Truth is stranger than fiction. In 1997 Juan Maldaceña discovered a remarkable dictionary that translates equation for equation the physics of black holes in string theory into the more conventional physics of quantum mechanics of interacting particles. The remarkable possibility exists that…

Explore the MSc in Political Theory: Legitimacy and Justice at Leiden University. Dive into core themes like justice and legitimacy, study classical and modern political theory, and sharpen your analytical and philosophical skills.

This MA explores contemporary literature and culture—art, film, pop music—through critical and theoretical lenses, including feminist theory, phenomenology, and ecocriticism. Key themes include diversity, interculturality, popular culture, and the intersection of culture, politics, and justice.

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.

Imitation is, perhaps more than ever, constitutive of human originality.

My PhD research is devoted to studies of the conjectural cluster-algebraic symmetry in the theory of topological string, which is the simplest, however already non-trivial sector in the theory of string.

Conventional food supplies procured from rural areas are increasingly vulnerable to disruptions caused by extreme weather, geopolitical instability, and logistical bottlenecks.

‘A university is a slow-moving institution, which is in many ways a good thing,' commented student Josephine Rook at the opening of the Leiden University Green Office on 27 September in the Hortus botanicus. ‘Sustainability is not about following the latest trends, but about making structural improv…

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

This study looks at the question of how and at what level students in primary teacher education can integrate theory and practice, and how the organisation of their learning environment, focusing especially on mathematics and pedagogy, can contribute to that.

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.

Effective policy-making requires understanding what truly causes a problem. Only then can policymakers develop targeted interventions that achieve desired outcomes.

Humans can see the world through the eyes of other humans and imagine what they know, want, and intend. This competence is known as Theory of Mind.

The terms ‘social’ , ‘collective’ or ‘public’ memory, are often contrasted with ‘private’, ‘individual’ or ‘personal’ memory. All these terms derive from a fairly new and interdisciplinary scholarly field that is often referred to as ‘memory studies’, and that according to some critics has developed…

Systems with local constraints is a new finding in recent researches on complex systems. The heterogeneous spatial interactions and the temporal dependencies among those numerous units make it difficult to describe by traditional statistical physics.

In this work we describe three methods to improve the performance of Quantum Field Theory calculations.

Following their application to system biological models, control theory techniques have further potential to aid in the understanding and application of quantitative systems pharmacology models.

The next generation of high-contrast imaging instruments on space-based observatories requires sophisticated wavefront sensing and control in addition to a high-performance coronagraph.

On 16 april 2020, Andrew Fink defended his thesis 'The Importance of Conspiracy Theory in Extremist Ideology and Propaganda'. The doctoral research was supervised by Prof. A. Ellian.

The relevance of intentionality to the interpretation of Aristotle was first suggested by Brentano in his Psychology from an Empirical Standpoint. Here we take our starting point from Brentano and investigate how Brentano’s concept of intentionality is rooted in Aristotle.

Knowledge institutions play a unique role in society and can contribute to a future-proof and sustainable world. That’s why Leiden University has signed the ‘Think green, act green’ manifesto. The manifesto is the initiative of The Young Academy and The Green Young Academy, who are calling on universities…
