Anyone who follows the Faculty of Archaeology on social media must have noticed that something changed in September. Videos on research projects, interviews with staff and students, and embracing memes: the content has become more varied and engaging. We speak with students Grace Alonzo and Thomas Prins,…

In July 2004, a cooperation started between the Faculty of Archaeology and the Museo del Hombre Dominicano and the (University College London, England, Dr. José Oliver), to explore the possibilities to jointly undertake archaeological investigations in the Dominican Republic.

Fieldwork is a crucial part of the learning process for students in the Faculty of Archaeology. This includes both fieldwork aimed at collecting archaeological data and materials as well as fieldwork for heritage studies. The Faculty has established a specific centre of expertise to further shape these…

The field and the classroom invites ethnographers to engage with critical and engaged pedagogies. Breaking down the barriers between fieldsite and lecture hall, this research cluster aims to interrogate the structures and values that shape anthropological and sociological education today.

This thesis is about cosmological inflation and its relation to observations.

Artin L-functions associated to continuous representations of the absolute Galois group G_K of a global field K capture a lot of information about G_K as well as arithmetic properties of K.

Our cantilevers have a low intrinsic damping rate: this enables us to measure with low noise, since damping is proportionate to noise. However, when the magnet is close to the surface of a sample we want to study, we measure a much higher effective damping rate. This is caused by magnetic interaction…

Since the adoption of agriculture people have cultivated fields. The project concerns all kinds of aspects related to raising crops.

The thesis describes terrestrial field trials aimed to detect side-effects of pesticides within the framework of pesticide registration procedures. Field trials were developed using vascular plants Brassica napus and Poa annua, caterpillars Pieris brassicae and effects on decomposition were studied…

In this thesis, we show that we can use Shimura’s CM theory to explicitly compute the Hilbert class field of any primitive quartic CM field.

The insights leading to the present project firstly manifested themselves in 2008, when I worked with field recordings on the basis of relatively well-established notions in music composition studies, such as ‘musical material’ and écriture. With hindsight, I understand the outcomes of those first experiments…

In this work we describe three methods to improve the performance of Quantum Field Theory calculations.

In his groundbreaking Imagined Communities, first published in 1983, Benedict Anderson argued that members of a community experience a

This volume is the outcome of collaborative European research among archaeologists, archaeobotanists, ethnographers, historians and agronomists, and frequently used experiments in archaeology.

This thesis describes the implementation and on-sky demonstration of high-resolution integral-field spectroscopy for extreme adaptive optics systems that are used to find and characterize exoplanets.

Make more fluid: In condensed matter systems, electrons can acquire unusual properties from their interaction with the atomic lattice.

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

The redox-conversion reaction of metal-disulfide and metal-thiolate complexes are important, as they may shed light on electron-transfer reactions that often occur in Nature.

On the largest scale, the Universe resembles a cosmic spiderweb. Most galaxies coexist in small groups within the threads of this web. At the nodes of the threads are enormous groups of galaxies forming the largest structures in the universe still held together by gravity: clusters of galaxies.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

How do humans control their thoughts and actions, and what can high-field brain scanning reveal about the underlying processes?

Leiden University Library and related museum holdings in Leiden contain a body of materials showing the unique role of Dutch-Japanese trade relations as a node in the history of global flows of knowledge, materials and culture during the early modern period.
