The Physics and Biological and Soft Matter master's specialisation is one of the two programmes that Leiden University offers in experimental physics. This programme mainly focuses on Biological Physics and Soft Matters Physics.

The NET-ROL project builds on the EU's definition of the rule of law to investigate the role of networks in law-making, executive decision-making, and the judiciary. It examines how these networks influence the weakening of the rule of law. Through an interdisciplinary perspective, the project explores…

The project’s overall goal is to improve Indonesia’s environmental legal framework and its implementation by strengthening the regulatory capacity of the government, and by enhancing the capacity of CSOs and scholars to hold the government accountable for its regulatory performance.

Our research in the area of safety sciences aims to increase the mechanistic understanding of cellular toxicity of drugs and, in a broader sense, chemicals.

The master's specialisation Applied Cognitive Psychology consists of three main parts: the mandatory and elective courses, a thesis and an internship.

How do government officials and humanitarian organisations in Malawi anticipate and speculate on future disasters?

Leiden University Centre for Linguistics (LUCL) is one of seven institutes housed within the Faculty of Humanities.

How do we explain the fact that certain areas had many large cities, while other areas were studded with large numbers of small towns and yet other areas had very few urban agglomerations of any kind?

Urban riots, violent responses by police, drug-related assassinations, child abuse, bar fights: Violence is a core theme in today’s modern society.

In this study, we investigated the electrochemical behavior and surface evolution of Au(111) electrode under different conditions and electrochemical techniques, using a homemade electrochemical scanning tunneling microscope (EC-STM), revealing the intricate interplay between surface roughening, atom…

We co-organise our society through law and public institutions. As society evolves, these institutions continually face new dilemmas. Legislators must regulate AI while also fostering competitiveness. Judges are tasked with protecting a healthy environment while respecting democratic decisions. States…

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

Resilient Diversity: the Governance of Racial and Religious Plurality in the Dutch Empire, 1600-1800

PhD defence

The MSc IRD prepares you specifically for a career in international diplomacy, international government and non-governmental organisations, national or international public administration, ‘think tanks’ and research institutions, international interest associations or international business.

Connecting worlds, enhancing research and teaching, and providing innovative solutions to complex social issues: that is the idea behind interdisciplinary research. In that respect, a huge amount happened at Leiden University in 2023.

Why do we need fundamental science? For a lot of reasons, speakers showed at the Lustrum Symposium ‘Science Matters’. This symposium was held on 18 March 2016 to celebrate the 200th anniversary of the Faculty of Science.

In 2021 many of our students and staff won fantastic prizes and were awarded important research grants. This is our traditional review of these successes as the end of one year marks the beginning of another.

More than 700 visitors got to know the Science Faculty during the Leiden Science Family Day. People of all ages could enjoy fascinating experiments, tours, interesting lectures, spectacular nitrogen shows and various workshops. It was an informative day with many (future) scientists, amazement and,…

Light reflects from a mirror, but where exactly does this reflection happen? Well, it depends, Martin van Exter and Corné Koks discovered. Their precise calculations, published in Optics Express, are important for designing optical cavities for quantum communication.

Want to find out how to assemble a human skeleton? Do you know what chemistry can be found around you? And are you easily fooled by fake news? Discover this and more at our Science Fair on 3 October.

The Italian physicist Andrea Morello is one of the pioneers of the quantum revolution. He is currently doing research at the University of New South Wales in Sydney, but cherishes his time as a PhD candidate in Leiden.

Mimicking photosynthesis to produce bioplastics sustainably and efficiently. Researchers from the Institute of Biology Leiden (IBL) and the Leiden Institute of Chemistry (LIC) will assess this new approach. ‘An exciting opportunity to explore a new, appealing research topic in a collaboration between…

Nature publishes an article on a paradoxical discovery in superconductivity. Physicists are searching for superconductivity at high temperatures so that less cooling is needed in for example MRI machines. News & Views article by Prof. Jan Zaanen in the same issue of August 19th.

There are many complex links in the chain that provides patients with new drugs: from fundamental science, to clinical tests, to production. The entire chain can be found in Leiden. Leiden University, the Leiden University Medical Center (LUMC) and the businesses at the Leiden Bio Science Park (LBSP)…

Superconducting devices such as SQUIDS (Superconducting Quantum Interferometry Device) can perform ultra-sensitive measurements of magnetic fields. Leiden physicsts invented a method to 3D-print these and other superconducting devices in minutes.

NWO has granted Jan Aarts en Vadim Cheianov a Physics Projectruimte, a granting instrument for small-scale projects that propose innovative fundamental physics research that has a scientific, industrial or social urgency.

The behaviour of strongly correlated electron systems, such as high-temperature superconductors, defies explanation in the language of ordinary quantum theory. A seemingly unrelated area of physics, string theory, might give physicists a better understanding of the weird behaviour of these kinds of…

Christopher Berg Smiet, who defended his thesis at LION with Dirk Bouwmeester, won the Christiaan Huygens prize for his thesis '‘Knots in Plasma’. On 7 October, he received a certificate, a bronze statuette and ten thousand euros.

Leiden biophysicist Stefano Coppola has received the prestigious AXA Research Fund postdoctoral fellowship. With this grant he can work for two years on a project to research the role of mechanical factors in the development of pancreatic cancer.

Physicists Carlo Beenakker and Jan Aarts have been elected Fellows of the American Physical Society. Carlo Beenakker: 'People acknowledge your contribution, that is just very good to hear.'

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:
