The research group ‘Quantum and Society’ explores the boundary between quantum technology and science communication.

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

The Tatiana Afanassjewa-lecture series is a series of public talks in Dutch by Leiden physicists on wednesday evenings, intended for everyone with an interest in physics.

If, as the works of John Cage suggest, there is “no such thing as silence,” then what are the markers that show us we are experiencing silence? - what are the performative cues during musical silence? - what are the auditory and visual bookends of silence in performance, i.e. what anticipates and…

Our group explores the larger domain of quantum measurement. In particular we investigate two themes that are closely connected: The detection of specially prepared quantum states of light and understanding and characterizing quantum photon detectors.

From October 2, ACPA alumnus and sound artist Budhaditya Chattopadhyay will exhibit his sound installation Expanded Object.

This project aims to situate the current policy concept of ‘valorization of scientific knowledge’ in historical and epistemological perspectives. Conceptual understanding of the utility of scientific practices is developed in dialogue with historical analyses of the politics of knowledge in European…

The central issue of this research concerns how students can best be supported in their study choice, study career and future orientation with a view to flexible entry and transitions and perspective in education and work.

The fourth volume of Ex Novo has the pleasure to host Heleen van Londen, Marjo J. Schlaman, and Andrea Travaglia as guest editors of the special issue titled The Natural and The Cultural. Integrating Approaches in Landscape Heritage Management. This timely collection of peer-reviewed papers and short…

Below some examples of ACPA projects that have a meaningful impact on arts and society. This page will be refreshed every now and then with other projects that exhibit how arts research bears upon our perception, our understanding, and our relationship to the world and other people.

Astronomers at ASTRON and Leiden University have used the LOFAR radio telescope to discover a 'brown dwarf' – a faint object more massive than Jupiter, but significantly less massive than the Sun. The discovery of the object dubbed Elegast, opens up a new path that uses radio telescopes to discover…

Speakers that have accepted to participate:

PhD student Thierry Rohmer received the Ernst Award 2009 of the Gesellschaft Deutscher Chemiker (GDCh) for his publication in the Proceedings of the National Academy of Science of the USA on the structure-function relation of the photoreceptor phytochrome. The prize was presented at the Annual Discussion…

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars, which are called exo-planets. They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems.…

Coordination chemistry is the chemistry of metal atoms

How do dissociative states affect the ability to suppress emotional distraction (in the context of a working memory task) in patients with Borderline Personality Disorder?

How does the photoregulation mechanism work in detail?

Bachelor projects are available in

In order to build wind turbines and electric cars, we need tons of magnets. Currently, we import these mainly from China, which means Europe is very dependent on this superpower for the energy transition. This has to change, according to industrial ecologist René Kleijn. In the REEsilience project,…

Theoretical physicists research a special class of particles; Weyl fermions. They have found them to exhibit paradoxical behavior, in contradiction to a thirty-year old fundamental theory in electromagnetism. A possible application is a new kind of electronics—spintronics. Publication in Physical Review…

An international team of researchers led by Leiden University (the Netherlands) has mapped nine gigantic collisions of galaxy clusters. The collisions took place seven billion years ago and could be observed because they accelerate particles to high speeds. It is the first time that collisions of such…

Last week, Joris Larik, Assistant Professor of Comparative, EU and International Law, was mentioned in an article by Euronews about the SWIFT ban.

The Journal of the LUCAS Graduate Conference was founded in 2013 to publish a selection of the best papers presented at the biennial LUCAS Graduate Conference, an international and interdisciplinary humanities conference organized by the Leiden University Centre for the Arts in Society (LUCAS). The…

Online services are stored on servers in data centres. Remko Fermin researched methods to make the memory in data centres more energy efficient.

What is dark matter? How do supermassive black holes form? ‘Primordial’ black holes might hold the answer to these long-standing questions. Leiden and Chinese cosmologists have identified a new way in which these hypothetical objects could be produced just after the Big Bang. Publication in Physical…

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…

Leiden physicist Maarten Kruithof has discovered how our DNA is infallibly able to fold itself and to unfold again. In his dissertation he demonstrates how DNA is folded in a single long, very flexible spiral.

Physics professor Jan Aarts starts a collaboration with chip manufacturer Intel to perform fundamental research in low-power, cryogenic computing.

Alzheimer’s disease is the most common form of dementia. This makes fundamental research on the precise cause of the illness of vital importance. One of the possible suspects is a certain protein filled with iron. Leiden physicist Lucia Bossoni (LION/LUMC) has now developed a new way of investigating…

The updated MRI scanner at the Leiden Institute for Brain and Cognition (LIBC) will become operational on 29 September. The new version is faster and better than the current model.

A Dutch-Italian-German team of astronomers has observed a huge glow of radio emission around a cluster of thousands of galaxies. They combined data from thousands of LOFAR antennas that were focused for 18 nights on an area the size of four full moons. This is the first time astronomers have been able…

Central in coordination and organometallic chemistry is the synthesis of new chelating ligands, the synthesis and characterization of metal complexes with these ligands, and the study of their properties. An important goal in my research is to create understanding of the relation between the structures…

This project looks at the current practices of marriage law in Indonesia. It examines the often ambiguous views different groups hold of marriage, from local villagers in Bengkulu to women’s activists in Jakarta, and how these relate to the development of national law on the one hand and local practices…

How can we quantify the density of species within a community through environmental DNA concentrations?

Chemical reactions go hand-in-hand with an energy exchange with the environment in which they take place. Surfaces offer a variety of energy dissipation channels, constituted by the nuclear and electronic degrees of freedom of the atoms at the interface. Aiming at an improved future harvesting of energy,…
