Besides physics, the sleep of PhD students also benefits from Vitaly Fedoseev's PhD research. He will receive his doctorate on July 7 for his work on optomechanics within quantum mechanics. And also on a setup that eliminated the need for PhD students to push a button every hour for 72 hours.

This thesis studies the geometry of representation varieties and character stacks. These are spaces parametrizing the representations of a finitely generated group, typically the fundamental group of a compact manifold, into an algebraic group G.

Physicists at Leiden University are developing smart chips that can be programmed with light. These chips are more energy-efficient than traditional chips because they do not require a constant power supply. For this research, they will receive funding in the coming years from the Dutch Research Council…

If computers work on superconducting current, they won’t consume any energy. Leiden physicists have now gained control over a new type of superconducting memory elements. Publication in Nature Communications.

Natural Computing is the field of research that investigates both human-designed computing inspired by nature and computing taking place in nature, i.e., it investigates models and computational techniques inspired by nature and also it investigates phenomena taking place in nature in terms of information…

Quantum technology, statistics and a survey with memes: definitely not your everyday research. Julia Cramer (Leiden Institute of Physics) and Sanne Willems (Institute of Psychology) investigate how people perceive quantum.

On this page you will find an overview of awards and prizes granted to our staff and students in 2023, as well as special appointments at Leiden University and other institutions.

Assessing the risks of engineered nanomaterials (ENMs) solely on the basis of experimental assays is time-consuming, resource intensive, and constrained by ethical considerations (such as the principles of the 3Rs of animal testing). The adoption of computational toxicology in this field is a high p…

The portal for prospective Indonesian Students contains information about the possibilities to study at Leiden University in the Netherlands.

Physicists at the Leiden Institute of Physics (LION) conduct fundamental research into physical phenomena. They are inspired by curiosity and the desire to know more about the world in which we live. This research has always paved the way for new practical applications. These are something that the…
