We review the state-of-the-art in the theory of dissociative chemisorption (DC) of small gas phase molecules on metal surfaces, which is important to modeling heterogeneous catalysis for practical reasons, and for achieving an understanding of the wealth of experimental information that exists for this…

From ransomware to Citrix traffic jams: over the past few months Dutch organisations were regularly brought to a standstill by serious cyber attacks. We can only face these threats by standing as one, and universities and government should take the lead. These are the words of Leiden professors Bibi…

In the first part of this thesis we study the geometry of folding patterns.

This thesis mainly focuses on cross-modal retrieval and single-modal image retrieval via deep learning methods, i.e. by using deep convolutional neural networks.

We study the dynamics of individual emitters in micro cavities.

The local ordering of atoms at the surface of a metallic particle determines its catalytic activity and selectivity. As energy systems of the future will be based on efficient catalytic conversion of small molecules in closed cycles, we study how structural effects of catalysts can be used to our ad…

How is energy really dissipated on the atomic scale when sliding objects slip over a single lattice spacing?

The stratum corneum (SC) plays a fundamental role in the barrier function of the skin. The SC consists of corneocytes embedded in a lipid matrix.

Research in the van Exter lab focuses on quantum aspects of light and light-matter interaction. One of our long-term goals is to develop a reliable quantum memory, based on a single emitter in an open micro cavity.

In this thesis I describe the results of Pulsed Interleaved Excitation and Fluorescence (Cross) Correlation Spectroscopy (PIE-F(C)CS) combined with single-pair Förster Resonance Energy Transfer (spFRET) used to study dynamics in single nucleosomes, which depends on subtle differences in the length of…

Why is there not just one single global law for cases of defamation in cross-border communication mediums such as the internet? Which courts are to be called on in such cases? And is it permissible to hold an intermediary instead of a content provider liable?

The Royal Netherlands Academy of Arts and Sciences (KNAW) selects prominent researchers as members based on their scientific achievements. On September 17th, the KNAW will install 21 new members, including Leiden physicist Michel Orrit.

Mashaghi lab conducts research at the interface of physics, engineering and biomedicine. We develop and use theoretical and experimental approaches to address basic and applied research problems.

The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.

The Joan van der Waals colloquium is an ongoing bi-weekly lecture series.

Relevant publications of the CIGR participants.

Almost all languages of Europe and of a large part of western Asia belong to a single language family, which is called Indo-European, and which includes modern languages like English, Dutch, Russian, Farsi, but also ancient ones like Ancient Greek, Latin, Hittite and Sanskrit.

Shape and biological function are tightly connected. Physical descriptions are used to connect the shape of a biological system with its function.

The Division of Systems Pharmacology and Pharmacy (SPP) aims to develop precision medicine approaches to characterize and predict variation in treatment response and enhance translational drug development strategies.

Performances of solo keyboard repertoire can sound more or less polyphonic depending on the performer’s use of divergence in expression.

The research at The Metabolomics & Analytics Centre is centered around developing innovating analytical methods to enable metabolomics-driven systems biology in personalized health strategies.

Gold nanoparticles show surprisingly strong interactions with light in the visible range, which can be divided into scattering, absorption, and photoluminescence.

Biopolymer sequencing with graphene edge-based tunnel junctions has the potential to overcome current limitations with the third generation of sequencing based on biological nanopores.

This thesis advances our understanding of lipid uptake, a vital first step in lipid metabolism, by developing innovative click chemistry-based tools to study how immune cells internalize lipids.

Understanding interactions in quantum many-body systems remains one of the most profound and difficult challenges in condensed matter physics.

The surface and the edges of graphene are expected to provide higher sensitivity and specificity in detecting and characterizing single molecules. However fundamental physical limits exist in reaching an ultimate precision in detecting the dynamics of chemical and biological systems. The research in…

An important award like the Spinoza Prize, the 'Dutch Nobel Prize', generates lots of media attention. An overview.

On May 2nd, Elena Karvovskaya succesfully defended her doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Elena on this great result.

The guest rooms are located on the top floor of our institute.

This monograph focuses on clustering of objects in high-dimensional data, given the restriction that the objects do not cluster on all the attributes, not even on a single subset of attributes, but often on different subsets of attributes in the data.

This volume offers an innovative analysis of Roman political culture in Italy from the first to the sixth century AD on the basis of seven case studies.

Operators in the Lexicon opens with an old chestnut: why are there no natural single word lexicalizations for negations of the propositional operator and and the predicate calculus operator all: why neither *nand nor *nall?

The Mathematical Institute is one of the eight institutes of the Faculty of Science. The institute operates as a single unit defined by the activities of its members.
