String theory has come under fire in recent years. Promises have been made that have not been lived up to. Leiden theoretical physicists have now for the first time used string theory to describe a physical phenomenon. Their discovery has been reported this week in 'Science'.

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.

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…

We use DNA strands to stabilize few-atom silver clusters, which show unique optical and chemical properties. This thesis involves the study of these constructs for various applications.

Louk Rademaker is visiting fellow at Leiden University, Lorentz Institute for Theoretical Physics. He studies theoretical quantum matter physics, connecting the material science to fundamental concepts and methods.

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.

The LED3 hub, consisting of researchers from the Leiden Institute of Chemistry (LIC), the Institute of Biology Leiden (IBL), the Leiden Academic Centre for Drug Research (LACDR) and the Leiden Institute of Advanced Computer Science (LIACS), is very excited to organize the “LED3 Lectures”. This lecture…

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…

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.

Everything you need to know about the minor American Studies.

The government is investing 646 million euros and has set aside a further 3.5 billion to drive economic growth in the Netherlands. Much of the National Growth Fund will be used for scientific innovations. Leiden University is involved in three of the projects.

On this page you will find an overview of awards and prizes granted to our staff and students in 2023, as well as special appointments at Leiden University and other institutions.

Truth is stranger than fiction. In 1997 Juan Maldaceña discovered a remarkable dictionary that translates equation for equation the physics of black holes in string theory into the more conventional physics of quantum mechanics of interacting particles. The remarkable possibility exists that…

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…

Majorana fermions in superconductors are the subgap quasiparticle excitations that are their own antiparticles.

The Research in Physics, Quantum Matter and Optics specialisation is an excellent stepping stone for pursuing a PhD degree.

Can we make quantum devices from quantum surprises? And can we explore and build life from the nanoscale up?

In this thesis, time-lapse fluorescent microscopy plays a pivotal role in investigating functional materials within living cells as well as the migratory behaviour of neural progenitor cells.

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.

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…

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…

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…

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…

Astronomers and surgeons from Leiden are collaborating with industry to develop an optical instrument that delivers faster, more accurate imaging of tumour tissue and abnormal blood flow during surgery.

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.

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…

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.

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.

The Physics and Quantum Matter and Optics specialisation is one of the two programmes Leiden offers in experimental physics. The programme can be tailored to individual needs and interests.

Kitesurfing, colonising the Binnenhof and most important of all - meeting fellow students. More then 700 students of Leiden University in The Hague get to know the city and one another during the HOPweek.

The correctness of computational systems is of great importance to our society, since it becomes ever more reliant on the benefits of computing.

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.

We investigate how radiation pressure can be used to influence the mechanical motion of a micro-mirror suspended from springs.

The mission of our group is understanding how science communication works to improve the interaction between science and society. We believe better science communication can improve our society and engage many different groups with science, also improving science.
