The research program of the QO group has three leading themes: Optical Physics, Quantum Optics, and Photon-Matter Interactions. We work mostly at the boundaries between these themes with entanglement as a bridging and binding agent.

NVIC suffered a great loss by the passing of Dirk Huyge, curator of Prehistoric and Early Dynastic Egypt at the Art & History Museum, Brussels. Dirk Huyge will always be remembered for his role in establishing a systematic approach for rock art research in Egypt. May all the beautiful memories be…

Dirk Uittenbogaard, a student on the Delft-Leiden Master’s in Industrial Ecology, has won a gold medal for rowing at the Olympic Games in Tokyo. Uittenbogaard took gold in the men’s quadruple sculls, together with Abe Wiersma, Tone Wieten and Koen Metsemakers.

This year Dirk Visser will celebrate working at the faculty for 25 years. During this period he has progressed from being a student assistant to becoming an expert in information and copyright law in the Netherlands. This event will be marked with a symposium to be held on 2 September as part of the…

In a column on Mr. Online, Dirk Visser, Professor of Intellectual Property Law, looks at what You Tube is doing or should be doing to counter copyright infringements on the platform in a credible and effective manner.

On 9 September, in the presence of King Willem Alexander, Secretary of State Sander Dekker presented the Spinoza Prize to four researchers, including two researchers from Leiden: archaeologist Corinne Hofman and physicist Dirk Bouwmeester. In the Nieuwe Kerk in The Hague, they unveiled their plans for…

To tackle deepfakes, Denmark proposes expanding copyright law so everyone gets copyright over their own face and voice. There are similar ideas in the Netherlands with an online consultation. In Latvian newspaper ‘Latvijas Avīze’, Dirk Visser and Bart Custers discuss the proposals.

FSW Professor Jan Dirk Blom has written a book on Alice in Wonderland syndrome. This is the first scientific book on this rare disorder, which was first described in 1955 by the British psychiatrist John Todd. Todd was inspired by the famous book by Lewis Carroll, in which Alice experiences all kinds…

The aim of ANCIENT CHARM was to develop neutron-imaging techniques and the associated equipment, and help establish neutron imaging as a mainstream archaeological analytical technique. In particular, one of the goals was a new imaging technique which called neutron resonant capture imaging combined…

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.

The Tatiana Afanassjewa-lecture series was a series of public talks in Dutch that was started during the Covid-19 lockdown. The talks were given by Leiden physicists on wednesday evenings, intended for everyone with an interest in physics.

This book aims to unravel some of the mysteries surrounding this exceptional group of larger-than-life Bronze Age blades.

This book is witness to Hendrik Vanden Abeele’s research into the development, construction and creation of a present-day performance practice of late medieval plainchant, based partly on his work with the Belgian chant group Psallentes.

On Thursday 16 November, Dirk Broekhuijsen defended his doctoral thesis entitled ‘A multilateral tax treaty: designing an instrument to modernise international tax law’. The supervisors are Professor F.A. Engelen and Professor S.C.W. Douma.

Promotores: Prof.dr. D. Bouwmeester, Prof.dr. A. Fiore (TU Eindhoven)

This thesis consists of two subjects, that are both a consequence of radiation pressure.

In this thesis, time-lapse fluorescent microscopy plays a pivotal role in investigating functional materials within living cells as well as the migratory behaviour of neural progenitor cells.

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.

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.

The profile area Political Legitimacy brings together researchers from multiple research institutes within Leiden University.

In late medieval and early modern times, books, as well as the people who produced and read (or listened to) them, moved between regions, social circles, and languages with relative ease. Yet, in the multilingual Low Countries, francophone literature was both internationally mobile and firmly rooted…

We use DNA strands to stabilize few-atom silver clusters, which show unique optical and chemical properties. This thesis involves the study of these constructs for various applications.

We investigate how radiation pressure can be used to influence the mechanical motion of a micro-mirror suspended from springs.

A plasma is an ionized gas with very low electrical resistivity. As such, magnetic field lines are 'frozen in' and move with the fluid. Magnetic field lines that are linked, knotted and tangled, cannot be undone by the fluid motions.

Of the 111 Spinoza Prizes that have been awarded since 1995, 28 have gone to researchers from Leiden University.
