Activated Reaction of Polyatomic Molecules on Surfaces Using a High-Dimensional Neural Network Potential: CHD3 + Cu(111)
An accurate description of reactive scattering of molecules on metal surfaces often requires the modeling of energy transfer between the molecule and the surface phonons. Although ab initio molecular dynamics (AIMD) can describe this energy transfer, AIMD is at present untractable for reactions with…

Making sense of an out-of-body experience (OBE), spirituality and mental health
When is (or becomes) an out-of-body experience a R/S experience? (How) do people make sense of their experiences and is this related to mental health? Which motives do people have to (not) communicate their out-of-body experiences with regular and/or alternative caregivers? And what does it tell us…

Strings attached to future high-temperature superconductivity
The behaviour of strongly correlated electron systems, such as high-temperature superconductors, defies explanation in the language of ordinary quantum theory. A seemingly unrelated area of physics, string theory, might give physicists a better understanding of the weird behaviour of these kinds of…

First discovery of high-energy neutrino source
For the first time, scientists have traced back a high-energy neutrino to its source in space. It was produced by a so-called blazar—a supermassive black hole. Researchers from neutrino detector IceCube report this in Science. ‘This is a milestone for neutrino science,’ says physicist Dorothea Samtleben…

Isotopes and the characterization of extrasolar planets
Diverse types of exoplanets such as gas giants on close-in orbits (hot Jupiters) and young massive giants on wide orbits (super Jupiters), with no analogs in the Solar System, pose challenges but also opportunities to our understanding of planet formation and evolution.

How EU farm subsidies favour high-emission animal products
More than 80 percent of the EU’s agricultural subsidies go to the production of animals or animal feed. These products are responsible for 84 percent of the EU’s food-related greenhouse gas emissions. That is revealed in a new study by three Leiden researchers published in Nature Food. ‘If we continue…

Focal-plane wavefront sensors for direct exoplanet imaging: Theory, simulations and on-sky demonstrations
One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…
