What issues arise in the changing landscape of privacy, identity and data protection?

Leiden scientists and companies receive 1.37 million euros to develop technology for the Einstein Telescope. This underground telescope will measure gravitational waves and must therefore be extremely sensitive. To that end, the consortium conducts research on the damping of vibrations at temperatures…

Many important topics in computer science, such as the correctness of software, the efficiency of algorithms and the modeling of complicated systems, depend on sound theoretical underpinnings. In the Theory group, we study these fundamental building blocks and develop verification methods to prove system…

Leiden students often prefer complicated theory and a difficult test to experiments. Yet associate professor Paul Logman believes students learn a lot from practical teaching. He challenges his students to come up with their research questions themselves. The Leiden Institute of Physics (LION) is at…

Our world is shrinking, or at least our electronic devices are. From PCs to mobile phones: everything is smaller and thinner. The smaller the chip, the better it can conduct electricity and pass on information.

Last Thursday the Dutch House of Representatives held a debate on children being put into care when the childcare benefits scandal (toeslagenaffaire) had caused problems for their families. Four Leiden University academics were asked by the House to produce a fact sheet for this debate, bringing together…

Within the field of astronomy, understanding how galaxies grow and evolve from the Big Bang to the present day is a challenging and complex question.

Astronomical observations of cold regions in the universe show a rich inventory of ices. Part of these ices may end up on planets like our own, but in that journey they will be exposed to considerable amounts of radiation.

His Leiden honorary doctorate, the future of scientists, and diversity in science. Robbert Dijkgraaf tells about it in one of the classical rooms of the Academy Building. ‘It's very special, my honorary doctorate. A rare homage.’

NWO has assigned Physics Vrije Programma grants to five collaborations of physicists. Leiden University is involved in three of them.

Lecture

Your time at Leiden is about more than just studying. Some of your best experiences will stem from being a part of our lively and diverse student community, as well as from life in the beautiful city of Leiden.

Advanced sensing techniques require graphene with high quality and well-controlled surface chemistry.

An all-optical transistor, a molecule-sized sensor and a new kind of single-photon source for quantum communication. All dreamed applications of fundamental physics that are one step closer thanks to Robert Smit. On 12 June, he defended his PhD thesis with distinction.

Making the most vibration-free, cryogenic scanning tunneling microscope in the world. A bold mission, but one that PhD candidate Irene Battisti successfully executed together with the Fine Mechanical Department. The new microscope might shed light on how unconventional superconductivity works. PhD Defence…

Worldwide resurgence of pertussis necessitates the need for improvement of pertussis vaccines and vaccination strategies.

In this study the central question to be answered is whether children are able to participate in decisions and at which moments these decisions are taken in the youth care trajectory.

Despite the rain and awful weather, the painting job has been finished within a week. The Van der Waals-state equation is the eighth Leiden wall formula.

In opdracht van het WODC doen onderzoekers van de Universiteit Leiden onderzoek naar de landelijke daling van het aantal jeugdbeschermingsmaatregelen en jeugdreclasseringstrajecten. Bij dit interdisciplinaire onderzoek zijn onderzoekers van de afdelingen Jeugdrecht en Gezondheidsrecht, Bedrijfswetenschappen…

Dr. Kirsten Leiss and Prof. Peter Klinkhamer received 900.000 euro’s from “Stichting Toegepaste Wetenschappen (STW)” and the company “Rijk Zwaan” to develop plants that are resistant to thrips, a major agricultural pest all over the world.

String theory has come under fire in recent years. Promises have been made that have not been lived up to. Leiden theoretical physicists have now for the first time used string theory to describe a physical phenomenon. Their discovery has been reported this week in 'Science'.

The 2018 Physics Nobel Prize is awarded to Arthur Ashkin, Donna Strickland and Gérard Mourou for their research on optical tweezers based on lasers. Leiden physicists comment in the following media.

Taner Kuru, an eLaw alumnus, was awarded the prestigious European Data Protection Law Review ‘Young Scholar Award’ for his paper on the shortcomings in the GDPR for the regulation of genetic testing at the prestigious Computers, Privacy and Data Protection Conference (CPDP).

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.

The programme guarantees a thorough experience on the frontlines of physics research AND data science. It focuses on research areas where these fields overlap and in the process provides practical training of communicative and computer skills.

Many important topics in computer science, such as the correctness of software, the efficiency of algorithms and the modeling of complicated systems, depend on sound theoretical underpinnings. In the Theory group, we study these fundamental building blocks and develop verification methods to prove system…

Louk Rademaker is visiting fellow at Leiden University, Lorentz Institute for Theoretical Physics. He studies theoretical quantum matter physics, connecting the material science to fundamental concepts and methods.

Jan Zaanen, Professor in Theoretical Physics of condensed material, has been awarded a Spinoza prize. His pioneering ideas about the collective behaviour of quantum particles and high temperature superconductivity have often given him the reputation of being something of a rebel.

The Leiden Institute of Physics (LION) is the coordinating partner in the Qluster research project, which was awarded a 2,9 million euro FET Open grant by the European Union. The three-year project, which started on 1 December 2019, aims to produce many photon entanglement to aid quantum communication…

On 22 June the International Centre for Migration Policy Development (ICMPD) organised a webinar on the challenges that have arisen for asylum seekers and refugees worldwide as a result of the COVID-19 crisis.

Corinne Dettmeijer-Vermeulen, the well-known legal expert and Leiden University alumna, was for many years the National Rapporteur on Trafficking in Human Beings and Sexual Violence against Children. On 26 November she will deliver the Cleveringa lecture.

As of 1 June, Leiden University has appointed Sense Jan van der Molen as Professor Physics of Condensed matter. He investigates the unique electronic properties that arise when atomic thin layers are stacked on top of each other into new materials.

Animal species that are dear to us in the Netherlands often spend a large part or all of their lifecycle in other parts of the world. But their habitats worldwide are under increasing pressure, are often inadequately protected and much poorer than the global average. ‘If we truly care about these animals,…

In mid-March 2020, the European Commission adopted, against the background of the Corona pandemic, temporal common rules for the export into third countries of personal protective equipment, needed in the context of the Corona pandemic, out of the EU.
