Rare-earth materials are prime candidates for storing quantum information, because the undesirable interaction with their environment is extremely weak. Consequently however, this lack of interaction implies a very small response to light, making it hard to read and write data. Leiden physicists have…

The worldwide race to the quantum computer is in full swing. This computer can bring about a breakthrough in discovering medicines and new materials. Leiden researchers, together with the TU Delft, are taking part in the race. There is now a dossier online about their work.

In this thesis, classes of strongly interacting quantum field theories, have been studied.

Koen Bastiaans and his colleagues discovered a new quantum liquid unlike anything ever seen. They did it by using a technique that can be compared to listening to the sound of raindrops falling on a roof. Publication in Science 29 October.

MRFM combines the principles of magnetic resonance and atomic force microscopy.

Are you in a position of talent coach, coordinator, mentor, dean, or teacher and looking for university programmes that provide an extra challenge for the students of your school? The Leiden University Honours Academy provides such a programme, where vwo-students from the final three years of high school…

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

Are Weyl particles the ideal conductors? Do cells without a cell wall play a role in chronic Tuberculosis infections? Carlo Beenakker and Dennis Claessen want to answer these questions. They both received a KLEIN grant from the NWO. With these grants, NWO wants to stimulate innovative, fundamental r…

In what way can the chemical properties of cobalt porphyrines be adjusted to optimize their selectivity and activity when using them for the electrochemical conversion of CO2 to methane and methanol?

Four scientists from Leiden University have each been awarded a Starting Grant by the European Research Council (ERC). This grant, worth up to two million euros, gives researchers the opportunity to head up a research team for five years.

The Joan van der Waals colloquium is an ongoing bi-weekly lecture series.

Leiden alumnus and writer Tomas Lieske has published a novel which is set in the house of Paul Ehrenfest. Ehrenfest was a famous physicist who organized round table events every Wednesday evening at his home in Leiden in the early twentieth century. The big names from modern physics frequented these…

This year, two Leiden physicists have earned a prestigious ERC Starting Grant. With a budget of 1.5 million euros, this is one of the largest individual grants for scientists.

Heterogeneous catalyzed processes are highly significant to the chemical industry. Dissociative chemisorption (DC) of molecules on surfaces is always considered as a step with a high degree of rate control for heterogeneous catalysis.

In unconventional high temperature superconductors, supercurrent vortices are known to spoil the Landau levels. In this thesis the emergence of Landau levels is studied in different types of superconductors: Weyl superconductors, and the Fu-Kane heterostructure.

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'.

Special amplifying agents can make MRI scanners and NMR techniques hundreds of times more sensitive. Leiden physicists have now found a method to test their efficiency. More sensitive MRI scans could for example improve our understanding of cystic fibrosis or Parkinson’s disease. Publication in PCCP…

On the 2nd of June, Valentina Carraro gave a lecture on the complementarity of human rights reviewing mechanisms in the United Nations and presented an original framework to assess the extent to which institutions within regime complexes repeat or contradict each other when delivering recommendations…

In some condensed matter systems, such as the surface of a 3D topological insulator, the electrons are effectively massless and we must necessarily use the massless Dirac equation to describe them.

This thesis studies the geometry of representation varieties and character stacks. These are spaces parametrizing the representations of a finitely generated group, typically the fundamental group of a compact manifold, into an algebraic group G.

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

Prof. Dr. Richard Gill has recently joined as a member of the Foundational Questions Institute (FQXi). FQXi is an international association of scientists who explore the foundations of physics and cosmology.

NWO has assigned Physics Vrije Programma grants to five collaborations of physicists. Leiden University is involved in three of them.

In the spirit of 'unity in diversity', our objective is to promote insight into and appreciation for the wonder that the same physical laws and mathematical concepts apply to the whole of nature, from the largest to the smallest energy and length scales. We strive for the application of abstract theoretical…

Mechanical metamaterials have been found to display surprising features, on top of their unusual properties such as shape morphing and programmability. When the materials are a step in size larger, new rules seem to apply. This was discovered by researchers at AMOLF and the universities of Leiden and…

On Wednesday 5 June, Kalin Anev Janse, Secretary-General and Management Board Member of the European Stability Mechanism (ESM), was invited to give a lecture on 'Bridging decision-making: a new direction for Europe? Prioritising financial stability: the European Stability Mechanism and the Banking U…

Errors are everywhere, and mechanical failures are especially common: buckled grain silos and cracked support columns are, justly, seen as an issue to be avoided.

Leiden biophysicists have found a new possible way to attack cancer cells. They have located ‘sinkholes’ on the cells where receptor proteins disappear from the surface. If a drug could push these proteins towards those areas, it would kill the cancer cell.
