How is energy really dissipated on the atomic scale when sliding objects slip over a single lattice spacing?

Three major cosmology-focused missions are planned for the next decade: the Euclid space telescope, the Vera C. Rubin Observatory in Chile, and the Nancy Grace Roman Space Telescope.

This thesis investigates how galaxies form and what diversifies the evolutionary histories of galaxies.

How does the vision of problems and solutions from

This was the question Leiden researchers from the Institute of Environmental Sciences CML posed in an article published last week in the journal Resources, Conservation, Recycling

In the spirit of 'unity in diversity', our objective is to promote insight into and appreciation for the wonder that the same physical laws and mathematical concepts apply to the whole of nature, from the largest to the smallest energy and length scales. We strive for the application of abstract theoretical…

Of all the mass in our Universe, 80% is thought to consist of a hypothetical and invisible substance called dark matter (DM).

The Leiden Index of Depression Sensitivity (LEIDS) measures cognitive reactivity (CR) to sadness, an aspect of cognitive vulnerability to depression, conceptually similar to rumination.

This monograph focuses on clustering of objects in high-dimensional data, given the restriction that the objects do not cluster on all the attributes, not even on a single subset of attributes, but often on different subsets of attributes in the data.

Researchers at LIACS are working to devise the computers of tomorrow that will be the backbone of the Cloud and Edge computing paradigms as well as the Internet of Things. In this respect, we are involved in research and development of high performance computing systems, embedded & real-time computing…

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

We focus on natural products research, traditional medicine, ethnobotany and phytochemistry.

The ERC project 'Food citizens?' is a comparative analysis of a growing phenomenon in Europe: collective food procurement, namely networks of people who organize direct food production, distribution, and consumption.

In multi/many-core System-on-Chips (SoCs), the performance is almost linearly scaling with the number of processing elements.

Optical projection tomography (OPT) is a tomographic 3D imaging technique used for specimens in the millimetre scale.

How can artist PhD candidates research their own work? They need to be good at switching from maker to critical observer and their research has to have a solid theoretical basis. This is the premise of Professor Janneke Wesseling. The aesthetic value of their work also has to be up for discussion. Inaugural…

Examining if large scale application of new energy pathways can be constrained by materials and emissions.

Biodiversity enables ecosystems to thrive through the synergy of functional differences among organisms. While human well-being strongly depends on biodiversity-driven ecosystem services, human actions are also at the root of current unprecedented biodiversity declines.

In this thesis we study quantum transport phenomena on the nanometer scale, in two classes of materials: topological insulators with induced superconductivity and graphene superlattices.

The group Theoretical Physics of Life Processes, led by Helmut Schiessel, focuses on the physics of chromatin, the DNA-protein complex that fills the nuclei of eukaryotic cells.

Data theory research on the analysis on the multidimensional data

Imprint of Action is the first large-scale study focussing entirely on sociocultural impact in archaeology and, as such, is explorative in nature; it provides unique insights into the workings of interaction and participation in archaeological events, and openly shares qualitative and quantitative research…

What is the environmental impact, the human health impact and the life cycle and production costs of the lab, pilot and commercial diffusion of nanowires and nanowire-based photovoltaic technologies?

What are the life-cycle environmental impacts and risks to human health and ecosystems of a III-V/Si PV system? How can these be expected to change when the system is deployed at industrial scale? What are the most favourable recycling scenarios?

eLaw colleagues Bart Custers and Helena Ursic have a new publication in the peer-reviewed journal The European Data Protection Law Review.

Tell Sabi Abyad is a major Late Neolithic settlement mound in Northern Syria, belonging to the seventh and early sixth millennium bc. This book presents the results of large-scale fieldwork conducted at the site between 1994 and 1999, under the auspices of the Netherlands National Museum of Antiquities…

We are cosmologists, in other words we use physics to study the Universe, how it started and evolved into the structure that we observe around us.

Can we identify different degrees of economic integration, both within and between regions, on the basis of archaeological proxies?
