Philosophy is about the Big Questions: do human beings have free will? Is capitalism a just system? Does science provide an objective picture of the world? At Leiden, you will investigate fundamental questions of this sort from a global perspective. Through careful examination of different philosophical…

'Today is the start of EL CID, the first of three introduction weeks at Leiden University. A new influx of students is ready and waiting, eager to get started. Vice-Rector Hester Bijl warmly welcomes all new first-years. ‘Go for it and grab your chances!’

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.'

Ten years after its introduction, the controversial idea of Erik Verlinde on gravity is still a hotly debated topic, and is still surrounded by a cloud of scepticism. Scepticism in which the media have played a major role, theoretical physicst Koenraad Schalm says in an article by NWO. ‘The media simply…

Almost a thousand students started HOPweek in The Hague on Monday morning. During this introduction week students get to know the city, the university and each other.

Lecture

The Dutch Research School for Theoretical Physics (DRSTP) has received excellent ratings from an independent international committee. The DRSTP is a school for PhD training which has grown out of a collaboration between the theoretical physics departments at six Dutch universities—including Leiden—and…

An overview of awards and prizes granted to our staff and students in 2018, as well as special appointments and royal distinctions.

We are delighted to announce that the Digital Humanities and Artificial Intelligence minor will be offered in the 2025-2026 academic year.

The two-years MSc programme spans the entire spectrum of Analytical BioSciences, Biopharmaceutics, Drug Delivery Technology, Medicinal Chemistry, Pharmacology and Toxicology.

The first book ever on information-theoretically secure multiparty computation

The colloquia Ehrenfestii take place about once every month. This lecture series has been running since 1912.

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…

A Josephson junction is a device where a thin insulating barrier or a nanostructure is placed between two superconducting leads. Such a junction is essential to superconducting qubits that store quantum information due to its anharmonic spectrum.

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.

Detecting nanoscopic objects plays an important role in nanoscience in particular, in the rapidly growing field of nanobiology. The forebear to modern super-resolution microscopy for single molecule investigation, is fluorescence microscopy.

Promotores: Prof.dr. M. Franx & Prof.dr. P.G. van Dokkum (Yale University)

Develop EPR instrumentation and methodology to investigate intrinsically disordered proteins (IDPs).

In this thesis, I study the formation of large-scale structure and the physics of particle acceleration at large scales (~Mpc).

On this page you can find the current vacancies at the Van der Molen research group.

Surface plasmons (SPs) are surface waves at the interface between a dielectric and a good metal, and are formed by the interaction between light and the free electrons at the metal-dielectric interface. They provide strong field confinement for optical fields, opening new possibilities for enhanced…

A dense region of a gaseous and dusty cloud collapses to form a protostar surrounded by a disk and an envelope. This thesis uses both observations and models to study physical and chemical conditions of these protostellar systems which are likely where planets start to form.

This PhD-research is conducted to test the hypothesis that Gutenberg and consorts developed a standardised and even unitised system for the production of textura type, and that this system was extrapolated for the production of roman type in Renaissance Italy.

Promotores: F.H. van Lunteren, F.P. Israel

In this thesis, bioorthogonal chemistry is combined with correlative light-electron microscopy to selectively label and study pathogenic intracellular bacteria within the host immune cell.

The CMCB brings together a diverse range of unique expertise in microbial cell biology. Members of the CMCB investigate both model and non-model organisms, bacteria and archaea, pathogens and non-pathogens.

In this thesis, we have studied the potential of the zebrafish larval model in studying the ECS, as a complementary model to the existing rodent models.

For each living organism health is ensured by correct functioning of its cells. Cells therefore have elaborate methods for regulation of their proteins.

The Nobel Prize in Physics 2016 goes to David Thouless, Michael Kosterlitz and Duncan Haldane for theoretical discoveries in the field of topological materials. Haldane spent part of 2008 in Leiden; he is the 14th Lorentz Professor to win a Nobel Prize.

Human cells are protecting their proteins from unfolding and aggregating. That's what biophysicist Alireza Mashaghi and his team discovered after seven years of in-depth research into the folding mechanisms of proteins. With an unprecedented approach, the team was able to study the folding of a single…

The Local Chamber of Associations (PKvV) has launched an online media platform that brings together all 24 Leiden student associations. It developed the platform over the past months in conjunction with Leiden University, University of Applied Sciences Leiden and Leiden Marketing.

This dissertation shows that dialogical logic constitutes a powerful and flexible general framework for the development and study of various logical formalisms and combinations thereof.

Yoshiyasu Yonezawa defended his thesis on 24 October 2019
