Hoe kan de City Deal Kennis Maken bijdragen aan het formuleren van maatschappelijk relevant onderzoek dat de stad in al haar diversiteit centraal stelt? In de stad Leiden zijn burgers momenteel maar in beperkte mate betrokken bij het bepalen van de agenda van de lokale City Deal Kennis Maken. Dit onderzoeksproject…

In the spirit of 'unity in diversity', our objective is to promote insight into and appreciation for the wonder that the same physical laws and mathematical concepts apply to the whole of nature, from the largest to the smallest energy and length scales. We strive for the application of abstract theoretical…

Leiden has a strong tradition in theoretical physics, thoroughly linked with experimental disciplines.

Theoretical linguistics seeks to understand the underlying principles of the nature of human language.

Studying the underlying principles of the nature of language.

The main goal of the THEOR CHEM group, headed by Prof. Geert-Jan Kroes, is to characterize, and to accurately predict the outcome of chemical reactions at gas-solid and liquid-solid interfaces. Here the solid surface is typically a metal or an ice surface. These goals are important to many areas in…

The Leiden Centre for Theoretical Philosophy (LCTP) is a platform for analytic philosophy in a broad sense at Leiden University. Its members do research in philosophy of science, philosophy of logic and metaphysics, with a keen interest in the history of topics such as mind, knowledge, truth, and ti…

The research programme Formal Theoretical and Experimental Linguistics brings together LUCL researchers who focus mainly on formal theoretical and experimental linguistics.

Describing a new language for the first time is an exciting and challenging intellectual experience.

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.

On 11 October, the roundtable entitled ‘Academic Freedom – Theoretical Perspectives’ took place at Leiden University's Academy Building. This event was organised as part of the Vidi research project entitled 'The EU fundamental right to 'freedom of the art and sciences': exploring the limits on the…

The group Theoretical Physics of Life Processes, led by Helmut Schiessel, focuses on the physics of chromatin, the DNA-protein complex that fills the nuclei of eukaryotic cells.

This book brings together a collection of emergent research that moves the debate on desistance beyond a general consideration of individual and social structural influences.

Audiovisual and Digital Ethnography is a state-of-the-art introduction to this dynamic and growing subject. The authors explain its fundamental aspects in a clear and systematic way.

This dissertation presents new cryptographic protocols, which can be divided into two families.

This dissertation provides an account of polar questions in Italian dialects from a typological, theoretical and empirical perspective.

In ‘Dimensions of Free Speech’, Devrim Kabasakal Badamchi (Leiden University Institute of Political Science) offers a new theoretical framework for free speech by critically analysing the major justifications for free speech. Kabasakal Badamchi argues for a justification: namely the double-grounded…

This thesis aims at contributing to our understanding of the semantic and prosodic properties of object foci in Greek, employing theoretical and experimental tools.

With the recent rise and fall of IS, academics and policy makers around the world are expressing concerns about the fate of children of former foreign fighters. Will they follow in their parents’ footsteps? In this paper, Layla van Wieringen, Daan Weggemans and Marieke Liem argue that in light of this…

Behrouz Karoubi defended his thesis on 15 June 2016

This research project focuses on the extended documentation and investigation of these non-Austronesian (‘Papuan’) languages.

De Code voor Kinderrechten op het internet toont makers van apps en games hoe zij de rechten van kinderen kunnen beschermen en meenemen in hun ontwerp. Dat is hard nodig, zeggen de opstellers hoogleraar Recht en Digitale Technologie Simone van der Hof en onderzoeksdirecteur Sander van der Waal van stichting…

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…

Waarom laaien er rellen op in het Verenigd Koninkrijk, aangespoord door de extreemrechtse British Defence League? Jorieke Manenschijn sprak met EenVandaag over hoe de beloftes van Brexit aan de woede hebben bijgedragen.

The Institute for Philosophy is pleased to host the OZSW Graduate Conference in Theoretical Philosophy on 9 and 10 January 2019

Professor Carlo Beenakker has been awarded a FOM Projectruimte subsidy to build a theoretical model of a majorana gun, a very promising instrument for quantum computers.

It is theoretically possible that habitable planets exist around pulsars, rotating neutron stars. Such planets must have an enormous atmosphere that convert the deadly X-rays and high energy particles of the pulsar into heat. That is stated in a scientific paper by astronomers Alessandro Patruno and…

This volume offers a multidisciplinary view of cutting-edge research on bilingualism in Spanish and Portuguese-speaking regions, with the aim of building a bridge between sub-fields and approaches that often find themselves isolated from one another.

Wim van Saarloos will become vice president of the Royal Netherlands Academy of Arts and Sciences (KNAW), and return to the Leiden Institute of Physics as professor of theoretical physics. Currently, Van Saarloos is Transition Director at the Netherlands Organisation for Scientific Research (NWO).

Since February 1st, 2017 Célia Fonseca Guerra is appointed as professor at the LIC with a chair in applied theoretical chemistry. She will be a member of the Theoretical Chemistry group. Her research interests are related to bioinorganic chemistry and catalysis and her appointment at the LIC will strengthen…

The financial sector, supply chains and ecology. Not necessarily topics you might associate with physics, yet it’s exactly what new professor Diego Garlaschelli is dealing with. The common thread? Complex networks.

In this thesis we study the landscape of gravitational models which modify GR by introducing an additional scalar degree of freedom (d.o.f.) to source Cosmic Acceleration.

This dissertation provides a novel perspective on the interaction between quantifier scope and ellipsis. It presents a detailed investigation of the scopal interaction between English negative indefinites, modals, and quantified phrases in ellipsis. One of the crucial observations is that a negative…

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.

This study presents the first systematic investigation and detailed theoretical analysis of the temporal interpretations of sentences with bare (aspectually unmarked) predicates in Mandarin.

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.
