both chemical and biotechnology approaches. We aim to develop hybrid systems between light-harvesting nanoparticles and redox-enzymes (oxidoreductases)…

In this thesis we study the landscape of gravitational models which modify GR by introducing an additional scalar degree of freedom (d.o.f.) to source Cosmic Acceleration.

The specialisation High-Tech Innovation is for MSc students in Sciences who are interested in interdisciplinary technologies and research related to /important for high technology industries, e.g. the semi-conductor industry or nano-fabrication. In addition to their primary field of study, students…

‘Leiden is small, friendly and welcoming,’ says new first-year student Ayla Russel. Strong wind and heavy showers were forecast for the first in-person day of the EL CID on 16 August, which could easily have spoiled this impression. But fortunately the showers – apart from one – fell somewhere else,…

Uniting an international consortium of scholars, the Skandapurāṇa Project comprises a team of researchers working in fields across the Humanities. We are creating a critical edition of a foundational work of purāṇic literature and, in doing so, tracing the dynamics of a textual tradition to better understand…

From a meaningless block of plastic to an advanced component that contributes to the energy transition. The technicians and scientists of our faculty think it out in detail and make it a reality. This special project shows that they need each other.

Following in the footsteps of Professor Jan Zaanen, visiting fellow Louk Rademaker is exploring quantum effects in so-called strange materials. His research is paving the way for new materials that could be used in emerging technologies.

Leiden physicists have developed a way to address how accurately a superconducting single photon detector (SSPD) can be characterized by detector tomography. SSPDs are not fully understood, and tomography is a key element to determine how these devices detect light. A better understanding of these detectors…

The International Reynard Society studies the role of animals in the European literature of the Middle Ages and its afterlife. It focuses especially on beast epics, fables, and fabliaux. The 24th international colloquium of the Society – Of Foxes and Fish: Interdisciplinary Approaches to Medieval Animal…

This week, around 1,200 brand new students from 68 different countries are getting to know each other and their new student city. Orientation Week Leiden (OWL) got off to a good start on sunny Lammermarkt, which was packed with enthusiastic internationals.

Thousands of first-year students and hundreds of mentors kicked off the EL CID on Monday morning. This year for the first time, the introduction week of Leiden University and Leiden University of Applied Sciences was also open for students of Regional Training Centre mboRijnland and the Leiden Instrument…

Complex research with a generous sprinkling of jargon: PhD defences can be difficult for non-experts to follow. In the compulsory new lay talk, PhD candidates begin by explaining their dissertation in words of one syllable. And it’s not just the PhD’s family and friends who appreciate this.

Ten years after its introduction, the controversial idea of Erik Verlinde on gravity is still a hotly debated topic, and is still surrounded by a cloud of scepticism. Scepticism in which the media have played a major role, theoretical physicst Koenraad Schalm says in an article by NWO. ‘The media simply…
