On November 21, theoretical physicist Juan Maldacena gives the Ehrenfest Colloquium. Maldacena is known worldwide as the inventor of AdS/CFT correspondence, which might be key to a theory of quantum gravity. Maldacena is winner of the prestigious Dirac Prize and the Breakthrough Prize in Fundamental…

This thesis investigates the application of deep learning techniques in image analysis across various domains, focusing on four main themes: feature extraction, classification, segmentation, and integration, demonstrating the transformative potential of these technologies.

Majorana particles have been getting bad publicity: a claimed discovery in ultracold nanowires had to be retracted. Now Leiden physicists open up a new door to detecting Majoranas in a different experimental system, the Fu-Kane heterostructure, they announce in Physical Review Letters.

Want to find out how to assemble a human skeleton? Do you know what chemistry can be found around you? And are you easily fooled by fake news? Discover this and more at our Science Fair on 3 October.

Vibrating carbon monoxide molecules adsorbed at the surface of a salt crystal stop moving after a few milliseconds. Scientists now discovered this is dominantly due to the emission of electromagnetic waves. The role of the chemical bond at the surface thereby appears to be less important than previously…

Research at the THEOR group is comprised of the following research themes:

This thesis describes the importance of being able to control the selectivity of potential drug candidates.

Deep learning has revolutionized image processing, enabling remarkable advances in fields from autonomous driving to medical diagnostics.

Leiden University is an international, broad-based university. We distinguish five core domains for our research and teaching activities.

A full overview of THEOR PhD theses.

This thesis aims to improve the detection from ultra-weak single emitter by enhancing their emission properties with plasmonic nanostructures. We exploit the wet-chemically synthesized single crystalline gold nanorods (GNRs) as our basic frameworks in the whole studies, simply because of their unique…

This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.

Heterogeneous catalysis is one of the fundamental processes of modern life, being common in industrial refinery and hydrogen vehicles, all the way to the living cell. The dissociation of H2 on Cu(111) is an important benchmark system for studying heterogeneous catalysis, with a large and varied amount…

Single-molecule spectroscopy has become a powerful method for using organic fluorescent molecules in numerous applications.

The specialisation consists of 120 European Credit Transfer System (EC) points and includes mandatory courses and electives (60 EC) and two research projects (60 EC).

This weeks marks the 10th anniversary of the European Research Council. For the past decade, the council has contributed to many scientific projects all over Europe, including Leiden University. It has funded almost 7,000 researchers, leading to just short of 100,000 scientific articles. A total of…

The Italian physicist Andrea Morello is one of the pioneers of the quantum revolution. He is currently doing research at the University of New South Wales in Sydney, but cherishes his time as a PhD candidate in Leiden.

Leiden scientists and companies receive 1.37 million euros to develop technology for the Einstein Telescope. This underground telescope will measure gravitational waves and must therefore be extremely sensitive. To that end, the consortium conducts research on the damping of vibrations at temperatures…
