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

Physics and Engineering Approaches to Biomedicine and Pharmacology

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.

We study the dynamics of individual emitters in micro cavities.

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

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?

Lineke is a Master’s student in European Law.

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 and chemist Hermen Overkleeft.

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

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.

This minor is developed for third year students and is only accessible for bachelor students who have obtained their ‘propedeuse’, we are sorry to tell you HBO students cannot apply.

The CIGR comprises research groups from the Institute of Biology Leiden (IBL), the Leiden Institute of Chemistry (LIC), the Leiden Academic Centre for Drug Research (LACDR) and the Leiden Institue of Physics (LION).

In Quantum mechanics, particles can be in multiple positions simultaneously. Yet, when a measurement is made, the particle is found only in one place. Technology has come to a point where we may design experiments that will tell us how.

Developing computational algorithms for structural biology -A high resolution, three dimensional view of a molecule provides detailed information that help elucidate its function: by knowing the exact arrangement of atoms in a molecule, we can understand disease, develop drugs to combat them and improve…

This study aims to make a practical contribution to a new understanding and use of 3D reconstructions, namely as ‘laboratories’ to test hypotheses and visualize, evaluate and discuss alternative interpretations.

This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

This thesis describes the structural and biochemical characterization of the β-lactamase BlaC from Mycobacterium tuberculosis (Mtb), and the Alr and YlmE proteins from Streptomyces coelicolor A3(2).Mtb is the main cause of tuberculosis.

Long-distance Trade in Early Medieval Landscapes (ca. 6th-12th centuries)

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

A 35-year-old uranium crystal will not disclose its secret: what causes a dramatic phase transition at 17.5 Kelvin? Thanks to a new artificial intelligence approach, half of the possible explanations are excluded, but the definitive answer remains to be found. 'It is very frustrating', says physicist…

Kidney failure is a serious issue because kidneys cannot regenerate themselves after injury. A possible solution consists of artificially growing healthy kidney tissue. To achieve that, scientists first need to understand kidney development during the earliest stages, in the fetus. Leiden researchers…

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 quantum nature of matter and light has grown into a broad and fruitful research field for theorists and experimentalists alike. It combines foundational research with toward applications, the most well known of which is the quantum computer.

Lecture

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

Leiden University supports refugee students by improving access to education, removing obstacles to academic success and encouraging contact with fellow students and staff. In doing so, we strive to contribute to an inclusive climate at Leiden University.

High throughput microscopy

Since the start of academic year 2020-2021 LUGO started working on new goals to increase the effect of our work within Leiden University. Below, the goals for the current academic year will be explained. For now, LUGO will continue to work on the accomplishment of the goal called 'Reduction of single…

A high performance computer or supercomputer owes its massive processing capacity to the fact that it chops a single overarching task into a whole series of smaller tasks. It simultaneously tackles each of those smaller problems.

Leiden University offers the possibility of pursuing a doctorate in the form of a ‘double doctorate’: a doctorate that is completed simultaneously at two or more universities. This can either lead to a joint doctoral degree (one single diploma awarded by both institutions) or a double doctorate (each…

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…
