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…

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

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

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

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.

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…

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.

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

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 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.

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

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

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).

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.

Hoe kan formatieve assessment worden ingezet om het leren van docenten te bevorderen? Dit boek bevat diverse onderzoeken naar professionaliseringsaanpakken en cursussen waarin formatieve assessment wordt aangewend met het oog op het leren van docenten.

PhDArts co-director Dr. Janneke Wesseling’s e-book ‘De volmaakte beschouwer, De ervaring van het kunstwerk en receptie-esthetica’ was recently published. The key question of the book is: how does the work of art work?

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 sociale ontwikkeling is één van de belangrijkste domeinen van kwetsbaarheid bij Jonge kinderen met een extra X- of Y-chromosoom. Het is daardoor voor hen uitdagender om sociale signalen te signaleren in hun omgeving, die te verwerken en er gepast op te reageren.

Dynamical systems describe the evolution of objects in a space over time and may be used to model physical phenomena. Due to this, much research is dedicated to understanding the mathematics of dynamical systems.

In this dissertation, matching, entropy, holes and expansions come together. The first chapter is an introduction to ergodic theory and dynamical systems.

Electrons in a crystal lattice have properties that may differ from those of a free electron in vacuum.

It is an established fact that the Standard Model has to be extended to explain the so-called Beyond the Standard Model (BSM) phenomena: dark matter, matter-antimatter asymmetry of the Universe and neutrino flavour oscillations.
