Early time-resolved experiments by Frauenfelder on the ensemble of the kinetic rebinding of CO to myoglobin molecules resulted in a stretched exponential relaxa-tion due to a very large spread of the reaction rates of individual molecules.

Throughout the history of computer science, a major challenge has been how to assert that software is free of bugs and works as intended. Software bugs can lead to serious negative impacts on any software system. Throughout the main body of the thesis, we implemented a series of studies on exploring…

Catalysis is of extreme relevance in the production of everyday materials and plays a central role in many aspects of our life.

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.

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.

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

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…

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.

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.

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…

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…

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

Bestaan er objectief correcte oplossingen voor ethische dilemma’s? Of is de ethiek altijd een kwestie van jouw mening tegen mijn mening? Hoe weet je wat je moet doen? Wat voor iets is ethiek eigenlijk? Kun je expert zijn in ethiek?

Welk effect heeft een verwerkingsvoorkeur op de omgang met regels?

The research of the Applied Mathematics cluster is concerned with such diverse topics as dynamical systems, representation theory, differential equations and pattern recognition.

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.

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

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,…

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

Vast, often populated, areas in dryland ecosystems face the dangers of desertification.

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.

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

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

In populations with a seed-bank, individuals can temporarily become dormant and refrain from reproduction until they can become active again. The repository of all dormant individuals in the population is called the seed-bank. Seed-banks are observed in many taxa, including plants, bacteria and other…

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

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.

Artful Mathematics: The Heritage of M. C. Escher

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

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.

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.
