Many important topics in computer science, such as the correctness of software, the efficiency of algorithms and the modeling of complicated systems, depend on sound theoretical underpinnings. In the Theory group, we study these fundamental building blocks and develop verification methods to prove system…

What physics controls the properties of quantum matter, such as how electrons flow inside high-temperature superconductors? This question has captivated the physics community and industry for decades, in part due to the great technological potential such materials have, but also because they have resisted…

The programme guarantees a thorough experience on the frontline of physics research with a practical training of communicative and computer skills.

Our world is shrinking, or at least our electronic devices are. From PCs to mobile phones: everything is smaller and thinner. The smaller the chip, the better it can conduct electricity and pass on information.

The programme guarantees a thorough experience on the frontlines of physics research AND data science. It focuses on research areas where these fields overlap and in the process provides practical training of communicative and computer skills.

In this thesis we study quantum transport phenomena on the nanometer scale, in two classes of materials: topological insulators with induced superconductivity and graphene superlattices.

Jan Zaanen, Professor in Theoretical Physics of condensed material, has been awarded a Spinoza prize. His pioneering ideas about the collective behaviour of quantum particles and high temperature superconductivity have often given him the reputation of being something of a rebel.

Research at the Leiden Institute of Physics (LION) is foundational and curiosity driven. All our scientists share a desire to increase the knowledge of the world around us, in an open atmosphere of inquiry from which innovative ideas emerge that provide applications and value for society.

To strenghten ties with the public, press, other academics and wider society, LION employs an outreach officer.

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

When the government introduced its corona measures, the future of EL CID suddenly looked uncertain. But this annual introduction week will start on 5 August after all. How did the EL CID board pull this off? A glimpse behind the scenes through the eyes of chair Mirte Haanappel.

Carlo Beenakker has been appointed a Fellow of the American Association for the Advancement of Science (AAAS), the organisation behind the journal Science. Among the Fellows, he is the third Dutch person and first Leiden researcher.

This thesis describes the use of bioorthogonal proteins in immunological settings. It provides an introduction towards the field of protein modification, which was used throughout the thesis for the expression of proteins containing unnatural amino acids.

In the Netherlands, people probably grew up with De Fabeltjeskrant (a children’s show, ed.), but in France an introduction to fables plays a much more important role in a child's upbringing. PhD candidate Céline Zaepffel studied the role of fables in French education and teaching methods. It turns out…

The LED3 hub, consisting of researchers from the Leiden Institute of Chemistry (LIC), the Institute of Biology Leiden (IBL) and the Leiden Academic Centre for Drug Research (LACDR), is very excited to organize the “LED3 Lectures”. This lecture series brings world-leading researchers in the field of…

On 11 December Armin Cuyvers, Associate Professor European Law at the Europa Institute of Leiden Law School, was a studio guest on the news programme EenVandaag to talk about the possible scenarios for Brexit.

Leiden physicists have created a light source that emits individual particles in an identical state through optical fibers. Using this setup, their measurements can last longer and are more efficient, meaning they can perform more in-depth research on bizarre quantum effects, such as interference and…

Conferences, Workshops and Lectures showcasing research and tools in Digital Humanities.

For the International Day of Women and Girls in Science, women students and researchers from physics talk about what inspires them about their work. From quantum to cosmology and biophysics, their curiosity about how nature works is what connects these women. What do these 5 scientists want to share…

The master's specialisation Bioinformatics at Leiden University focuses on research, development and application of computational tools and approaches for expanding the use of biological, medical, behavioral and health data.

Workshop

If you replace the standard hydrogen atoms in ice with a heavier variant, something odd happens. The volume occupied by the molecules increases by 0.1 per cent. Leiden chemist Jörg Meyer and his colleagues have created a theoretical model that describes this behaviour. Their research appeared on the…

For many years, he was active in various management positions at the LION and even after his retirement he is still very involved. Professor Jan Aarts leads the Leiden hub of the Quantum Delta NL growth fund and is now temporarily responsible for national educational activities. In this way, he is helping…

Niels Laurens (37) has been appointed Executive Director at the Faculty of Governance and Global Affairs since 1 October. Because of covid 19, he only saw most of his colleagues within the faculty through a screen. Although the online introductions go well for him, Niels Laurens lacks personal contact…

Cryptographer Max Fillinger developed new methods to analyse a group of algorithms called commitments schemes. These schemes are building blocks for cryptographic protocols, which enable multiple parties that do not trust each other to work together safely. His PhD Defence is on 19 March.

Two Leiden Science researchers received an NWO-XS grant for their research. Both projects are highly promising, but also high-risk. Macrophages that trap bacteria and data storage made from 2D materials convinced the board of their potential.
