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

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

The interest of this thesis lies in spin transport in normal metals and superconducting half-metallic junctions.

In this thesis we use Josephson and noise scanning tunneling microscopy for the study of conventional, unconventional (iron-based) and disordered superconductors. On the one hand, Josephson scanning tunneling microscopy allows us to directly visualize the superfluid density with high spatial resolut…

Tjerk Oosterkamp of the Leiden Institute of Physics managed to do the first-ever measurement of gravity on a tiny particle - just 0.43 milligrams - where the quantum regime starts. He explains in Physics World why this is so challenging.

Cell-based medicinal products (CBMPs) show great promise when it comes to the treatment of genetic disorders. However, there is limited knowledge about CBMP stability during their production, storage, and administration to patients. The main focus of my research is the characterization of CBMPs using…

Research practice, funding agencies and global science organizations suggest that research aimed at addressing sustainability challenges is most effective when ‘co-produced’ by academics and non-academics. Co-production promises to address the complex nature of contemporary sustainability challenges…

To overcome the limitations of slow and error-prone quality control, this research develops an advanced 3D imaging method for the rapid and reliable detection of internal defects in critical sectors.

Jianfeng Ge and Milan Allen of Leiden University look for majorana quasiparticles using shot noise measurements

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

Patterned detectors are an existing technology that can be found in almost all color cameras.

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.

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

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.

For the first time, a group of international and interdisciplinary researchers led by Karline Janmaat and her former MSc Student Chirag Chittar, have tested the several hypotheses on music simultaneously in a modern foraging society during their daily search for tubers – their staple food. They found…

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.

On the 15th of April, Shaoyu Wang successfully defended a doctoral thesis. Leiden University Centre for Linguistics congratulates Shaoyu on this achievement!

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.

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.

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

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.

Toll-like receptors (TLRs) are central components of the innate immune system, functioning as pattern recognition receptors that detect microbial- and damage-associated molecular patterns and initiate antimicrobial and inflammatory responses.
