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.

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…

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.

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 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…

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…

How do cognitive, motivational, and affective processes interact to select actions?

This thesis examines the complexity of legislative decisions within the EU, with a specific focus on the Council of the EU.

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.

How to make educational innovations practical for teachers

How can the concept of Critical Making be expanded into a general approach that ties the critical methodology of artistic research, and the established concepts of artistic autonomy, together with contemporary creative-technological development?

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…
