What are the new challenges for collective organisations in the logistic sector? On 25 November 2021, Raquel Alquézar Crusellas has visited the ERC group to exchange insights about her new research about collective organisations among delivery riders in Europe.

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

Lecture

Astronomer Koen Kuijken and physicist Tjerk Oosterkamp have each been awarded a major subsidy by NWO. The funding will allow them to construct new research facilities.

LIAS has a School of Asian Studies (SAS), a School of Middle-Eastern Studies (SMES) and a School of Religious Studies (LUCSoR). These designations, and the fields within them, remain foundational to our work. At the same time, the academic community benefits from the presence of cross-regional networks…

This section features online articles by or about the team members of the Food Citizens? project.

The MSc programme Physics offers 5 research-oriented specialisations where you can focus on Theoretical Physics, Quantum Matter and Optics, Biological and Soft Matter, or Cosmology. You can also combine Physics with education, management or science communication.

Introducing the team's work on Comparison

When we read a text, we think we know who wrote it, but in the early modern period, manuscript production was often a collaborative or ‘socialised’ enterprise involving secretaries and scribes who physically wrote what the author dictated.

The studies in this thesis are focused on the physical effects in the flat band materials. The results contain the discovery of strong enhancement of RKKY spin-spin interactions with specific geometric arrangement and dynamical generation of excitonic order parameter with high magnitude.

In this thesis we use Josephson and noise scanning tunneling microscopy for the study of conventional, unconventional (iron-based) and disordered superconductors. On the one hand, Josephson scanning tunneling microscopy allows us to directly visualize the superfluid density with high spatial resolut…

The interest of this thesis lies in spin transport in normal metals and superconducting half-metallic junctions.

We study the dynamics of individual emitters in micro cavities.

In this thesis, time-lapse fluorescent microscopy plays a pivotal role in investigating functional materials within living cells as well as the migratory behaviour of neural progenitor cells.

The van Exter group has an extensive history of prior research in classical and quantum optics. As former part of the group of Han Woerdman, we have studied topics as diverse as:

We increasingly look at international consortia to come up with scientific and technological advances that are needed to address global challenges in areas such as health, the environment and clean energy. However, organising these consortia involves unique challenges. To identify these challenges,…

Psychology Lab on Wheels is possible thanks to the support of our partners.

SALTSWAT -- a project which combines the Spaces for Active Learning & Teaching and the Support wtih Active Teaching -- began in Mid-2019 and is running in pilot until the summer of 2020. The purpose of the project is to find answers to the question of how to systematically accelerate 'active teaching…

Physicist Martin van Exter works with light at nanoscale, at the forefront of nanocomputer research. But as Director of Education he also has a vision for physics teaching. Inaugural lecture 18 November.

The origin and evolution of galaxies are closely linked to many different physical phenomena.

A plasma is an ionized gas with very low electrical resistivity. As such, magnetic field lines are 'frozen in' and move with the fluid. Magnetic field lines that are linked, knotted and tangled, cannot be undone by the fluid motions.
