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

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

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.

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…

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

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.

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.

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…

This thesis presents insights from our study of various correlated electron systems with a scanning tunneling microscope (STM). In ordinary metals, electron-electron interactions exist, but get substantially screened due to the sheer number of electrons.

n this PhD thesis, the recombination of different atomic lattices in stacked 2D materials such as twisted bilayer graphene is studied. Using the different possibilities of Low-Energy Electron Microscopy (LEEM), the domain forming between the two atomic layers with small differences is studied.

The thesis describes the use of electron paramagnetic resonance (EPR) spectroscopy, in continuous wave and pulse modes, to address the interaction of α-Synuclein (αS) with membranes and the aggregation of αS.

In condensed matter systems electron-electron interactions, negligible in everyday metals, can dramatically alter the electronic behavior of the system. Examples of such altered behavior include high-temperature superconductivity and modulation of the electron density.

In this thesis, we show how MRFM can usefully contribute to the field of condensed-matter.

Leiden University offers you several services related to career orientation and job application skills.

This article aims to contribute to the debate about citizen involvement in medical and social issues by studying co-production initiatives in The Hague.

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…
