In this dissertation, matching, entropy, holes and expansions come together. The first chapter is an introduction to ergodic theory and dynamical systems.

Lecture

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…

Physicist Remko Fermin from Leiden University was awarded a Rubicon grant from NWO. He will use it to study superconducting diodes that could contribute to reducing the CO2 emission of data centres.

Lecture

Research at the THEOR group is comprised of the following research themes:

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 Digital Humanities and Artificial Intelligence minor in the 2024-2025 academic year with options of 15 EC or 30 EC packages.

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).

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…

The project has been done in the Quantum Optics group under the supervision of Dr. Jan Willem Dalhuisen. The title of the presentation is: ''Hopfions in curved spacetime.

Experimental physicist Jan Aarts has received a FOM Projectruimte grant of 545,000 euro. He will use the budget to study the interaction between superconducting currents and ferromagnetism. In the future, this might lead to computer memory with negligible energy consumption.

The project has been done in the Quantum Matter Optics group under the supervision of Prof. dr. Tjerk Oosterkamp and Dr. L. Bossoni. The title of the presentation is:

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 ultimate goal of the PhD program is the preparation and successful defense of a PhD dissertation.

In this dissertation several settings in the Online Learning framework are studied. The first chapter serves as an introduction to the relevant settings in Online Learning and in the subsequent chapters new results and insights are given for both full-information and bandit information settings.

Leiden physicists have been awarded 1.5 million euros for developing a hybrid microscope that provided nanometer-resolution. 'The idea is to combine the resolution of electron microscopy with the pros of optical microscopes.'

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

This header image was once elected Image of the Week by De Volkskrant and won second place in the LION Image Award. The research behind it is no less successful if we’re counting prizes. Last August, group leader Tjerk Oosterkamp was awarded an NWO Projectruimte grant, and now NWO-TTW grants him an…

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

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

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…

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…

Research truly comes to life when it contributes meaningfully to society. By sharing our findings, advising policymakers or contributing to community projects – we can make a real impact. Scroll down and discover how Science and society can mutually benefit from each other.

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. Workshops are held in person, and rarely hybrid.

Because the last Elfstedentocht celebrates its twentieth anniversary, New Scientist spoke with physics professor Tjerk Oosterkamp about his research on the slipperiness of ice and his passion for skating on natural ice.

The project has been done in the Quantum Matter Optics group under the supervision of Dr.ir. Sense Jan van der Molen. The title of the presentation is: ''A Technique for Studying Surface Profiles of Two-Dimensional Materials in LEEM.

On Thursday 3 November, Leiden University celebrated the official opening of two wall formulas in the Leiden city centre. Snell's law and the formula for the Lorentz force shine on two walls in the heart of Leiden. TV channel Omroep West interviewed the initiators Sense Jan van der Molen and Ivo van…
