Om goed onderbouwde besluiten over complexe onderwerpen zoals het klimaat, recht en gezondheid te kunnen nemen, zijn wetenschappelijke resultaten van groot belang. Maar wetenschappelijke resultaten bevatten altijd een mate van onzekerheid. Binnen het onderzoek Communicatie over onzekerheden wordt onderzocht…

Single-molecule spectroscopy has become a powerful method for using organic fluorescent molecules in numerous applications.

In this thesis, we present new laboratory data of interstellar dust analogues.

This thesis describes a study from both a theoreticaL and an experimental point of view.

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).

The specialisation Science Communication and Society (SCS) concerns science communication in a broad sense. The program focuses on the link between science and society and covers knowledge and skills in the field of science communication.

There are many interpretations of quantum mechanics, and ultimately experiments are needed to verify or falsify these interpretations.

In this thesis, the research focuses on the properties of dark matter and dark matter haloes and how they connect with the galaxies we can observe in the Universe.

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

One of the most important puzzles in modern astrophysics is the nature of dark matter.

At the largest scales, two ingredients dictate the distribution of matter in the Universe. The first is dark matter, acting as an invisible scaffolding held together by gravitational forces.

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…

Stochastic resetting is simple enough to be approached analytically, yet modifies stochastic processes in a non-trivial way.

During my PhD research, I studied the photon statistics of light emitted by a microcavity that contains a single quantum dot (QD) on resonance.

For centuries astronomers studied the Universe by collecting light. Nowadays, we are living in times of great technological advancements, which allow us to explore our Universe in a new way - though gravitational wave radiation.

Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

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

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

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.

Molecular materials have been a subject of interest in fundamental research and applications for decades, and have been studied as bulk crystals, (thin) films and as individual molecules, due to the large variety in their properties. This dissertation explores pentacene crystals near the two-dimensional…

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…

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

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

Verreweg de meeste studenten kiezen voor de masteropleiding Astronomy. Je kunt ook doorstromen naar de masteropleiding Physics of kiezen voor een masteropleiding aan een buitenlandse universiteit.

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.

This thesis investigates catalytic reactions at the atomic scale using scanning tunneling microscopy (STM), with a focus on Fischer–Tropsch synthesis, a key industrial process that converts hydrogen and carbon monoxide into liquid fuels.

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

This thesis attempts to interrogate post-1991-2015 political development in Ethiopia, focusing on the political discourses espoused by the government and opposition, using the discourse analysis method and securitization theory.

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…

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