The thesis is part of a bigger project, the HEPGAME (High Energy Physics Game). The main objective for HEPGAME is the utilization of AI solutions, particularly by using MCTS for simplification of HEP calculations.

Our world is shrinking, or at least our electronic devices are. From PCs to mobile phones: everything is smaller and thinner. The smaller the chip, the better it can conduct electricity and pass on information.

In deep reinforcement learning, searching and learning techniques are two important components. They can be used independently and in combination to deal with different problems in AI, and have achieved impressive results in game playing and robotics. These results have inspired research into artificial…

Data Science & AI student Nataliia Bagan combines a passion for mathematics, language, and artificial intelligence. Her exceptional bachelor’s thesis on improving reasoning in large language models earned her a nomination for the Leiden Science Young Talent Award 2025.

Is there extra-terrestrial life out there? It now looks as though we can sketch out an answer to this enduring question. Leiden Observatory is helping to build new instruments to find the most promising exoplanets.

Leiden physicist Carlo Beenakker has received an honorary doctorate from the Bogoliubov Institute for theoretical physics in Kiev.

Self-assembly offers a promising route to create complex structures and materials using simple building blocks. Through, colloidal self-assembly, we can understand the governing principles of the self-assembly process and unlock its potential in diverse applications in materials science, photonics and…

The main focus of this thesis is the behaviour of two-dimensional materials, namely (anti)-ferromagnetic materials in the first two chapters, which show topological phases, and energetic square ice in the third and fourth chapter.

In order to test theoretical expectations concerning individual decision-makers' search in response to negative performance, Joris van der Voet conceptually disentangles problem-defining and solution-generation as two distinct search objectives.

Apps that can precisely identify shards, coins or heel bones: archaeology has embraced artificial intelligence. Alex Brandsen is working on a search engine that scans vast quantities of text from an archaeological viewpoint.

National and international actors have attempted to provide accountability for the events at Srebrenica in July 1995. This research project aims to draw lessons learned from those multiple efforts in assessing whether securing a measure of ‘justice’ for the victims has been successful and how national…

Are quantum computers the scientific breakthrough of our time? In this podcast, Carlo Beenakker, Professor of Physics at Leiden University, explains quantum technology.

This book investigates how the rulers of the Habsburg world empire developed and implemented a central maritime policy for the Netherlands and appointed an admiral of the sea or admiral-general for that purpose.

The ‘Stans Prize 2016' (for the best thesis, report or article produced by a CML student) has been awarded to Carlos Felipe Blanco Rocha. Other CML prizes were awarded to Henrik Barmentlo, Arnold Tukker and Coen van der Giesen.

Theoretical physicist Carlo Beenakker has been awarded a €2m Advanced Grant by the European Research Council (ERC). He will use this to try to create the ideal building blocks for a quantum computer: ‘braided’ Majorana fermions. An ambitious project that may just lead to a major breakthrough.

In this thesis, we examine various systems through the lens of several numerical methods.

With the rise of multi-drug resistant bacterial pathogens, the possibility of a post-antibiotic world is quickly becoming reality.

Ambient sound is a standard term used by sound practitioners to denote the site-specific background sound component that provides a characteristic atmosphere and spatial information in a sound work.

Since the 16th century, religious concerns have motivated the study of Old English and its speakers. In the 19th century, scholars turned to the study of Old English literature in particular to find traces of pre-Christian, ‘Germanic’ religion, as discussed in Eric G. Stanley’s seminal work The Search…

Search engines are getting better at answering our questions. And chatbots are increasingly likely to search the internet for relevant sources. ‘Search engines and chatbots will become more closely entwined’, says Professor Suzan Verberne.

In this thesis we study quantum transport phenomena on the nanometer scale, in two classes of materials: topological insulators with induced superconductivity and graphene superlattices.
