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 programme offers you the ability to combine experimental research with theoretical courses. The programme helps you grow into an independent and skilled physicist.

Heterogeneous catalysis is one of the fundamental processes of modern life, being common in industrial refinery and hydrogen vehicles, all the way to the living cell. The dissociation of H2 on Cu(111) is an important benchmark system for studying heterogeneous catalysis, with a large and varied amount…

The specialisation consists of 120 European Credit Transfer System (EC) points and includes mandatory courses and electives (60 EC) and two research projects (60 EC).

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.

His Leiden honorary doctorate, the future of scientists, and diversity in science. Robbert Dijkgraaf tells about it in one of the classical rooms of the Academy Building. ‘It's very special, my honorary doctorate. A rare homage.’

From 16 to 26 July, the Leiden Institute of Physics organizes its annual summer school, titled ‘Modern Physics at all Scales’.

From July 22nd to August 1st, the Leiden Institute of Physics organizes its annual summer school, titled ‘Modern Physics at all Scales’.

On November 21, theoretical physicist Juan Maldacena gives the Ehrenfest Colloquium. Maldacena is known worldwide as the inventor of AdS/CFT correspondence, which might be key to a theory of quantum gravity. Maldacena is winner of the prestigious Dirac Prize and the Breakthrough Prize in Fundamental…

On 9 September, in the presence of King Willem Alexander, Secretary of State Sander Dekker presented the Spinoza Prize to four researchers, including two researchers from Leiden: archaeologist Corinne Hofman and physicist Dirk Bouwmeester. In the Nieuwe Kerk in The Hague, they unveiled their plans for…

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…

We are delighted to announce that the Digital Humanities and Artificial Intelligence minor will be offered in the 2024-2025 academic year with options of 15 EC or 30 EC packages.

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

The CIGR brings together a diverse range of unique expertise in genome research rooted in biology, chemistry and physics. Members of the CIGR investigate genome folding and genome transactions. An important aspect is direct as well as long term relevance for medicine. The available expertise extends…

Research in the Jawerth lab focuses on using principles from soft condensed matter physics to understand important biological materials.

Our group operates at the cross-roads of different disciplines: molecular and cellular microbiology, biochemistry, structural biology and biophysics. The group harbors expertise in a multitude of molecular and cellular approaches including:

The origin and evolution of galaxies are closely linked to many different physical phenomena.

Three of the four Heineken Young Scientists Awards for 2022 have gone to researchers from Leiden: chronobiologist Laura Kervezee, physicist Jordi Tura i Brugués and health psychologist Liesbeth van Vliet.

Proton therapy is a new way of treating cancer in which radiation doses are delivered more precisely. This results in less damage to surrounding tissue and fewer side effects. Professor Marco van Vulpen is medical director of HollandPTC in Delft, where the social value of this therapy is studied. Van…

Vibrating carbon monoxide molecules adsorbed at the surface of a salt crystal stop moving after a few milliseconds. Scientists now discovered this is dominantly due to the emission of electromagnetic waves. The role of the chemical bond at the surface thereby appears to be less important than previously…

In Leiden, light particles march into Wolfgang Löffler’s experiments one by one. His research focuses on acquiring the fundamental knowledge needed to develop quantum computers and networks.

On Saturday 19 November 2016 the students (9 – 12 years old) and several parents of the Transvaal University visited the Leiden University College (LUC) The Hague. The aim of the visit was to get acquainted with several scientific issues in an interactive session.

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 perspective addresses four challenges facing theorists whose aim is to make quantitatively accurate predictions for reactions of molecules on metal surfaces, and suggests ways of meeting these challenges, focusing on dissociative chemisorption reactions of H2, N2, and CH4.

We explore the particle physics and quantum world at the time of the big bang.

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…

For many a first-year, student life has well and truly begun. This also applies to students in The Hague, who were thrown in at the deep end during the HOP introduction week. We paid them a visit on a sunny afternoon at Landgoed Clingendael.

The focus will be on recent academic research in Literary Studies at the intersection with Digital Humanities. Lectures and interactive workshops will be given by experts in the field.

LUCDH facilitates workshops that promote the acquisition of skills and knowledge in employing digital tools.
