For many system in statistical physics the microcanonical and canonical ensemble are equivalent in the thermodynamic limit, but not for all.

With this thesis the PhD-candidate aims to enrich the body of evidence concerning the relation between stress and health, and the mediating role of (un)conscious perseverative cognitions, which is captured in the extended perseverative cognition hypothesis.

Piecing together the urnfield mortuary process in the Lower-Rhine-Basin, ca. 1300 - 400 BC

This thesis explores Breaking of Ensemble Equivalence (BEE) in random graph models by examining the spectral properties of adjacency matrices. The goal is to identify spectral characteristics that differentiate random graph ensembles, enhancing the understanding of complex network structures and beh…

In this thesis, we have used numerical approaches to study the effects of translational symmetry breaking on strange metallic systems as realised by the holographic duality⁠.

The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.

The Journal of the LUCAS Graduate Conference was founded in 2013 to publish a selection of the best papers presented at the biennial LUCAS Graduate Conference, an international and interdisciplinary humanities conference organized by the Leiden University Centre for the Arts in Society (LUCAS).

This research focuses on the distribution of chemical elements in protoplanetary disks, the birthplaces of planets. These disks form around young stars and contain gas and dust, from which planets grow. Ice plays a crucial role in planet formation, aiding the clumping of dust particles and influencing…

A study of the technology, form, function, and use of pottery from the settlements Uitgeest-Groot Dorregeest and Schagen-Muggenburg 1, Roman Period, North-Holland, the Netherlands

Laboratory, observation and modeling work on the dissociation of polycyclic aromatic hydrocarbons in interstellar environments and the formation of new molecular species through the fragmentation process.

Parents may pass anxiety onto their offspring by exposing them to anxious behaviors in novel situations. Just as the parents’ anxious signals lead to anxiety, parents’ confident signals can ward off anxiety in the offspring. This project is seeking a new way to break anxiety transmission in the family…

Arjan Louwen (MA) will start a PhD research project on the social and ideological aspects of Late Bronze Age and Early Iron Age cremation graves in continental Northwest Europe (1100-500 BC): Breaking and making the ancestors. Making sense of the inconspicuous 99% of urnfield graves.

This thesis seeks to combine two different research topics; Multi-Objective Optimization and Complex Network Analysis.

Striga hermonthica, commonly known as witchweed, infests major cereal crops in Sub-Saharan Africa causing severe yield losses and threatening the livelihood of millions of resource poor farmers.

A collaboration between the IBL and LUMC has resulted in the discovery that the polymerase theta enzyme is essential for the integration of Agrobacterium T-DNA into the genome of plants. The finding means a break-through for the development of more efficient systems for targeted genome modification…

In a promotional video for the SUNRISE initiative, prof. Huub de Groot explains the impact and ideas behind artificial photosynthesis.

In her podcast Tea-Break Time Travel Matilda Siebrecht is joined by fire expert Femke Reidsma, to talk all about how this essential tool was made and used by our ancient human ancestors. How can you recognise an ancient hearth? Why is it so important to study the first use of fire? When was the first…

The research in my group addresses a range of topics related to quantum many-body physics.

In this dissertation several settings in the Online Learning framework are studied. The first chapter serves as an introduction to the relevant settings in Online Learning and in the subsequent chapters new results and insights are given for both full-information and bandit information settings.

On 19 November 2018, the American Bar Association (ABA), Section of Antitrust Law organized a teleconference “Sports and Antitrust: Breaking the Ice”.

Playgrounds often fail to accommodate children with autism, according to researchers Carolien Rieffe and colleagues. They have published an essay offering practical advice on how to make all children feel safe and welcome for Autism Week (Dutch) and World Autism Autism Awareness/ Acceptance Day on 2…

Increasing the efficiency of gene targeting (GT) as a genome editing tool in plants has been an important goal in plant biotechnology.

A History of Modern Political Thought in East Central Europe is a synthetic work, authored by an international team of researchers, covering twenty national cultures and 250 years. It goes beyond the conventional nation-centered narratives and presents a novel vision especially sensitive to the cross-cultural…

From the Big Bang to superconductivity. Many ground-breaking discoveries have been made in Leiden University’s long history.

“To change the world, you do not need everybody. You only need one. So, will you be the one? That’s the question.” Saturday December 3rd, Nobel Laureate Professor Muhammad Yunus gave a special lecture at the Anna van Buerenplein campus of LUC The Hague.

Understanding DNA repair mechanisms is essential for advancing plant biotechnology and crop improvement. This study investigates how double-strand breaks (DSBs), induced by CRISPR/Cas systems, are repaired in the model plant Arabidopsis thaliana, and how these processes influence Agrobacterium tumefaciens…

Systems with local constraints is a new finding in recent researches on complex systems. The heterogeneous spatial interactions and the temporal dependencies among those numerous units make it difficult to describe by traditional statistical physics.

The Leiden Institute of Physics (LION) is the coordinating partner in the Qluster research project, which was awarded a 2,9 million euro FET Open grant by the European Union.
