It researches (the possibilities for) the development of a set of principles and best practices for insolvency office holders by comparing multilateral treaties and soft law recommendations and national legislation within Europe.

The deeper understanding of an organism's pathology is important for developing treatments. Over centuries of systematic research, clinical researchers have demonstrated that the more information they acquire about the cellular properties and their organisation in the tissue, the better they can understand…

By growing in a soil plants change the biotic and abiotic properties of the soil in which they grow.

In populations with a seed-bank, individuals can temporarily become dormant and refrain from reproduction until they can become active again. The repository of all dormant individuals in the population is called the seed-bank. Seed-banks are observed in many taxa, including plants, bacteria and other…

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

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

Where does the urge to collect come from? What are the explicit or underlying reasons for gathering large amount of objects?

Statistical considerations guide the design and implementation of the experiments that scientists perform. For instance, in a clinical trial about a the efficacy of a treatment, its effect in a certain minimum amount of patients has to be observed in order to make confident assertions about the efficacy…

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.

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…

De tweejarige masteropleiding Physics wordt aangeboden door het Leids Instituut voor Onderzoek in de Natuurkunde. De opleiding is theoretisch en experimenteel. Er is ruime aandacht voor onderzoekstraining. Ook bieden we veel keuzemogelijkheden en op maat gemaakte, individuele studieprogramma’s.

We use DNA strands to stabilize few-atom silver clusters, which show unique optical and chemical properties. This thesis involves the study of these constructs for various applications.

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

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.

Na het afronden van de bacheloropleiding volgen verreweg de meeste studenten de masteropleiding.

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

In Mykeens Griekenland verschenen vanaf 1600 v. Chr. zeer veel monumentale bouwwerken zoals grote graftombes. Waarom stopte die bouwlust 400 jaar later abrupt? Archeoloog Ann Brysbaert onderzoekt de mogelijke oorzaken dankzij haar ERC Consolidator Grant.

Elektronen in grafeen gedragen zich als lichtdeeltjes; ze hebben geen massa en gaan overal doorheen. Heel handig als je droomt over nano-elektronica. Maar je moet ze wel in goede banen leiden. Carlo Beenakker gaat onderzoeken hoe. Hij kreeg er een ERC Advanced Grant voor van 1,5 miljoen euro.

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

Op 23 juni 2020 verdedigde Santy Kouwagam haar proefschrift 'How lawyers win land conflicts for corporations: Legal Strategy and its influence on the Rule of Law in Indonesia'. Het promotieonderzoek is begeleid door promotoren prof.dr. A.W. Bedner en prof.dr. C.E. von Benda-Beckmann.

N-acylethanolamines (NAEs), including N-arachidonoylethanolamine (anandamide, AEA), N-palmitoylethanolamine (PEA) and N-oleoylethanolamine (OEA), are signaling lipids that play an important role in different physiological process.

OB associations are loose groups of young, massive stars. They constitute the last stage of the massive starformation process, and the context in which new stars are formed.
