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.

Thermodynamics is one of the founding scientific pillars that has helped us better understand heat engines, biology, ecosystems, and even black holes. While it fundamentally describes large systems by examining the bulk behavior of their constituents, it is anchored in the statistical equivalence of…

The way organisms develop from the initial single-cellular state to a complex final assembly like the human body, and how the final body is maintained throughout life, is one of the greatest mysteries and it’s understanding one of the biggest scientific challenges.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

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

De Universiteit Leiden heeft onderzoeksinstituten gevestigd in Leiden en Den Haag.

The genetic information of all living organisms is contained in their DNA. Cells modify the degree of DNA compaction by epigenetics, which largely determines what genes are read out and which genes are transcriptionally silent.

This thesis aims to improve the detection from ultra-weak single emitter by enhancing their emission properties with plasmonic nanostructures. We exploit the wet-chemically synthesized single crystalline gold nanorods (GNRs) as our basic frameworks in the whole studies, simply because of their unique…

Waar gaan de quantummechanica, de relativiteitstheorie en de zwaartekracht elkaar vinden? Wat is het missende stukje? Of is er een compleet nieuwe theorie die alle vormen van materie elegant beschrijft?

The key characteristic of active matter is the motion of an emergent collection (such as a flock of birds), which is driven by the consumption of energy by its active components (i.e. individual birds).

This thesis is devoted to an in-depth examination of the various effects of disorder in the cuprate high-temperature superconductors.

With the help of quantum mechanics, digital quantum hardware may be able to tackle some of the problems that are too difficult for ordinary computers. But despite these expectations and the ongoing effort of the research community, reliable quantum computers are not yet realized in a lab setting.

Surface acoustic waves (SAWs) are mechanical waves that travel along the surface of a material and find many applications in modern technologies due to the ease of excitation on piezoelectric substrates via interdigital transducers (IDTs).

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…

Spectroscopic studies on fluorescent single molecules in organic condensed matter does not only provide information about the molecule itself, but also its near environment. By suppression of phonon-induced broadening of spectral lines through cooling to low temperatures, small changes in the spectral…

This dissertation combines the use of defined microenvironments, high-resolution fluorescence microscopy, and time-resolved analysis, to study intracellular and cellular motility.

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

We find ourselves in an era of transition, not just towards a more computing- and data-driven society but also away from unsustainable fossil fuels as an energy source.

In the first part of this thesis we study the geometry of folding patterns.

In this thesis, we describe the latest advances in SQUID-detected Magnetic Resonance Force Microscopy (MRFM).

The Standard Model (SM) of particle physics fails to explain several observed phenomena and is incomplete. In order to resolve this problem, one may extend the SM by adding new particles.

What physics controls the properties of quantum matter, such as how electrons flow inside high-temperature superconductors? This question has captivated the physics community and industry for decades, in part due to the great technological potential such materials have, but also because they have resisted…

The lipid membrane is a basic structural component of all living cells. Embedded in this nanometer-thin barrier, membrane proteins shape the membrane and at the same time respond to the shape of the membrane.

This thesis is a collection of theoretical works aiming at adjusting quantum algorithms to the hardware of quantum computers.

Studievoorlichting

Op 4 mei 2024, van 10.00-16.00 uur, vond aan de Gewandeweg 100 een feestelijke dag plaats, omdat werd gevierd dat medewerkers en studenten van de Leidse Faculteit der Archeologie al 50 jaar veldwerk doen in en rondom Oss in goede samenwerking met de gemeente Oss, de plaatselijke erfgoed- en archeologische…

Elf onderzoekers van de faculteit Wiskunde en Natuurwetenschappen staan op de 2021 Highly Cited Researchers-lijst van Clarivate Analytics. Slechts 0,1 procent van de wereldwijde onderzoekers komt in deze lijst voor, waarmee ze dus letterlijk één uit duizend zijn.

Woensdag 6 april nam Willemien den Ouden afscheid als Dean van de Honours Academy met een debat over referenda in de Europese Unie. Niesco Dubbelboer (initiatiefnemer Wet Raadgevend Referendum), Chris Aalberts (politiek journalist) en Wim Voermans (hoogleraar Staats- en Bestuursrecht) gingen met elkaar…

Na jaren van ontwikkeling is het moment eindelijk daar: een enorme cryostaat, een bijzonder geavanceerde vriezer die de gevoelige onderdelen extreem koud houdt, is vanuit Zürich in Leiden aangekomen. Het apparaat is het grootste onderdeel van METIS, een van de eerste instrumenten op ESO’s Extremely…

Erik Zürcher (1928 – 2008) geldt nog altijd als gezaghebbende bron in het onderzoek naar Chinees boeddhisme. Een nieuwe bundel met zijn publicaties is aanleiding voor een internationaal boeddhisme-congres in Leiden. Prinses Beatrix, die hem goed kende, is aanwezig bij de opening.
