Optical cavities are useful tools to enhance the interaction between light and matter, which is important to make good quantum emitters. However, it turns out that the cavities themselves (without any quantum emitters) are already interesting objects to study.

In this thesis, we examine various systems through the lens of several numerical methods.

The dissertation describes TEM experiments on heterogeneous catalysts.

The thesis describes experimental steps towards reduction of friction on the macroscopic scale by scenarios of thermo- and superlubricity well-known on the nanoscale.

Een nieuwe computersimulatie toont de veelbelovende mogelijkheden van het opbloeiende veld topologie. Slim ontworpen mechanische structuren dragen geluid exclusief in één richting en zijn resistent tegen fabricagefouten. Publicatie op 17 juli In Nature Physics.

In het kader van Big Cat Month interviewde National Geographic professor Hans de Iongh, gastonderzoeker bij het Centrum voor Milieuwetenschappen Leiden (CML), over bescherming en behoud van leeuwenpopulaties in Afrika.

CrO2, a half-metal ferromagnet, has shown great promise for superconducting spintronics applications for nearly two decades.

In this thesis, time-lapse fluorescent microscopy plays a pivotal role in investigating functional materials within living cells as well as the migratory behaviour of neural progenitor cells.

The studies in this thesis are focused on the physical effects in the flat band materials. The results contain the discovery of strong enhancement of RKKY spin-spin interactions with specific geometric arrangement and dynamical generation of excitonic order parameter with high magnitude.

This thesis examines silicon pore optics (SPO), a technology that exploits silicon wafers from the semiconductor industry to create extremely high quality X-ray optics, by studying its manufacturing process, applications, and prospects.

A Josephson junction is a device where a thin insulating barrier or a nanostructure is placed between two superconducting leads. Such a junction is essential to superconducting qubits that store quantum information due to its anharmonic spectrum.

Make more fluid: In condensed matter systems, electrons can acquire unusual properties from their interaction with the atomic lattice.

Gold nanorods are biocompatible nanoparticles that present an excellent two-photon signal that can be used to get high spatial resolution inside living cells. Gold nanorods are photostable and therefore can be followed inside cells for long time, with possible applications as trackers in live cells.

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.

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

In this thesis I describe the results of Pulsed Interleaved Excitation and Fluorescence (Cross) Correlation Spectroscopy (PIE-F(C)CS) combined with single-pair Förster Resonance Energy Transfer (spFRET) used to study dynamics in single nucleosomes, which depends on subtle differences in the length of…

In de geest van ‘eenheid door verscheidenheid’ is ons doel het bevorderen van inzicht in en waardering voor het wonder dat dezelfde natuurkundige wetten en wiskundige concepten van toepassing zijn op de hele natuur, van de grootste tot de kleinste energie- en lengteschalen. Wij streven naar de toepassing…

De ‘Verdieping Bewaken en Beveiligen’ brengt verdieping aan op actuele gebeurtenissen en ontwikkelingen gerelateerd aan het stelsel Bewaken en Beveiligen.

De complotten over corona ontwikkelen zich langs vertrouwde lijnen. Maar opmerkelijk is dat ze niet alleen floreren in de marge, maar in sommige landen in de hoogste regionen opduiken. Jelle van Buuren, universitair docent aan de Universiteit Leiden, onderzocht complottheorieën rondom het coronaviru…

Binnen het Institute of Security and Global Affairs is het onderzoek georganiseerd rond zeven domeinen:

Een compacte maar theoretisch innovatieve ontdekkingstocht naar hoe Islamofobie en radicalisering op elkaar inhaken en elkaar versterken.

Een systematische literatuurstudie naar de intergenerationele overdracht van extremistische denkbeelden binnen de gezinscontext.

De bachelor Cybersecurity & Cybercrime leidt je op voor de doorstroom naar een vervolgopleiding op masterniveau.
