Loss of cultural heritage first brings to mind the destruction in the Middle East. But in the Caribbean it is mainly natural processes such as coastal erosion and human interventions driven by economics that are damaging the local natural and cultural heritage. A conference is taking place on Bonaire…

Can we make quantum devices from quantum surprises? And can we explore and build life from the nanoscale up?

Digitally Preserving Heritage at Risk

The archaeological heritage of South America is facing increasing threats due to the expansion of agricultural activities, infrastructure expansion, illegal wood harvesting, and the current fire emergency plaguing the Amazon and other biomes of the continent.

The project aims to conserve and consolidate the entrance gate to the Roman Desert Frontier Fort Qasr Bshir.

On this page you will find an overview of awards and prizes granted to our staff and students in 2025, as well as special appointments at Leiden University and other institutions.

La Grande Roche is one of the rare archaeological sites that preserved a long sequence of deposits formed at the time of contact between late Neandertals and early Homo sapiens.

Aan de hand van bekende en minder bekende voorbeelden uit de wereld van politiek en media laat dit boek zien hoe je strategisch gebruik én misbruik kunt maken van taal.

Dit rapport maakt deel uit van het project Receptenboek burgerparticipatie in opdracht van de Rijksdienst voor het Cultureel Erfgoed (RCE) en met steun van het Fonds voor Cultuurparticipatie.

Where does the urge to collect come from? What are the explicit or underlying reasons for gathering large amount of objects?

Research combining a conceptual and practical perspective within the field of teaching and learning second languages.

European labour law has an unmistakable influence on national law. This applies even more to the case-law of the Court of Justice of the European Union (CJEU), as it has implications for the application of European law in the Member States and with it the interpretation of national law. Collected Cases…

World-class research is integral part of the master’s education. You obtain a Physics degree from an institute with an international reputation. Research in this programme is fundamental and curiosity-driven.

Physicists at the Leiden Institute of Physics (LION) conduct fundamental research into physical phenomena. They are inspired by curiosity and the desire to know more about the world in which we live. This research has always paved the way for new practical applications. These are something that the…

The Physics and SCS master specialisation gives you the opportunity to combine Physics research with different aspects of science communication.

The Physics and Education master specialisation gives you the opportunity to combine physics research with an excellent education in becoming a physics teacher.

LION offers a PhD program in which candidates carry out independent research on a specific topic, culminating in a PhD thesis.

The programme will give you the opportunity to choose from a broad range of topics to study. You will be part of an international multidisciplinary research team at the LION.

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

Cambridge University Press has published a new book co-authored by researchers from Leiden University, offering both an introduction to machine learning and deep neural networks, and an overview of their applications in quantum physics and chemistry — from reinforcement learning for controlling quantum…

PhD candidates carry out a programme of independent research and additional (limited) course work, culminating in production of a PhD thesis in typically 4 years.

This thesis described the development of novel scanning tunneling microscopy techniques to investigate strongly correlated electronic states in quantum matter.

Doctoral Thesis

Scientists, including our faculty colleague Dr. Mike Field, studying an exceptionally well-preserved woolly rhinoceros have revealed details of what Britain's environment was like 42,000 years ago. The beast's remains were discovered in Staffordshire in 2002, buried alongside other preserved organisms…

On October 9th, Peter Alexander Kerkhof succesfully defended his doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Peter Alexander on this great result.

The Cryogenics Department has a liquid helium production unit and an automatic liquid nitrogen filling plant.

I will give a general introduction to the field of molecular electronics, its history, methods and challenges. I will also introduce the subject of my investigation and provide a brief outlook to the remainder of our thesis.

In my thesis I study Majorana fermions from three different perspectives. The first one corresponds to non-interacting Majorana fermions that, however, pose non-trivial topological properties. The second one corresponds to strongly interacting Majoranas and the third to relic neutrinos. No one knows…

In the thesis we demonstrated an 85% state transfer efficiency between two mechanical modes coupled to a common optical mode via stimulated Raman adiabatic passage (STIRAP) in the classical regime. We also showed possibilities to manipulate quantum states of the mechanical modes via STIRAP.
