The research program of the QO group has three leading themes: Optical Physics, Quantum Optics, and Photon-Matter Interactions. We work mostly at the boundaries between these themes with entanglement as a bridging and binding agent.

Metal complexes and 2D materials like graphene were combined to produce structures that can function as sensors.

This book provides the answers, presenting clear insights into the current state of affairs and exploring future prospects.

Presents a novel philosophical account of psychedelic experiences, arguing that they can be induced by means other than psychedelics — such as meditation and yoga.

The main goal of the research described in this thesis was the development of new photoactivated chemotherapy (PACT) ruthenium(II) complexes bearing a non-toxic photolabile ligand.

For thousands of years bloodlines have been held as virtually unassailable credentials for leadership, with supreme political power perceived as a family affair across the globe and throughout history. At the heart of royal dynasties, kings were inflated to superhuman proportions, yet their status came…

The CMCB brings together a diverse range of unique expertise in microbial cell biology. Members of the CMCB investigate both model and non-model organisms, bacteria and archaea, pathogens and non-pathogens.

Multi-Angle Dynamic Light Scattering (MADLS) is a technique that is used to determine properties of particles in suspension. The measurements give the hydrodynamic size distribution of individual particles as well as particle clusters, and assists in the interpretation of the stability of the particles…

When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.

Sebastian Diessner, Assistant Professor at the Institute of Public Administration, focuses on the role of the European Central Bank in a critical phase toward a new presidency and its approach to monetary policy by looking at both financial market and survey data.

A remarkable population of short period transiting rocky exoplanets with equilibrium temperatures on the order of 2,000 K has recently been discovered.

The quantum nature of matter and light has grown into a broad and fruitful research field for theorists and experimentalists alike. It combines foundational research with toward applications, the most well known of which is the quantum computer.

We highly value the precision and clarity brought by the use of analytic tools combined with creative and non-standard attempts to shine new light on the big questions of theoretical philosophy.

Commercial enterprises who want to make use of the expertise and facilities are referred to LAB , the commercial unit responsible for specialized laboratory work.

Plants could be regarded as small chemical factories, which produce chemical substances via photosynthesis. If we can imitate photosynthesis in an artificial system, we can make clean fuels and materials out of sunlight and CO2. Huub de Groot is very close to designing a system of this kind.

On 5 September 2017, Alessandro Tonutti defended his PhD dissertation

The aim of our research program is to better understand the etiology and course of mood, anxiety and stress-related disorders, such as depression and posttraumatic stress disorder (PTSD). We investigate both the transdiagnostic mechanisms underlying these disorders and work on improving the treatments…

To strenghten ties with the public, press, other academics and wider society, LION employs an outreach officer.

Artificial photosynthesis has recognised potential to produce green and sustainable fuels from earth-abundant resources such as water, carbon dioxide (CO2), and sunlight.

The High-Tech Innovation specialisation consists of a 60 EC track alongside the students' core MSc programme: Astronomy, Chemistry, Computer Science, Mathematics and Physics.

Although many studies have addressed democracy in education around the world, so far research on democratic education in the context of communist society has been scarce. In the current study, we aim to clarify the concept of democratic value and its manifestation in Vietnam’s schools. In addition,…

The Supplementa series of BABESCH is designed as a platform for thematic publications, in juxtaposition to the annual and varied mix of contributions offered by the journal itself. The thematic publications will include proceedings of colloquia, collections of particular studies by one or more authors,…

This project aims at providing a broad perspective of the state of Science Technology and Innovation (STI) in Africa with a focus on global funding flows, in order to inform research funders in the continent, in particular those participating in the Science Granting Councils Initiative (SGCI). The project…

This study seeks to identify suitable local environments conditions for the objects displayed at the Jordanian museums using the proper methods in order to contribute to the stabilization of these objects.

Clinical psychology is a discipline concerned with the application of psychological science to the assessment and treatment of mental disorders.

Visualising structures of life

Collaboration is increasingly common among teachers in schools. As such, teacher education should prepare prospective teachers to effectively interact with other teachers in different types of communities or groups.

Death’s Social and Material Meaning beyond the Human is edited by Jesse D. Peterson, Natashe Lemos Dekker and Philip R. Olson

This thesis consists of two subjects, that are both a consequence of radiation pressure.

World History — a Genealogy charts the history of the discipline through twenty-five in-depth conversations with historians whose work has shaped the field of world history in fundamental ways.

This article is aimed to shed light on the Swahili-‘Ajam ī manuscripts, focusing on the major Swahili classical genre: the

Knowledge of mental distress and resilience factors over the time span from before to after a stressor is important to be able to leverage the most promising resilience factors and promote mental health at the right time. To shed light on this topic, we designed the RESIST Study, in which we assessed…

We study the dynamics of individual emitters in micro cavities.

The Leiden Islam Blog offers a platform for scholars and publicists from Leiden and beyond to share their research and opinions with a broad audience.

This is a facility where research groups or small companies can apply for space if they need to culture human or animal cells.

Why is there not just one single global law for cases of defamation in cross-border communication mediums such as the internet? Which courts are to be called on in such cases? And is it permissible to hold an intermediary instead of a content provider liable?

The project ‘Between the Holy Land and the World’ proposes a connected history of the Christian communities in the Near East (1900-1948) by means of a study of unpublished Franciscan and Dominican photographic collections.

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.
