In this thesis, we use low-frequency and high-frequency radio observations to address the following questions regarding quasars: is the radio loud/quiet quasar dichotomy real?

The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.

The programme guarantees a thorough experience on the frontline of physics research with a practical training of communicative and computer skills.

Leiden physicists use a new method to measure so-called surface plasmons. Researching these particles could lead to new light-based technology, including faster internet.

Investigating the relations between Tupi Indigenous Knowledge, Museum Collections and the Dutch Colonization of Brazil

Petr Steindl works on quantum dots in microcavities for his PhD research. He manipulates single-photons to create complex structures of light. Applications could include quantum communication and gates for quantum computers.

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

Paul Brakefield, Professor of Evolutionary Biology at the Institute of Biology in Leiden (IBL) has been awarded an ERC Advanced Grant for his research. He will receive 2.5 million euro to develop his research programme over a period of five years.

An enormous number of monumental buildings, such as burial tombs, appeared in Mycenaean Greece after 1600 BC. Why did this urge to build come to an abrupt end 400 years later? Archaeologist Ann Brysbaert investigates the possible causes thanks to her ERC Consolidator Grant.

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.

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.

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…

Jean-Eric Paquet, a Director-General at the European Commission, visited Leiden University on 20 February. He was impressed by the researchers’ drive, the wide range of topics that they research and the strong collaboration with Leiden Bio Science Park.

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

Collaborative and Mediated Authorship in Early Modern English Manuscripts

As a student, university lecturer Berthe Jansen fell under the spell of the Van Manen collection: a collection full of Tibetan writings and objects. A €1.5 million grant now makes it possible to take a really close look at it. 'There is still so much to do and discover.'

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

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…

We study the dynamics of individual emitters in micro cavities.

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.

Is there a sufficiently large market for drug screening and testing in Zebrafish larvae using membrane fusion?

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.

À La Découverte de la Hollande dans les années 1760-1770 : Pierre Famin, Emmanuel de Croÿ-Solre, François-César Le Tellier, Jean-Marie Roland de la Platière, Gabriel-François Coyer. Textes réunis et présentés par Madeleine van Strien-Chardonneau, Paris, Société française d’étude du dix-huitième siècle,…

Kirsten Kanneworff and David Dechant defend their PhD research on quantum physics at Leiden University. Fundamental work with applications in location verification and the financial world.

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:

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…

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.

This thesis covers several aspects of quantum algorithms for near-term quantum computers and its applications to quantum chemistry and material science.

This thesis focuses on amyloid proteins, a class of proteins that convert into amyloid fibrils.

The CIGR brings together a diverse range of unique expertise in genome research rooted in biology, chemistry and physics. Members of the CIGR investigate genome folding and genome transactions. An important aspect is direct as well as long term relevance for medicine. The available expertise extends…

Our group operates at the cross-roads of different disciplines: molecular and cellular microbiology, biochemistry, structural biology and biophysics. The group harbors expertise in a multitude of molecular and cellular approaches including:

This thesis advances automata learning, a key area in computer science, with applications in software verification, biological analysis, and autonomous technologies. It explores three main themes: first, it introduces a passive learning algorithm for generating compact probabilistic models from positive…

The main objective of this thesis was to develop clinically relevant survival models for patients with high-grade soft tissue sarcoma of the extremities, in particular the development and validation of prediction models for use in clinical practice.

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

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.

Detecting nanoscopic objects plays an important role in nanoscience in particular, in the rapidly growing field of nanobiology. The forebear to modern super-resolution microscopy for single molecule investigation, is fluorescence microscopy.

The research groups within the biological, soft and complex systems research area study the physics of a broad range of biological and soft materials. This spans both experimental and theoretical research.

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.

This dissertation focuses on investigating the public communication around quantum science and technology that may affect public engagement.
