Koenraad Schalm Group (String Theory and Experiment)
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…

Applied String Theory: Explaining Quantum Matter with Black Holes
Schalm

Physical reality of string theory demonstrated
String theory has come under fire in recent years. Promises have been made that have not been lived up to. Leiden theoretical physicists have now for the first time used string theory to describe a physical phenomenon. Their discovery has been reported this week in 'Science'.

Pulling the strings on anticancer immunity
Promotores: J. Jonkers, K.E. de Visser

Theoretical Physics
In the spirit of 'unity in diversity', our objective is to promote insight into and appreciation for the wonder that the same physical laws and mathematical concepts apply to the whole of nature, from the largest to the smallest energy and length scales. We strive for the application of abstract theoretical…

Theory
Many important topics in computer science, such as the correctness of software, the efficiency of algorithms and the modeling of complicated systems, depend on sound theoretical underpinnings. In the Theory group, we study these fundamental building blocks and develop verification methods to prove system…

Extended piano techniques : in theory, history and performance practice
Playing the piano with your forearm, plucking the strings, sawing through the piano: pianist Luk Vaes's doctoral dissertation covers all the techniques of play for which a piano is NOT designed. His defence ceremony will consist of three concerts and a public defence. 'Musicians were using the interior…

Black holes with ‘dreadlocks’ offer insight into quantum matter
Physicists understand little about quantum matter, which is a building block of future quantum computers. Theorists have now discovered that black holes with ‘dreadlocks’ harbor a similarly exotic order pattern, which makes calculations on quantum matter easier. Publication in Physical Review Letter…

Strings attached to future hightemperature superconductivity
The behaviour of strongly correlated electron systems, such as hightemperature superconductors, defies explanation in the language of ordinary quantum theory. A seemingly unrelated area of physics, string theory, might give physicists a better understanding of the weird behaviour of these kinds of…

Prominent physicist Maldacena gives Ehrenfest Colloquium
On November 21, theoretical physicist Juan Maldacena gives the Ehrenfest Colloquium. Maldacena is known worldwide as the inventor of AdS/CFT correspondence, which might be key to a theory of quantum gravity. Maldacena is winner of the prestigious Dirac Prize and the Breakthrough Prize in Fundamental…

Algebra, Geometry and Number Theory
The research of the Algebra, Geometry and Number Theory cluster tries to bridge the gap between abstract theory and the world of algorithms and applications.

The Death of Archaeological Theory
The Death of Archaeological Theory, edited by John Bintliff and Mark Pearce, addresses the provocative subject of whether it is time to discount the burden of somewhat dogmatic theory and ideology that has built up over the last 25 years.

Algebra, Geometry and Number Theory (MSc)
The master’s specialisation Algebra, Geometry and Number Theory at Leiden University is aimed at students who wish to acquire a profound knowledge of one of the areas within pure mathematics. There is a strong theme dealing with algebra and number theory as well as a strong theme dealing with topology…

Sentencing: theory and practice
Sentencing is becoming increasingly complex for the courts. Legal scholars and criminologists from Leiden document the process of sentencing in the Netherlands. They use this knowledge to advise legislators and those who implement this legislation on how to make sentencing more consistent and effect…

The Oxford Handbook of Morphological Theory
Edited by linguists Jenny Audring (Leiden University) and Francesca Masini (University of Bologna), this is a unique handbook with a focus on morphology theories rather than morphological data. It covers a wide array of morphological theories, from traditional twentieth century models to current theoretical…

Memory: concepts and theory
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…
