This volume provides an authoritative, cutting-edge resource on the characteristics of both technological and social change in warfare in the twenty-first century, and the challenges such change presents to international law.

American physicist and quantum computing pioneer Seth Lloyd is the 65th Lorentz professor. He will deliver the Ehrenfest lecture on 5 June, and several more lectures on quantum computing on 11, 18 and 25 June.

This report concerns itself with terrorist technical innovation, particularly with regards to terrorists’ incorporation of emerging technologies into their practices. More specifically, it investigates, through the elaboration of a theoretical learning framework, how terrorist groups can adopt the practices…

Mechanobiology is a major area in biology, however, mechanics is currently a missing element in drug development pipelines. This has led to a high cost for the society. Mechanotoxicity of drugs often appears as a long-term side effect of drugs, and has led to removal of drugs from the market. Furthermore,…

This thesis is a collection of experimental attempts to enhance photoluminescence of fluorescent molecules and quantum dots with single gold nanorods (GNRs) and relevant applications.

Leiden University organizes a course on quantum mechanics for high school Physics teachers. As the curriculum gains a new quantum component, the university enables teachers to give the best possible guidance to their students.

The most famous cat in science is Schrödinger's cat, the quantum mechanical mammal, which can exist in a superposition, a state that is alive as well as dead. The moment you look at it, one of both options is chosen. Leiden University physicists simulated an experiment to catch this mysterious moment…

The development of new environmentally sound technologies is seen as a key route towards achieving sustainability.

An examination of academic organization at the forefront of the biotechnology revolution

The demand for neodymium-iron-boron (NdFeB) magnets is rapidly growing, while the neodymium supply chain is under pressure. Recycling can alleviate these issues. This thesis investigates the potential for deploying novel magnet recycling technologies and their environmental consequences.

Language learners in higher education increasingly conduct out-of-class self-directed learning facilitated by mobile technology. This project aims to explore how university students use mobile technology for their self-directed language learning and investigate factors that influence their self-directed…

In a recent Physics World podcast, PhD candidate Felix Frohnert from Leiden University explains how his team uncovered hidden connections in scientific literature by using machine learning routines. With this information, it’s possible to predict promising new research ideas in quantum physics. Listen…

Explores the relationship between technics and humanity, tracing the emergence of a bio-technical conception of existence in contemporary continental philosophy. Suny Press

How digital technologies affect the way we conceive of the self and its relation to the world, considered through the lens of media art practices.

The Case of the Painted Plaster

Physicists have manipulated light with large artificial atoms, so-called quantum dots. Before, this has only been done so well with actual atoms. It is an important step towards light-based quantum technology. Publication on August 30th in Nature Communications.

The facility develops and applies advanced, high-throughput methods for genomic research.

Healthcare Information Systems (HIS) are essential for modern healthcare delivery, yet their development faces significant challenges including heterogeneous data formats, regulatory compliance, and the growing demand for AI-driven decision support.

While self-driving cars and autonomous weapon systems have received a great deal of attention in media and research, the general requirements of ethical life in today’s digitalizing reality have not been made sufficiently visible and evaluable.

How can the concept of Critical Making be expanded into a general approach that ties the critical methodology of artistic research, and the established concepts of artistic autonomy, together with contemporary creative-technological development?

Rare-earth materials are prime candidates for storing quantum information, because the undesirable interaction with their environment is extremely weak. Consequently however, this lack of interaction implies a very small response to light, making it hard to read and write data. Leiden physicists have…
