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…

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

The master's programme in Theoretical Philosophy at Leiden University offers students the opportunity to investigate fundamental questions concerning the nature of reality using the tools of analytic philosophy.

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…

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

This dissertation focuses on the question how text and paratext contribute to the way that text in a network-like environment is clearly bordered and at the same time can easily be linked to other texts.

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.

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.

Reijer Passchier, universitair staatsrecht en hoogleraar digitalisering en de democratische rechtsstaat aan de OU, waarschuwt in HP/De Tijd hoe weinig controle we werkelijk hebben over kunstmatige intelligentie, terwijl machtige bedrijven steeds meer invloed krijgen op onze democratische samenleving…

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.

Reijer Passchier, universitair docent Staatsrecht en hoogleraar Digitalisering en de democratische rechtsstaat aan de OU, verzorgde op 20 maart jl. een actualiteitencollege over de macht van Big Tech, dat het Montesquieu Instituut, in samenwerking met de Academie voor de Rechtsstaat organiseerde.

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

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…

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

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

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

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…

Het Amerikaanse hooggerechtshof oordeelde op 1 juli dat een president tijdens hun ambtsperiode een zekere immuniteit heeft. Zij zijn onschendbaar in geval van ‘officiële handelingen’. Tessa van Buchem uit haar zorgen en kritiek in het FD.

The Nietzsche-Wörterbuch (NWB) has evolved into a long-term, multi-volume work on a global scale with around 30 contributors from a range of disciplines located all over the world

In this dissertation, we study partition-based models that can be used both for interpretable predictive modeling and for understanding data via interpretable patterns.

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…

Lecture

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.

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

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.

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…

Wordt het nog wat met de Arabische lente?

This study investigates the syntax and distribution of the two elliptical phenomena Gapping and Fragments, as well as the movements involved in ellipsis contexts in general.

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…

Politically speaking, the Frisian coastal area constitutes a special case in late medieval Europe since it was not subject to an overlord as it withstood feudalization in the 13th century. Its many sub regions, which were dominated by elites of small noblemen and freeholders, long time succeeded in…

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.

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…
