This proposal aims at the construction of a comprehensive and authoritative scientific grammar for Dutch and Frisian in the form of a virtual language institute: het Taalportaal/the Language Portal.

This dissertation investigates whether and how gradability is manifested in the nominal domain, as well as the implications this could have for theories of the representation of gradability.

Maartje van der Woude, together with Dr Irene Vega, has won the 2024 Theoretical Criminology Best Article Prize for the article ‘Colourblindness across borders: The de-racialised logics of Dutch and American border agents’ in the journal Theoretical Criminology.

In welke mate hebben domaniale structuren de machtsvorming en nederzettingsontwikkeling in en van het gewest Holland bepaald?

Tim Koopmans is one of the great minds in the history of Dutch and European legal scholarship. He taught law as a professor in Leiden and other universities, among which Ghent, Cambridge, Utrecht. He practiced it as a judge in the European Court of Justice and Advocate-General in the Dutch Supreme Court,…

The aim of this project is to study the influence of Longinus’s treatise ‘On the sublime’ on practice and theory of architecture and theatre in seventeenth-century Paris and Amsterdam.

A ‘new governance culture’ – a hot topic for a number of years now. What kind of culture of public administration do we have in the Netherlands and how do you change it? This question is the focus of the podcast Het Spel & De Macht (the Game & the Power). Each episode considers one theme related to…

The theoretical explanation of cosmic acceleration is nowadays one of the biggest puzzles in cosmology.

During my PhD research, I studied the photon statistics of light emitted by a microcavity that contains a single quantum dot (QD) on resonance.

Video interview with Subodh Patil, the new assistant professor in Theoretical Cosmology, about the gravitational waves, hidden universes, music, and whether Dutch, Danish and German fit into one brain.

Does gravity work the same when you look at the largest scales in our universe? That’s what Leiden physicist Alessandra Silvestri will study with a 2 million euro ERC Consolidator grant. ‘We assume that it does, but we don’t actually know.’

The probability for dissociation of molecules on metal surfaces, which often controls the rate of industrially important catalytic processes, can depend strongly on how energy is partitioned in the incident molecule. There are many example systems where the addition of vibrational energy promotes reaction…

This thesis contributes to studying primordial cosmology theories and their detectability in future observations.

The Theoretical Philosophy programme consists of 60 EC, to be completed in one year.

Catalysis is of extreme relevance in the production of everyday materials and plays a central role in many aspects of our life.

The Theoretical Physics specialisation prepares you for a career in industrial research and performing problem solving tasks. The master degree is an excellent stepping stone for pursuing a PhD degree.

The work in this thesis demonstrates how to obtain an atomic-scale picture of a diverse set of complex surface structures observed using STM, under disparate conditions.

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.

During the programme you will develop strong analytical and computational skills.

The dissociative chemisorption of methane on metal surfaces is of fundamental and practical interest, being a rate-limiting step in the steam reforming process. The reaction is best modeled with quantum dynamics calculations, but these are currently not guaranteed to produce accurate results because…

Nonadiabatic energy transfer from the translational motion (T) of a molecule impinging on metal surface to the metal’s electrons may determine whether the molecule can lose enough energy to adsorb or react.

Several techniques are explored for going beyond the born-oppenheimer static surface model for molecule-surface reactions.

On 3 December 2020 (at 14.30) Janna Everaert will defend her dissertation "Macht in de metropool. Politieke elitevorming tijdens de demografische en economische bloeifase van Antwerpen (ca. 1400-1550)". To attend this event please send an email to janna.everaert@vub.be.

The master’s specialisation Cosmology at Leiden University is positioned at the interface between Theoretical Physics and Observational Astronomy. The main elements are theory, data analysis and numerical simulations, with research on the origin of dark matter as one of the highlights.

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.
