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 Master’s Open Day on 16 March was busy at all faculties in Leiden and The Hague. Thousands of visitors from the Netherlands and abroad came to Leiden University. ‘I want to find out more about the curriculum, and taste the atmosphere,’ said Sarah from Groningen.

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.

Single-molecule spectroscopy has become a powerful method for using organic fluorescent molecules in numerous applications.

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…

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…

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.

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…

Leiden scientists and companies receive 1.37 million euros to develop technology for the Einstein Telescope. This underground telescope will measure gravitational waves and must therefore be extremely sensitive. To that end, the consortium conducts research on the damping of vibrations at temperatures…

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…

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.

Classical and Mediterranean archaeologist Tymon de Haas is a relatively recent addition to the Faculty of Archaeology. Succeeding Tesse Stek in September 2018, he has played an important role in teaching since then, working together with colleagues from multiple research groups. ‘I have my corner of…

Matthias Flór receives the KHMW Graduation Prize in Theoretical Physics for his master's thesis. His research on exotic superconductors at Leiden University and TU Delft struck a chord with the jury. The jury unanimously chose to award Flór noting that ‘he demonstrated impressive technical abilities…

On Wednesday September 26th, theoretical physicist Sean Carroll will give an Ehrenfest colloquium. It is part of a lecture series that has been running since 1912 and was founded by physicist Paul Ehrenfest.

A collection of newly written chapters by various specialists from different disciplines (with a background in philosophy) on the subject of free will as it is discussed in their (inter)disciplinary field.
