The master’s specialisation Physics and Science Based Business at Leiden University bridges science and business development by focusing on areas such as technology management, innovation, entrepeneurship, operations, and decision making.

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.

The central inquiry of this thesis revolves around how ontology can adequately accommodate the existence of necessary physical relations. Initially, the thesis demonstrates the imperative acknowledgment of necessary physical relations by showcasing the failure of Neo-Humean theories.

This research examines the social, political, and cultural forces that structure people’s responses towards accented speech, and further uses the accent as a focal point to theorize the interrelation between language and body.

In this thesis, we examine various systems through the lens of several numerical methods.

Persistent somatic symptoms are long term symptoms that lack a clear medical explanation. These symptoms have a high prevalence where most people know someone who experiences such symptoms or they experience such symptoms themselves. Symptoms can vary greatly in and between people. While one person…

Why do sexual violence policies still fail to systematically address men and masculinities, when the need for cultural change among men has been central in public debates since #MeToo?

In this article, Marieke Liem and Kim Moeller revisit Goldstein’s framework on the drugs-violence nexus

Jasmina Mačkić, Assistant Professor of Human Rights Law at the Europa Institute, has published her book, Proving Discriminatory Violence at the European Court of Human Rights. This work is based on her doctoral dissertation, which she defended in May 2017 and which was funded by the Netherlands Organisation…

Grace Leksana defended her thesis on 26 May 2020.

On 17 August 1945, two days after the Japanese surrender that also brought an end to the Second World War in Asia, Indonesia declared its independence. The declaration was not recognized by the Netherlands, which resorted to force in its attempt to take control of the inevitable process of decolonization.…

The master’s specialisation Physics and Science Communication and Society at Leiden University bridges the gap between experts and the public by combining high quality research in biology with extensive training in science communication.

Research reveals how boys respond to harassment awareness training and why they often fail to see street harassment as 'their' problem.

This master’s programme combines Physics with Data Science. You will learn how physics has its own tricks to deal with big data and how techniques from machine learning and deep learning can be applied to classical and quantum data. The first focus of attention is on classical data, including data mining,…

This paper contributes on an increasing body of work on radicalisation. It specifically focuses on what distinguishes individuals whose behavioural radicalisation includes involvement in terrorist violence from those whose behavioural radicalisation does not.

This interdisciplinary study focuses on (trans)national ethnic and popular networks, combining historical-ethnographic and computational methods to understand the ‘workings’ of networked conflict interfering in the increasingly violent conflict in the Sahel (Africa) and beyond. The project focuses on…

This is the physics summer school of Leiden University. It is part of the Leiden Institute of Physics (LION). The summer school is intended for Bachelor (BSc) students in physics. It covers topics from quantum matter and optics, to biological & soft matter physics and cosmology and theoretical physics.…

My work is motivated by the necessity to extend Standard Model of Particle Physics in order to explain three observed phenomena that this great theory fails to accommodate

Promoting sustained physical activity through tailored incentive-based interventions for diverse cardiovascular disease patient groups.

Practical information about the physics summer school of Leiden University: the frontiers of modern physics. This page contains information about the cost and price of the summer school, the available scholarships, location, housing and the programme. This summer school is a part of the Leiden Insitute…

How have British, Dutch, and German security services dealt with political violence and terrorism since the late 1960s; to what extent did they consider these new phenomena as a task and how have they developed activities in order to counter these security threats?

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

The Tatiana Afanassjewa-lecture series is a series of public talks in Dutch by Leiden physicists on wednesday evenings, intended for everyone with an interest in physics.

Shape and biological function are tightly connected. Physical descriptions are used to connect the shape of a biological system with its function.

The Dutch and English East India Companies were formidable organizations that were gifted with expansive powers that allowed them to conduct diplomacy, wage war and seize territorial possessions. But they did not move into an empty arena in which they were free to deploy these powers without resista…

Violence during war often involves upswings and downturns that have, to date, been insufficiently explained. Why does violence at a particular point in time increase in intensity and why do actors in war decrease the level of violence at other points? Duyvesteyn discusses the potential explanatory variables…

A new paperback edition of Brian Heffernan's book Freedom and the Fifth Commandment. Catholic priests and political violence in Ireland, 1919-21 was published by Manchester University Press in September 2016.

The largest structures in the Universe are clusters of galaxies. Each can contain hundreds to thousands of galaxies.

Policy Note Insecurity in Burkina Faso – beyond conflict minerals: The complex links between artisanal gold mining and violence

Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

The Standard Model (SM) of particle physics fails to explain several observed phenomena and is incomplete. In order to resolve this problem, one may extend the SM by adding new particles.

This research revolves around the philosophical and linguistic elements that naturally belong to the process of learning music scores, including complex contemporary repertoire distinguished by physically decoupled notations or physical polyphonic notations.

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.

The master’s specialisation Research in Physics, Quantum Matter and Optics at Leiden University offers a thorough experience on the front line of physics research with a practical training of communicative and computer skills. The programme focuses on Condensed Matter problems, such as Molecular Electronics,…

In the academic year 2021-2022 the Social Resilience and Security interdisciplinary programme will offer two courses for interested students who are entering the third year of their Bachelor's degree. You can sign up for these courses in your elective (minor) space. The courses are available to students…

Systems with local constraints is a new finding in recent researches on complex systems. The heterogeneous spatial interactions and the temporal dependencies among those numerous units make it difficult to describe by traditional statistical physics.

The out of control ‘Project X’ event in Haren, hooligans who arrange to meet up to fight and beach riots at the Hoek van Holland: group violence is increasingly hitting the headlines.
