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 master’s specialisation Research in Theoretical Physics prepares you for a PhD position in theoretical physics. The research entails a broad range of topics including High Energy Physics and Particle Cosmology, Theoretical Physics of Life Processes and Condensed Matter Theory.

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.

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…

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…

Veel mensen denken dat zware metalen giftig zijn en mens en natuur altijd schade aanbrengen. Dat beeld moet genuanceerd worden, vindt hoogleraar Sylvestre Bonnet.

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.

Inaugural lecture

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…

Het zal niemand ontgaan zijn dat de digitale dreigingen blijven toenemen. Uit monitoring door onze cybersecurity-experts blijkt dat er continu wordt geprobeerd om ook onze systemen binnen te dringen. Wat doen wij daartegen en hoe kan jij als medewerker bijdragen aan onze cyberveiligheid?

Stilzitten doet alumnus Bart Jansen niet graag. Zo geeft hij les in onder meer Nederland, Maleisië en Curaçao, houdt hij zich naast het recht ook graag bezig met kunst en mystiek en vindt hij naar eigen zeggen ‘alles wat fout gaat’ wel interessant aan de rechtsfilosofie. ‘Ik ben gek op veelzijdige mensen;…

Do you often feel drained after a day at the office? The new SPS Monitor measures how sensitive you are to various stimuli. Psychologist Véronique de Gucht developed the questionnaire. 'I want to demystify high sensitivity.'
