We develop open micro cavities to trap light in small volumes and thereby increase the interaction with intra-cavity emitters. Important aspects in this development are the optical penetration in the mirrors, coupling between optical modes, and scattering and clipping losses.

What is a good data protection law? How does a good data protection law evolve? Is European data protection law a good one? And whether the European data protection applicable to China?

Tuberculosis (TB) is associated with 1.5 million deaths annually. There is a need exists to optimize both current as well as novel antibiotic combination treatment strategies to improve the effectiveness and safety of treatments against TB.

The Dutch Research School for Theoretical Physics (DRSTP) has received excellent ratings from an independent international committee. The DRSTP is a school for PhD training which has grown out of a collaboration between the theoretical physics departments at six Dutch universities—including Leiden—and…

Making the most vibration-free, cryogenic scanning tunneling microscope in the world. A bold mission, but one that PhD candidate Irene Battisti successfully executed together with the Fine Mechanical Department. The new microscope might shed light on how unconventional superconductivity works. PhD Defence…

When you think of physics, do you think only of complicated formulas? You’re not the only one. Therefore, every year, the Leiden Insitute of Physics organises the LION Image Award to show another side of physics: beautiful images about intriguing science. The winner of the 2022 photo competition captured…

In this article, the authors analyse two major factors that deepen informality, namely multipolar geopolitics and the rise of non-state actors.

On 20 March 2019, Tim Dekkers defended his thesis 'Mobility, Control and Technology in Border Areas: Discretion and Decision-making in the Information Age'. The doctoral research was supervised by Prof. dr. J.P. van der Leun en Prof. dr. M.A.H. van der Woude.

With the emergence of online social networks (OSNs), the way people create and share information has changed, which becomes faster and broader than traditional social media.

From educational adventures in the tropics, students building software for real customers, to bacteria that degrade plastics. Scroll through our highlights on educational innovation and the achievements of our students.

The dissociative chemisorption of a molecule on a transition metal surface represents a rate-limiting step in many heterogeneously catalyzed processes, whereby most chemicals are made. In spite of the importance of this reaction, an accurate first principles approach to modeling it does not yet exist.…

On the 24th of June, Martijn Wackers successfully defended a doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Martijn on this achievement!

Lots of efforts are being made to promote open science practices in scholarly publishing. However, information on the openness of scholarly journals is highly fragmented. There are various data sources that provide information on specific aspects of openness, but there is hardly any integration of these…

By detecting the tiny forces between a micrometer sized magnet and the spins of hydrogen nuclei, we can do MRI with a volume resolution that is approximately 12 orders of magnitude better than a conventional MRI.  

The Physics and Education master specialisation gives you the opportunity to combine physics research with an excellent education in becoming a physics teacher.

The Physics and SCS master specialisation gives you the opportunity to combine Physics research with different aspects of science communication.

World-class research is integral part of the master’s education. You obtain a Physics degree from an institute with an international reputation. Research in this programme is fundamental and curiosity-driven.

This book examines the critical role of information and knowledge in early modern Europe's global pursuits, exploring challenges in trusting distant information, the development of doubt in intercultural encounters, and the impact of misinformation.

The four possible segments A, T, C and G that link together to form DNA molecules, and with their ordering encode genetic information, are not only different in name, but also in their physical and chemical properties.

In this article for Studies in Conflict & Terrorism, the authors analyse the evolution and interplay of national policies and international diplomacy on cyber terrorism within and across the UNSC’s permanent five members and the UN process on cyber norms (GGE and OEWG).

This article explores the concept of issue prioritisation within the context of public administration research, focusing on decision-making processes.

As an alternative to the diving board shaped force sensor, we are now developing a magnetically levitated small superconducting particle – or ‘Lead Zeppelin'' – as our mechanical resonator. We explore routes towards detection of gravity between small objects.

Multicopper oxidase, laccase, can efficiently reduce oxygen to water and are mostly used in the enzymatic biofuel cells.

An accurate description of reactive scattering of molecules on metal surfaces often requires the modeling of energy transfer between the molecule and the surface phonons. Although ab initio molecular dynamics (AIMD) can describe this energy transfer, AIMD is at present untractable for reactions with…

Joanna Krenz defended her thesis on 15 May 2018.

In this thesis, we describe the latest advances in SQUID-detected Magnetic Resonance Force Microscopy (MRFM).

The research group Science Communication and Society aims to understand how science communication works to improve the interaction between science and society. Central themes are ‘Bridging the gap between experts and the general public’ and ‘Evaluating Science Communication’.

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…

The dissociative chemisorption of methane on metal surfaces is of fundamental and practical interest, being a rate-limiting step in the steam reforming process. The reaction is best modeled with quantum dynamics calculations, but these are currently not guaranteed to produce accurate results because…
