To mark the university’s 450th anniversary, the Leiden Discoveries science route has been updated and was relaunched on the Night of Discoveries. New signs in town and a revamped website tell Leiden residents and visitors the stories of the city’s spectacular discoveries.

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.

Is it possible to measure subtle oscillations caused by dark matter moving through the earth? A Dutch-American physicist team have discovered a new route toward what could be the first-ever measurement of ultralight dark matter. They suspended a microscopic magnet inside a superconducting enclosure,…

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.

Solar energy is used by photosynthetic organisms to drive energy required cellular processes. Is absorbed by two groups of pigments, located in the LHCs.

To argue that people can control the relative contributions of goal-driven and stimulus-driven processes to decision-making and action selection.

Prostate cancer (PCa) is one of the most prevalent cancer in males.

Exploring the mechanism of targeted nanoparticle-mediated drug delivery using the zebrafish model

Promotor: B. van de Water

This thesis focuses on the role of chemokine receptors CXCR3 and CCR2 in the inflammatory process and infection control using the zebrafish model.

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.

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

Cars are equipped with catalysts to disarm toxic exhaust gases. Platinum plays an important role there. Leiden physicists and chemists have now for the first time seen the mechanism behind a platinum catalyst. With a fundamental understanding of the process, scientists can use this rare material more…

‘Quantum technology is going to change the world, but most people don’t feel connected to it. I want to change that,’ says Julia Cramer, assistant professor at Leiden University. Known for her passion for science communication, Cramer actively seeks opportunities to share the wonders of quantum technology…

Designing innovative algorithms, thinking outside the box, and brainstorming over coffee with his colleagues — this is what physicist Stefano Polla enjoys most. His success shines through in his nomination for the C.J. Kok Jury Award 2024 for PhD thesis of the Year.

Lecture, Studium Generale

Vedran Dunjko (LIACS and applied Quantum algorithms (aQa) Leiden) and Tomoyuki Morimae (Kyoto University) are to collaborate with Qu&Co. Qu&Co is a leading European developer of quantum software.

Materials with strongly correlated electrons show some of the most mysterious and exotic phases of quantum matter, such as unconventional superconductivity, quantum criticality and strange metal phase.

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.

Research on quantum computers and Islamic charities: two Leiden researchers have received a Consolidator Grant from the European Research Council.

This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.

A suitcase as a messenger of quantum science. That is the idea behind QuanTour, a project connecting researchers from 12 European universities. In December, the suitcase landed in Leiden. A month later, it is time to pass the baton to Copenhagen. But what happened to it in Leiden?

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.

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'.

Former PhD, Bachelor and Master students of the Van Exter Lab

Scientists need individual photons for quantum cryptography and quantum computers. Leiden physicists have now experimentally demonstrated a new production method. Publication in Physical Review Letters on July 23rd.

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.

Five researchers from Leiden University have been awarded a Starting Grant by the European Research Council (ERC). This grant of on average 1.5m euros enables researchers who show potential to start their own project, lead a research team and implement their best ideas.
