The 2018 Physics Nobel Prize is awarded to Arthur Ashkin, Donna Strickland and Gérard Mourou for their research on optical tweezers based on lasers. Leiden physicists comment in the following media.

Human cells are protecting their proteins from unfolding and aggregating. That's what biophysicist Alireza Mashaghi and his team discovered after seven years of in-depth research into the folding mechanisms of proteins. With an unprecedented approach, the team was able to study the folding of a single…

The Leiden Institute of Physics (LION) is the coordinating partner in the Qluster research project, which was awarded a 2,9 million euro FET Open grant by the European Union. The three-year project, which started on 1 December 2019, aims to produce many photon entanglement to aid quantum communication…

Why did 'character', 'habit', and 'virtue' serve as key terms in late 19th and early 20th-century scholarly correspondences, biographies, and obituaries? Why did scholars around 1900 display so much interest in the working habits and character traits of what they called the 'scholarly self'?

Inaugural lecture

This doctoral project by artist and educator Luiz Zanotello engenders a postcolonial understanding of time, space and movement by means of artistic research methods. The project examines the contradictory effects of the abyssal line of thought within the tropics as a starting point.

Having encountered a series of shocks that pose an existential threat to our livelihoods, our societies have become increasingly polarized.

The Leiden Papyrological Institute is the only papyrological institute in the Netherlands. The members of our staff publish Greek (and Latin), Demotic (and Abnormal-Hieratic) and Coptic papyri from collections all over the world, including our own collection.

As of 1 June, Leiden University has appointed Sense Jan van der Molen as Professor Physics of Condensed matter. He investigates the unique electronic properties that arise when atomic thin layers are stacked on top of each other into new materials.

The Italian physicist Andrea Morello is one of the pioneers of the quantum revolution. He is currently doing research at the University of New South Wales in Sydney, but cherishes his time as a PhD candidate in Leiden.

The Leiden Lectures in Media | Art | Politics (MAP) is a series of talks organized by Pepita Hesselberth and Yasco Horsman. Speakers from various academic backgrounds and in different stages of their careers reflect on diverging ways in which technological and social changes challenge and transform…

The aim of this project is to study the influence of Longinus’s treatise ‘On the sublime’ on practice and theory of architecture and theatre in seventeenth-century Paris and Amsterdam.

The research profile area Interaction between Legal Systems has a multidisciplinary approach and aims to inspire innovative research. Out of all the proposals put forward, three winning projects have been selected for the forthcoming research period 2016-2020.

Physicists at Leiden University are developing smart chips that can be programmed with light. These chips are more energy-efficient than traditional chips because they do not require a constant power supply. For this research, they will receive funding in the coming years from the Dutch Research Council…

Alexander Kros studies supramolecular systems in a biological environment. The unifying theme between the projects in my lab is specific molecular recognition, i.e. the intermolecular interaction between complementary molecules with high affinity and selectivity. Studying, imitating and dissecting processes…

How does invasive hybridization affect threatened native species?

Do understudied animals contain hidden species?

Archaeological and related essays on the Jordan Valley in honour of Gerrit van der Kooij on the occasion of his sixty-fifth birthday

The major aim is to examine the potential of learning the body to produce a similar physiological (autonomic, neuroendocrine, or immune) and physical (e.g., desensitization of persistent physical symptoms) response to placebo medication than to active medication (pharmacological conditioning). If proven…

Knowledge of Muslim societies is essential to function in a globalised world and to fully understand our own Dutch society. Leiden researchers explore the languages, cultures, religions, legal systems and history of Muslim societies and in this way contribute to a centuries-old tradition.

How can reciprocal learning of mentor and mentee about PCK (Pedagogical Content Knowledge) during the secondary school internship be established?

The nanoscale structure of a catalyst under reaction conditions determines its activity, selectivity, and stability. For the production of sustainable energy and materials, new catalysts are needed. By understanding the structure-activity relationships of catalysts under reaction conditions, insight…

The Faculty of Science has multiple study associations, which organise both study-related and social activities for students.
