On the 28th of September Go Hirasawa successfully defended a doctoral thesis and graduated.

This thesis consists of two subjects, that are both a consequence of radiation pressure.

n this thesis we study curves. In the first half, we study moduli spaces of curves and Gromov-Witten invariants, certain kinds of curves counts. We employ logarithmic geometry for this.

Biological polymers, including proteins and the genome, undergo folding processes crucial for their proper functioning. Even slight changes in the folding structure of these biopolymers can have significant implications, leading to the development of various pathological conditions, such as neurodegenerative…

Mechanical interactions between cells and their environment play an important role in many biological processes.

The first direct detection of gravitational waves opened the possibility of mapping the Universe via this new and independent messenger.

The focus of the Multicriteria Optimization and Decision Analysis (MODA) group is to develop foundations of methods in multi-objective optimization.

The Platform for Postcolonial Readings brings together researchers, especially junior researchers, in Belgium and the Netherlands interested in issues of globalization, inter/transculturality, diversity and inclusivity, intersectionality, and postcoloniality. We are an open group (do join us!) and meet…

This research profile area brings together descriptive, historical and theoretical linguistics, as well as psycho- and neurolinguistics.

The overarching aim of the ICLON research programme is to improve the quality of teaching-learning situations through a deep theoretical understanding of teaching and teacher learning.

In unconventional high temperature superconductors, supercurrent vortices are known to spoil the Landau levels. In this thesis the emergence of Landau levels is studied in different types of superconductors: Weyl superconductors, and the Fu-Kane heterostructure.

While it has traditionally been seen as a means of documenting an external reality or expressing an internal feeling, photography is now capable of actualizing never-existed pasts and never-lived experiences.

Research in the natural computing group covers theoretical foundations, the development of new algorithms, and interdisciplinary applications of natural computing methods.

You have ample opportunities to assemble your own study path. The courses cover the full spectrum from theoretical early universe to observational cosmology.

The Regular LL.M. (specialization in Public International Law) will provide you with a broad academic training.

In this thesis, we have used numerical approaches to study the effects of translational symmetry breaking on strange metallic systems as realised by the holographic duality⁠.

On the brink of war, what influences decision makers to attack another country? Using innovative theoretical angles, Femke E. Bakker explores whether the basic assumptions of democratic peace theory are indeed correct. She stresses the microfoundations of conflict, questioning the assumptions on…

The SCS courses train you in practical and theoretical aspects of science communications. Internships help you decide whether you want to choose a career in science communication or Computer Science.

This thesis discusses the discovery potential of Intensity Frontier experiments.

In this dissertation I argue that the proto-daoist text the Zhuangzi and the ethical relation of Levinas are fruitful resources to reconsider the self-other relation in comparative philosophy.

Alex Colling himself calls his bachelor's thesis ‘the highlight of his time in Leiden’. And according to his supervisors, that resulted in an outstanding thesis, with great attention to detail. The Mathematics and Physics student worked on a mathematical description of monopoles: hypothetical particles…

Predicting the collective behaviour of systems, like a large group of people electing one of the parties, is no easy task. But there’s a theory that scientists have been using for decades to do just that: the theory of Gibbs measures. Last week, mathematician Mirmukhsin Makhmudov earned his PhD for…

Swarms of drones, pedestrians or the cells in your body. Those are all examples of active matter: materials whose building blocks can move autonomously. That’s what Luca Giomi studies. Giomi has been appointed Professor of theoretical physics in the area of soft matter and biological physics at the…

Explore the research of the Institute for Philosophy, organised into five centres that connect historical and systematic approaches to ethics, logic, and the history of ideas.

The master’s programme Physics at Leiden University offers a wide range of specialisations from theoretical research to cosmology. You will be trained for a career in research or for a more practical-oriented specialisation. The programme offers a wide choice of individual study paths that take into…

With a MSc in LST you are well prepared for a wide range of career opportunities. Life Science research and business is one of the fastest growing economic activities worldwide.

In the specialisation Clinical Neuropsychology, part of the Master in Psychology, you will focus on fostering clinical and scientific skills based on a solid theoretical background as well as practical training in neuropsychology and (clinical) neuropsychological research.

If X is a locally compact Hausdorff space, then a representation of the complex C* algebra C_0(X) on a Hilbert space $H$ is given by a spectral measure that takes its values in the orthogonal projections on $H$.

In this research note, Van der Does & Kantorowicz aruge that citizens that tend to experience political exclusion are often more supportive of direct and participatory forms of decision-making.

Receiving a gift is nice, but giving a present also makes you happy. Development psychologist Mara van der Meulen former member of the Leiden Consortium on Individual Development (L-CID) answered four questions about giving gifts.

The central goal of academic publishers is the dissemination of the results of research and scholarship. Their audiences can generally be divided into two categories. Academic publications are firstly made accessible to the scholarly community, so that these texts can form the input for new academic…

We are cosmologists, in other words we use physics to study the Universe, how it started and evolved into the structure that we observe around us.

Explore the programme of the MSc Political Theory: Legitimacy and Justice at Leiden University — focusing on core political philosophy themes, in-depth theory, methods, elective seminars, and a thesis or internship track.

With a lot of theoretical knowledge, practical experience, and your bachelor's degree in the pocket, you are ready for the next step: either entering the archaeological job market or continuing your studies.

Hegemony and World Order explores a key question for our tumultuous times of multiple global crises.

Between 1600 and 1800 countless manuals appeared on the subject: the improvised bass part on the harpsichord, pianoforte or organ. Musician and researcher Kathryn Cok unravels the secrets of the Dutch basso continuo accompaniment for modern-day musicians.

This project aims to systematically investigate the influence of information structure on nominal licensing in a subset of Bantu languages.

This work represents the final results of several years of research within the Maya region. It deals with the relations between architecture and urbanism with landscape and astronomy.

What are the conditions under which coercive diplomacy can compel a State to abandon its nuclear weapons program?

Research at the Leiden Institute of Physics (LION) is foundational and curiosity driven. All our scientists share a desire to increase the knowledge of the world around us, in an open atmosphere of inquiry from which innovative ideas emerge that provide applications and value for society.

The main aim of this project is to investigate the various ways in which language categorizes possession, how these are morphosyntactically encoded across and within languages, and how this distinction should be represented in a model of the language faculty.

The one-year master’s in Linguistics is concerned with the knowledge, structure and use of language, studied from a wide range of perspectives. It trains students to systematically identify, describe and analyse language phenomena and to apply this knowledge to a specific area of interest.
