An overview of our infrastructure at the SPP division:

The first full-colour images of the cosmos from ESA's space telescope Euclid were presented today. Never before has a telescope been able to take such crystal-clear astronomical images of such a large part of the sky and so far into the deep universe. The five images illustrate Euclid's full potential;…

On October 14, the first symposium of the university-wide initiative SAILS took place. Scientists from Leiden University and other Dutch universities came together to share their enthusiasm and expertise in the field of Artificial Intelligence in a festive symposium, in the atmospheric Museum of Eth…

From 1 October onwards, Dennis Claessen and Marcel Schaaf will be the new directors of education of Biology. They will replace Han de Winde. Schaaf will be responsible for the bachelor, while Claessen will mainly focus on the master tracks of Biology. We gave students and the education office the change…

On September 12, Michel Orrit received his Spinoza prize in the Royal Theatre in The Hague from OCW Secretary of State Sander Dekker. With the award comes a budget of 2.5 million euro, to be spent freely on scientific research, and the coveted Spinoza statue. Orrit shared the honor with Eveline Crone…

Visualising cell proteins without invasive techniques is possible with the help of fluorescence. During a lecture of the Natuurwetenschappelijk Gezelschap Leiden on 18 January, winner of the Spinoza Prize 2017 and founder of the field of single molecule optics Michel Orrit explained how this works.

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.

The CIGR comprises research groups from the Institute of Biology Leiden (IBL), the Leiden Institute of Chemistry (LIC), the Leiden Academic Centre for Drug Research (LACDR) and the Leiden Institue of Physics (LION).

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

Michel Orrit was awarded the Physica prize 2016 for his groundbreaking work on single molecule spectroscopy.

From ransomware to Citrix traffic jams: over the past few months Dutch organisations were regularly brought to a standstill by serious cyber attacks. We can only face these threats by standing as one, and universities and government should take the lead. These are the words of Leiden professors Bibi…

Physics and Engineering Approaches to Biomedicine and Pharmacology

In the first part of this thesis we study the geometry of folding patterns.

This thesis mainly focuses on cross-modal retrieval and single-modal image retrieval via deep learning methods, i.e. by using deep convolutional neural networks.

In Quantum mechanics, particles can be in multiple positions simultaneously. Yet, when a measurement is made, the particle is found only in one place. Technology has come to a point where we may design experiments that will tell us how.

The local ordering of atoms at the surface of a metallic particle determines its catalytic activity and selectivity. As energy systems of the future will be based on efficient catalytic conversion of small molecules in closed cycles, we study how structural effects of catalysts can be used to our ad…

In this thesis I describe the results of Pulsed Interleaved Excitation and Fluorescence (Cross) Correlation Spectroscopy (PIE-F(C)CS) combined with single-pair Förster Resonance Energy Transfer (spFRET) used to study dynamics in single nucleosomes, which depends on subtle differences in the length of…

Why is there not just one single global law for cases of defamation in cross-border communication mediums such as the internet? Which courts are to be called on in such cases? And is it permissible to hold an intermediary instead of a content provider liable?

Gold nanoparticles show surprisingly strong interactions with light in the visible range, which can be divided into scattering, absorption, and photoluminescence.

We study the dynamics of individual emitters in micro cavities.

Research in the van Exter lab focuses on quantum aspects of light and light-matter interaction. One of our long-term goals is to develop a reliable quantum memory, based on a single emitter in an open micro cavity.

The stratum corneum (SC) plays a fundamental role in the barrier function of the skin. The SC consists of corneocytes embedded in a lipid matrix.

How is energy really dissipated on the atomic scale when sliding objects slip over a single lattice spacing?

Lecture

The Royal Netherlands Academy of Arts and Sciences (KNAW) selects prominent researchers as members based on their scientific achievements. On September 17th, the KNAW will install 21 new members, including Leiden physicist Michel Orrit.

The Catholics were by no means pitiable victims over the two centuries that they had to practise their religion underground, Caroline Lenarduzzi writes in her PhD dissertation. They managed to keep their faith alive from the mid-sixteenth to the mid-eighteenth century. PhD defence 25 October.

Niels Laurens recently started as the new Director of Operations at the Faculty of Archaeology as well as the Faculty of Governance and Global Affairs. We sat down with him for an interview on his background, his drive, and his take on archaeology. ‘My main drive is to enable researchers and lecturers…

Sense Jan van der Molen is vanaf 1 maart de nieuwe wetenschappelijk directeur van het Leiden Instituut voor Onderzoek in de Natuurkunde.

Mashaghi lab conducts research at the interface of physics, engineering and biomedicine. We develop and use theoretical and experimental approaches to address basic and applied research problems.

The Kroese-Duijsters Symposia aim to provide researchers from different fields and different career stages to meet in an informal setting, to stimulate discussions and to start new collaborations. The Kroese-Duijsters Symposia started in 2022 and we are pleased to invite you to the 3rd Kroese-Duijsters…
