Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

In this book, Vanessa Newby provides the first detailed examination of credibility’s essential place in peacekeeping.

The focus of Jan Zaanen's theoretical physics research was the nature of macroscopic matter that is in one or the other way still in the grip of quantum physics.

The focus of our theoretical research is understanding the behaviour of soft condensed matter, physical matter which is deformed or structurally altered by thermal fluctuations or small stresses.

As part of the Paris Agreement, countries across the world agreed to support developing countries to invest in climate mitigation and adaptation through a Green Climate Fund. However, developed countries have failed to meet funding commitments for the Green Climate Fund–the flagship program financing…

Of all the mass in our Universe, 80% is thought to consist of a hypothetical and invisible substance called dark matter (DM).

A Student Affairs Front Office employee will explain the main considerations for applying to Leiden University.

We investigate emergent structures and dynamics of soft materials self-assembled from microscopic constituents.

We are a dynamic research group at the Leiden Institute of Physics. Our aim is to explore and understand quantum materials, including strange metals, high-temperature superconductors, and quantum critical electron matter.

Get to know us through our online and in-person events for prospective students!

On Wednesday, 14 May 2025, Catherine O'Regan will deliver the annual Van Vollenhoven Lecture

On 25 January 2024 H.J. Pak successfully defended a doctoral thesis and graduated.

The main aim of this project is to reveal and unravel the invisible histories of the UN, transcending the dominant Western perspective to recover the historical agency of Global South actors. The research will investigate how the UN has both facilitated and limited their role in shaping global order…

The Physics and Biological and Soft Matter master's specialisation is one of the two programmes that Leiden University offers in experimental physics. This programme mainly focuses on Biological Physics and Soft Matters Physics.

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,…

This research deals with the royal houses of the Vijayanagara Empire and four of its successor states: Ikkeri, Tanjavur (under both the Nayaka and Bhonsle rulers), Madurai, and Ramnad. This study is thus concerned with dynastic politics and imperial legacies in south India between the 14th and 18th…

Nematic liquid crystals form the key ingredients of most tv screens. The active version of these complex fluids forms a useful model for physicists to research the responses of active matter—like bacteria or traffic flows—to mechanical and geometrical cues. An international research team publishes their…

Three major cosmology-focused missions are planned for the next decade: the Euclid space telescope, the Vera C. Rubin Observatory in Chile, and the Nancy Grace Roman Space Telescope.

The Laiseang archiving project ensures the preservation of unique records of languages in the region which have been gathered by more than two dozen linguists at, and in collaboration with Dutch universities over the last 40 years.

The archaeological heritage of South America is facing increasing threats due to the expansion of agricultural activities, infrastructure expansion, illegal wood harvesting, and the current fire emergency plaguing the Amazon and other biomes of the continent.

Researchers using remote sensing technologies have characterized pre-Columbian regularly-shaped earthworks in forests in Central America and the Amazon. In tropical forested mountains in South America, two challenges arise when identifying archaeological sites through remote sensing. Firstly, sites…

This project, South American population history revisited: multidisciplinary perspectives on the Upper Amazon (SAPPHIRE), investigates population dynamics in western South America on the basis of traces in the geographical, genetic, archaeological, ethnological, and linguistic record.

Early Childhood Community Practitioners’ analyses of new mother’s challenges in Alexandra Township South Africa: a collaboration between academics and practitioners

Escalating tensions in South China Sea have epitomized US–China relations for nearly a decade. Warning signs of a possible collision between a rising China and steadfast US, bring to light the need to think about ways that can halt and reverse the intensification of their confrontational moves.

LCCP has a research seminar that meets once a month. It is devoted to discussion of work in progress, but it also hosts guest speakers from other universities presenting their current or ongoing work.

Because thin systems can deform along the thickness with relative ease, the interplay between surface mechanics and geometry plays a fundamental role in sculpting their three-dimensional shape.

The CSPPR’s activities range from hosting public events to small-scale seminars with internal and external experts.

The CEES Centre regularly hosts (guest) lectures, roundtables, and film screenings.

At Leiden University College (LUC), engagement with international societal partners occurs through research, education, and internships, fostering mutually beneficial collaborations with NGOs, public service institutions, and international counterparts.

Subproject of the ERC project 'Challenging the Liberal World Order from Within: The Invisible History of the United Nations and the Global South'.

Research in the Daniela Kraft Lab focuses on self-assembly in biological and soft matter systems, ranging from anisotropic colloidal particles to lipid membranes, emulsions, and viruses.

The aim of this research is to define the relationship between sources of articulation for different kinds of instrument in the period between the beginning of XVI century (first extant indications) and the end of XVIII century.
