Quantum computers deserve their own quantum internet. This is a network that dispatches information not in the form of bits - ones and zeros - but rather as qubits, just like in the quantum computer itself. In the view of Dirk Bouwmeester, a professor in Leiden’s Quantum Matter & Optics research group,…

This thesis aims to demonstrate how the achromatic nature and design flexibility of liquid-crystal optics can be used to improve high-contrast imaging instruments to facilitate detailed exoplanet characterization.

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

The winner of the highest scientific distinction in mathematics, an explanation for wine tears and much more mathematical theory and application. From 8 to 12 July, 550 mathematicians will meet in the center of Leiden to discuss differential equations.

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

The MSc programme Physics offers 5 research-oriented specialisations where you can focus on Theoretical Physics, Quantum Matter and Optics, Biological and Soft Matter, Cosmology or Casimir pre-PhD. You can also combine Physics with education, management or science communication.

Are Weyl particles the ideal conductors? Do cells without a cell wall play a role in chronic Tuberculosis infections? Carlo Beenakker and Dennis Claessen want to answer these questions. They both received a KLEIN grant from the NWO. With these grants, NWO wants to stimulate innovative, fundamental r…

How is it that the internet works so well, with billions of users sending millions of gigabytes all together every day? That's because the foundation of the internet is solidly set up. Yet sometimes there are problems on the internet. For example, when certain systems misbehave and disrupt the routing…

The CIGR brings together a diverse range of unique expertise in genome research rooted in biology, chemistry and physics. Members of the CIGR investigate genome folding and genome transactions. An important aspect is direct as well as long term relevance for medicine. The available expertise extends…

The CMCB brings together a diverse range of unique expertise in microbial cell biology. Members of the CMCB investigate both model and non-model organisms, bacteria and archaea, pathogens and non-pathogens.

Our group operates at the cross-roads of different disciplines: molecular and cellular microbiology, biochemistry, structural biology and biophysics. The group harbors expertise in a multitude of molecular and cellular approaches including:

SALTSWAT -- a project which combines the Spaces for Active Learning & Teaching and the Support wtih Active Teaching -- began in Mid-2019 and is running in pilot until the summer of 2020. The purpose of the project is to find answers to the question of how to systematically accelerate 'active teaching…

The Leiden Institute of Physics (LION) offers bachelor and master level education in physics at Leiden University.

Astronomer Koen Kuijken and physicist Tjerk Oosterkamp have each been awarded a major subsidy by NWO. The funding will allow them to construct new research facilities.

We have recently discovered that there are biological proteins that phase separate out of solution much the way oil will de-mix from water (see movie). These form dense, liquid-like phases called protein condensates.

Our DNA molecules are packaged by proteins in compact structures. The aim of this project is to understand how modern gene editing techniques nevertheless get access to their target in the DNA.

This thesis contains results on the arithmetic and geometry of del Pezzo surfaces of degree 1.In Chapter 1 we give the necessary background, assuming the reader is familiar with algebraic geometry.

This liber amicorum is a tribute to Prof. dr. ir. Hans H. de Iongh, associate professsor at the Institute of Environmental Sciences (CML) of Leiden University and guest professor at the University of Antwerp, on the occasion of his retirement on 27 October 2016.

The worldwide race to the quantum computer is in full swing. This computer can take on computing tasks that we can only dream of today, such as finding proteins that can be used as medicines in seconds flat. Leiden physicists have discovered how the Majorana particle can be used as a building block…

This thesis describes the Multi-site All-Sky CAmeRA (MASCARA), which consists of two small robotic telescope designed to detect exoplanets around the brightest stars in the sky.

This thesis is a collection of experimental attempts to enhance photoluminescence of fluorescent molecules and quantum dots with single gold nanorods (GNRs) and relevant applications.

This PhD-research is conducted to test the hypothesis that Gutenberg and consorts developed a standardised and even unitised system for the production of textura type, and that this system was extrapolated for the production of roman type in Renaissance Italy.

Are there other planets like the earth, and will there also be life? Astronomers study planets around stars other than the sun, with the aim to find out what kind of gasses their atmospheres are made up with.

To study how planetary systems come into existence we study much younger systems still in formation.

Develop EPR instrumentation and methodology to investigate intrinsically disordered proteins (IDPs).

Surface plasmons (SPs) are surface waves at the interface between a dielectric and a good metal, and are formed by the interaction between light and the free electrons at the metal-dielectric interface. They provide strong field confinement for optical fields, opening new possibilities for enhanced…

A large diversity of exoplanetary systems has been found, but it is still unclear what drives this diversity.
