Using 2D materials, physics student Romme van der Kemp developed a nanochip that is extremely small ánd scalable. This is needed to make all kinds of technologies better, faster and smaller. He has been nominated for the FWN Young Talent Award 2023 for his research.

On Friday November 2nd 2018, eLaw, the Center for Law and Digital Technologies at Leiden University, will host a one-day conference on the new EU Data Protection Law that came into force earlier this year.

This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.

In unconventional high temperature superconductors, supercurrent vortices are known to spoil the Landau levels. In this thesis the emergence of Landau levels is studied in different types of superconductors: Weyl superconductors, and the Fu-Kane heterostructure.

This thesis consists of two subjects, that are both a consequence of radiation pressure.

On 3 November 2022, Mariëlle Bruning, Professor of Children and the Law, spoke as an expert on child protection at a roundtable discussion with Dutch Lower House members of the Standing Committee on Justice and Security.

Leiden University has written an advisory report at the request of the Ministry of Justice and Security on a legislative bill to improve legal protection in youth protection. The report acknowledges the improvements that the proposed legislation would bring, but also provides criticism.

This thesis focuses on amyloid proteins, a class of proteins that convert into amyloid fibrils.

The main objective of this thesis was to develop clinically relevant survival models for patients with high-grade soft tissue sarcoma of the extremities, in particular the development and validation of prediction models for use in clinical practice.

A plasma is an ionized gas with very low electrical resistivity. As such, magnetic field lines are 'frozen in' and move with the fluid. Magnetic field lines that are linked, knotted and tangled, cannot be undone by the fluid motions.

Is the current existing legal framework on compulsory and voluntary care - for vulnerable young adults (between the ages of 18 to 23) - in need of revision? And if so, what kind of amendments would be advisable?

Vedran Dunjko (LIACS and applied Quantum algorithms (aQa) Leiden) and Tomoyuki Morimae (Kyoto University) are to collaborate with Qu&Co. Qu&Co is a leading European developer of quantum software.

I am a PhD candidate in the Applied Quantum Algorithms group, supervised by Prof.dr. V. Dunjko and Dr. H. Wang. My current research direction is algorithm design and optimization theory for quantum machine learning.

Materials with strongly correlated electrons show some of the most mysterious and exotic phases of quantum matter, such as unconventional superconductivity, quantum criticality and strange metal phase.

The High-Tech Innovation specialisation consists of a 60 EC track alongside the students' core MSc programme: Astronomy, Chemistry, Computer Science, Mathematics and Physics.

Leiden has a strong tradition in theoretical physics, thoroughly linked with experimental disciplines.

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

NWO has awarded a €392k Projectruimte grant to physicists Koenraad Schalm and Jan Zaanen to study ‘strange metals’. These materials are alleged to follow the bizarre laws of quantum mechanics even at everyday length scales.

On 12 September 2019, Michiel Rhoen defended his thesis 'Big Data, Big Risks, Big Power Shifts: Evaluating the General Data Protection Regulation as an instrument of risk control and power redistribution in the context of big data'. The doctoral research was supervised by Prof. G.J. Zwenne and Prof.…

This collection includes six short policy-focused contributions exploring how legislation and policy on counter cyber terrorism unfold at the national level in the United States, the United Kingdom, China, Russia, France, and at the regional level of the European Union.

To be eligible for Research in Physics, Quantum Matter and Optics at Leiden University, you must meet the following admission requirements.

That a switching protein plays a role in protecting a plant from too much sunlight was already known, but how exactly was not yet understood. The research group of Anjali Pandit has now discovered that this protein changes shape when there is too much sunlight. The results have been published in Nature…

On Wednesday 13 December at 13.45 hrs Jaap Wieland will defend his doctoral thesis entitled ‘De bescherming van concurrentiebelangen in het bestuursrecht’ (the Protection of Competition Interests in Administrative Law) at the Academy Building of Leiden University. His supervisors are Professor Willemien…

Tjerk Oosterkamp's group is conducting what is perhaps the coldest research in the world. The researchers have cooled a sensor to below 2 millikelvin - almost as cold as absolute zero. This allows them to make extremely sensitive measurements. PhD candidate Jaimy Plugge helped build the setup: ‘We are…

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.

Children are not always immediately helped due to staff shortages. For years, youth protection agencies have used an emergency protocol. Mariëlle Bruning, Professor of Children and the Law in ‘Trouw’: ‘It’s shocking that an emergency protocol has been used for three years.’
