What is neutron star matter?

It is an established fact that the Standard Model has to be extended to explain the so-called Beyond the Standard Model (BSM) phenomena: dark matter, matter-antimatter asymmetry of the Universe and neutrino flavour oscillations.

In this thesis, the research focuses on the properties of dark matter and dark matter haloes and how they connect with the galaxies we can observe in the Universe.

Errors are everywhere, and mechanical failures are especially common: buckled grain silos and cracked support columns are, justly, seen as an issue to be avoided.

On 3 December 2019, Hanna Bosdriesz defended her thesis 'Furthering the fight against impunity in Latin America: the contributions of the Inter-American Court of Human Rights to domestic accountability processes'. The doctoral research was supervised by Prof. L.J. van den Herik and Prof. M.A.H. van…

On 1 September, the conference of the Kirchheiner Chair ‘Government and citizens: A matter of trust’ took place. In a packed hall in the beautiful Old Observatory of Leiden University, under the inspiring leadership of Willemien den Ouden, a debate was held on the role of the Dutch National Ombudsman,…

The ECtHR needs to provide effective rights protection, but it also needs to set clear standards while showing deference to decisions made at the national level. Especially when socio-economic issues are concerned, meeting these different demands is a challenging task.

Claire Vergerio, political scientist at Leiden University, has been awarded a VENI grant by Dutch research organisation NWO. This will allow her to conduct an in-depth analysis of the legal rights and duties of non-state actors involved in warfare. The aim is to tackle some persistent blindspots in…

The focus of our theoretical physics research is the nature of macroscopic matter that is in one or the other way still in the grip of quantum physics.

In the podcast series 'Open Geesten', historians Joost Welten and Nadia Bouras tell us about their research and how history is intergrated in modern society. In short: what can the past tell us about the present?

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.

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.

The humanities consist of various academic fields. But what is the common ground of all these different academics and students? And why does their work matter so much in today’s world? Watch the trailer of Humans of Humanties, the new documentary film about the Leiden Faculty of Humanities. Will you…

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

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

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.

What is the connection between materials with weak and strong gravitational interactions?

Ian Simpson is a relatively new face at the Faculty of Archaeology. Starting as an assistant professor in the Heritage and Society department in 2018, he is one of the faculty’s members in critical heritage studies and looks both at the past as well as the future. ‘I study how heritage can be employed…

For two years, Ineke Sluiter was president of the Royal Netherlands Academy of Arts and Sciences (KNAW). Now, she is returning to the university full time. ‘I always carry themes like accessibility, diversity and inclusion with me.’

The Laboratory for Human Osteoarchaeoloy examines human remains and their burial context to address questions about the human past.

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,…

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.

Since the end of May, the Faculty of Humanities 'Humanities Matter' art route has been on display. Due to the many positive responses, we have decided to postpone the end date of the exhibition from July 8 to August 28. So if you haven't walked the route yet, this is your chance!

Friday October 24th Honours students had to present their case studies on a topical issue related to Humanities. All Honours students made posters in pairs of two and had to defend their case in front of an audience at the Old Observatory. It was a tense experience, since they were being graded by…

An international team of astronomers has found an unexpected link between dark matter and visible stars in stellar systems. This discovery may even cause us to reconsider our understanding of gravity. They published on their discovery in 'Nature' on 1 October.

A hidden disability can make studying a considerable challenge, partly because of the disability itself, but also because others may not realise that extra support is justified. To overcome this problem, the Faculty of Humanities is introducing the Hidden Disabilities Sunflower.

Eduard Fosch-Villaronga, Hadassah Drukarch and Bart Custers from eLaw - Center for Law and Digital Technologies, explore together with Pranav Khanna, eLaw alumnus, the influence of automation on human–robot interaction and responsibility in surgery innovation.

Despite the field’s general agreement that pyrotechnology had a significant impact on the cultural evolution of humankind, our understanding of the origins and development of fire use and its role in humankind’s cultural evolution is very limited, blurred by strong disagreements over its chronology…

The currently available in vitro generated human skin equivalents resemble the human skin in many aspects. However, some essential barrier characteristics do not fully mimic the native barrier. Consequently, the human skin equivalents cannot be used for screening of drugs for skin penetration.
