Geometric phases lead to a nontrivial interference result when an electron's different quantum mechanical paths choices encircle a magnetic coil in an Aharonov-Bohm experiment.

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

In human cells, a meter-long DNA is condensed inside a micrometer-sized cell nucleus. Simultaneously, the genetic code must remain accessible for its replication and transcription to functional proteins.

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.

Understanding interactions in quantum many-body systems remains one of the most profound and difficult challenges in condensed matter physics.

The overarching goal of this thesis is to set the foundations, but also make the first essential steps towards establishing a comprehensive, mesoscopic, hydrodynamic theory of epithelial tissues. The stage is set by an exhaustive study of topological defects in passive p-atic liquid crystals, singularities…

The quantum nature of matter and light has grown into a broad and fruitful research field for theorists and experimentalists alike. It combines foundational research with toward applications, the most well known of which is the quantum computer.

The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.

The human body consists of hundreds, perhaps thousands of different types of cells, each with different morphologies and functions, despite having the same genome.

In this work, we investigate the minute circular dichroism effects of single nanoparticles.To this aim, we apply photothermal imaging with a polarization-modulated heating beam.

For each living organism health is ensured by correct functioning of its cells. Cells therefore have elaborate methods for regulation of their proteins.

Electron microscopy has become an extremely important techniquein a wide variety of elds.

The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.

In this thesis unconventional tools based on fluidic interfaces were developed to study the surface and interfacial chemistry of graphene, to characterize the intrinsic properties of graphene, to disentangle the effects of substrate and of the environmental factors, and to improve handling protocols…

Keeping our planet healthy in a just and responsible way.

This thesis explores how electron paramagnetic resonance (EPR) spectroscopy can be used to investigate key biochemical processes.

Quantum position verification (QPV) - the subject of this thesis - is a novel way to authenticate unknown nodes in a quantum network without the need to physically meet up.

Pancreatic ductal adenocarcinoma (PDAC) is among the cancers with the highest mortality rate, despite a relatively low incidence.

The ultimate goal of cosmologists is to find a cosmological model able to explain the current observational data.

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.

All the data stored and processed by our computers is encoded as sequences of zeros and ones, called bits. Quantum computers offer an alternative to this traditional way of encoding and manipulating information.

Jorrit Rijpma, Professor of European Law, together with Greek independent researcher Apostolis Fotiadis, investigated the European Commission’s enforcement powers in relation to fundamental rights compliance at Europe’s external borders. The study was commissioned and funded by the Greens Group of the…

The Dutch government chairs the EU council this year. Researchers from Leiden took this opportunity to reflect on the future of the European Union and to give recommendations where possible. The book will be presented on Friday 29 April, 10.15 AM in Nieuws Poort (Den Haag). Attending the event are Ankie…

On Wednesday 7 June 2023, Dr Yvonne Erkens, Kate Verhoeff, Emma Snel, and Fleur Walravens of the Department of Labour Law in Leiden, gave a presentation on The Database of Business Ethics for the Oxford Business and Human Rights Network (OxBHR) at the University of Oxford.

Many thanks for visiting the Master’s Open Day on Friday 2 November! We hope that you enjoyed the day and that all your questions were answered.

This year The Netherlands once again chairs the EU Council. In the book ‘Fit for the Future’ Leiden researchers reflect on the priorities that the Dutch presidency has put forward for 2016 and raise the question: is the EU fit for the future?

Danique Reidsma, student Economics, Policy and Management (EBM) at Leiden University, recently gave a presentation at a symposium of the Dutch Association of Social Security (NGSZ) in The Hague. She presented her own research around the question of whether eHealth can help to keep health care expenditure…
