The powerful Dutch East India Company and West India Company were summoned before the High Court more often than historians have assumed. The complainants varied from competitors, to the Companies' own staff and even poor citizens. This is what Leiden historian Kate Ekama has discovered. PhD defence…

To strenghten ties with the public, press, other academics and wider society, LION employs an outreach officer.

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.

During the bachelor’s programme Astronomy you will immerse yourself in questions about our universe. Questions such as: ‘what happens in a black hole?’ and ‘what is dark matter?’ In doing so you will learn to apply mathematics and physics to astronomical problems and you will work with computer simulations…

The Tatiana Afanassjewa-lecture series was a series of public talks in Dutch that was started during the Covid-19 lockdown. The talks were given by Leiden physicists on wednesday evenings, intended for everyone with an interest in physics.

The High-Tech Innovation specialisation consists of a 60 EC track alongside the students' core MSc programme: Astronomy, Chemistry, Computer Science, Mathematics and Physics.

This thesis aims to demonstrate how the achromatic nature and design flexibility of liquid-crystal optics can be used to improve high-contrast imaging instruments to facilitate detailed exoplanet characterization.

The Astronomy and Instrumentation specialisation consists of 120 European Credit Transfer System (EC) points and includes highly specialized instrumentation courses, a selection of advanced electives and two research projects.

In this first ever podcast from LUCIS, hosts Yasmin Ismail & Sara Bolghiran explore what it means to imagine Muslim futures. Over 6 episodes we explore questions around what it means to imagine, the politics of imagination and what it would mean to engage with Muslims from the perspective of futures…

Inspired by natural photosynthesis, perovskite-based photoelectrochemical (PEC) systems are being developed for artificial photosynthesis, aiming to enhance solar-to-hydrogen conversion for green energy.

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars, which are called exo-planets. They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems.…

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.

Researchers at Leiden Observatory study the fundamental physics that creates structure in the Universe. These processes collect matter into galaxies and gas into stars. With the use of powerful telescopes and advanced calculations and computer simulations, Leiden astronomers seek to understand the origin,…

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 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.

Within the two-year Astronomy master’s programme, you can choose from seven specialisations, ranging from fundamental or applied astronomy research in cosmology, instrumentation or data science, to combinations of astronomy research with education, management or science communication.
