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

This dissertation consists of two parts, each of which considers a different research area related to random interval maps. In the first part we are interested in random interval maps that are critically intermittent.

Enkele keren per jaar organiseert het Europa Instituut een ‘Meet the Author’ bijeenkomst. In het kader van deze nieuwe lezingenreeks komen externe academici naar Leiden om te spreken over een recente publicatie. ‘Meet the Author’ bijeenkomsten vangen aan met een gesprek tussen een lid van het Europa…

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.

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).

Organisms often need to adapt more efficiently and devise new strategies for surviving difficult ecological circumstances.

Gibbs measures, as used in Statistical Mechanics, have a definition that is remarkably similar to the definition ofg-measures, used in dynamical systems.

Recentelijk is een Special Issue van de European Journal of Criminology verschenen, die is samengesteld door Marieke Liem, Universitair Docent Criminologie bij het Instituut voor Strafrecht & Criminologie, en William Pridemore.

This dissertation presents new cryptographic protocols, which can be divided into two families.

Continuous optimization is never easy: the exact solution is always a luxury demand and the theory of it is not always analytical and elegant.

The redox-conversion reaction of metal-disulfide and metal-thiolate complexes are important, as they may shed light on electron-transfer reactions that often occur in Nature.

In this thesis it is posed that the central object of preference discovery is a co-creative process in which the Other can be represented by a machine. It explores efficient methods to enhance introverted intuition using extraverted intuition's communication lines.

This PhD thesis concerns the topic of arithmetic geometry. We address three different questions and each of the questions in some way is about counting how big some set is or can be.

We consider the propagation of electrical signals through nerve fibres.

This thesis considers multi-prover commitment schemes whose security is based on restrictions on the communication between the provers.

Of all the mass in our Universe, 80% is thought to consist of a hypothetical and invisible substance called dark matter (DM).

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

Constraint multi-objective optimization with a limited budget for function evaluations is challenging. This thesis tackles this problem by proposing new optimization algorithms. These algorithms are applied on holistic ship design problems. This helps naval architects balance objectives like cost, efficiency,…

Majorana fermions in superconductors are the subgap quasiparticle excitations that are their own antiparticles.

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.

In the early universe, the dynamics of the Higgs field can give rise to many interesting phenomena.

The aim of the research presented in this thesis was to develop new methods forchallenging systems in liquid-state NMR using paramagnetic effects generated by thetwo-armed probe CLaNP-5.

This thesis investigates the contribution of quantum computers to machine learning, a field called Quantum Machine Learning. Quantum Machine Learning promises innovative perspectives and methods for solving complex problems in machine learning, leveraging the unique capabilities of quantum computers…

In my research, we developed a method to distinguish knots. A knot is a mathematical depiction of the everyday knot that occurs in ropes and cords.

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

Sanne Kellij en collega's hebben 142 artikelen systematisch geëvalueerd, waarbij ze bewijs onderzochten voor drie hypothesen over de relatie tussen slachtofferschap en sociale informatieverwerking.

Welk effect heeft een verwerkingsvoorkeur op de omgang met regels?

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…
