Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

In some condensed matter systems, such as the surface of a 3D topological insulator, the electrons are effectively massless and we must necessarily use the massless Dirac equation to describe them.

This thesis studies the geometry of representation varieties and character stacks. These are spaces parametrizing the representations of a finitely generated group, typically the fundamental group of a compact manifold, into an algebraic group G.

After 2 years of planning, designing, testing and adjusting, the brand-new low-vibration physics lab at the new Gorlaeus Building of the Science Campus is working like a charm and ready to make its mark in the world of science. Also, the renewed facility for the production of liquid helium is all do…

Light reflects from a mirror, but where exactly does this reflection happen? Well, it depends, Martin van Exter and Corné Koks discovered. Their precise calculations, published in Optics Express, are important for designing optical cavities for quantum communication.

More than 5,000 exoplanets have been found over the past couple of decades. These exoplanets show a tremendous diversity, ranging from scorching hot Jupiters, common super-Earths, to widely separated super-Jupiters on the planet/brown dwarf boundary.

Prof. Dr. Richard Gill has recently joined as a member of the Foundational Questions Institute (FQXi). FQXi is an international association of scientists who explore the foundations of physics and cosmology.

Experimental physicist Jan Aarts has received a FOM Projectruimte grant of 545,000 euro. He will use the budget to study the interaction between superconducting currents and ferromagnetism. In the future, this might lead to computer memory with negligible energy consumption.

Because the last Elfstedentocht celebrates its twentieth anniversary, New Scientist spoke with physics professor Tjerk Oosterkamp about his research on the slipperiness of ice and his passion for skating on natural ice.

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…

Christopher Berg Smiet, who defended his thesis at LION with Dirk Bouwmeester, won the Christiaan Huygens prize for his thesis '‘Knots in Plasma’. On 7 October, he received a certificate, a bronze statuette and ten thousand euros.

One of the most important correlation functions in physics, especially in cosmology, is the energy density, which describes how much energy is present at each point in spacetime due to matter fields. A key contribution to the energy density of the primordial universe comes from gravitational waves (GWs),…

On Thursday 3 November, Leiden University celebrated the official opening of two wall formulas in the Leiden city centre. Snell's law and the formula for the Lorentz force shine on two walls in the heart of Leiden. TV channel Omroep West interviewed the initiators Sense Jan van der Molen and Ivo van…

The project has been done in the Quantum Matter and Optics group under the supervision of Prof.dr.ir. T.H. Oosterkamp and Dr.ir. S.J. van der Molen . The title of the presentation is: ''Friction of ice skating.

Leiden Physicists have found evidence for the Berry-force that could be used for driving tiny nanomotors, just like a river drives a water wheel. Nanomotors could be used for drug delivery in the human body. Publication in Beilstein Journal of Nanotechnology.

Since 2015 the United Nations have declared 11 February the International Day of Women and Girls in Science. Leiden University organized a public event for over a hundred visitors. In between a lecture on the building blocks of life and a talkshow on the impact of science on society, high school students…

LCD screens use liquid crystals which have a high degree of order, even though they form a fluid. A new theory maps out the interplay between order, temperature and symmetry. Publication in Physical Review X.

From July 22nd to August 1st, the Leiden Institute of Physics organizes its annual summer school, titled ‘Modern Physics at all Scales’.

From 16 to 26 July, the Leiden Institute of Physics organizes its annual summer school, titled ‘Modern Physics at all Scales’.

Milan Allan has received the Bryan R. Coles Prize at the International Conference on Strongly Correlated Electron Systems (SCES) in Prague.

After seven years, Eric Eliel resigns as scientific director of the Leiden Institute of Physics (LION). On April 18th, LION hosts a farewell party and a week later Eliel will officially hand over his tasks to Jan Aarts. We spoke with him about his term as director, in which among others a new science…

This header image was once elected Image of the Week by De Volkskrant and won second place in the LION Image Award. The research behind it is no less successful if we’re counting prizes. Last August, group leader Tjerk Oosterkamp was awarded an NWO Projectruimte grant, and now NWO-TTW grants him an…

Superconducting devices such as SQUIDS (Superconducting Quantum Interferometry Device) can perform ultra-sensitive measurements of magnetic fields. Leiden physicsts invented a method to 3D-print these and other superconducting devices in minutes.

NWO has granted Jan Aarts en Vadim Cheianov a Physics Projectruimte, a granting instrument for small-scale projects that propose innovative fundamental physics research that has a scientific, industrial or social urgency.

Leiden physicists have been awarded 1.5 million euros for developing a hybrid microscope that provided nanometer-resolution. 'The idea is to combine the resolution of electron microscopy with the pros of optical microscopes.'

Your tuition fee depends on a number of factors, such as your nationality and your previous Dutch higher-education qualifications.
