Decompositions in algebra
We show that Kirchhoff ’s law of conservation holds for non-commutative graph flows if and only if the graph is planar. We generalize the theory of (Euclidean) lattices to infinite dimension and consider the ring of algebraic integers as such a lattice.

Elastisch Leidenfrost-effect voor zachte motoren
Waterdruppels zweven in een hete pan vanwege het zogenoemde Leidenfrost-effect. Nu hebben natuurkundigen een variatie ontdekt: het Elastische Leidenfrost-effect. Het verklaart waarom hydrogel balletjes op een hete plaat rondspringen en hoge piepgeluidjes maken. Publicatie in Nature Physics op 24 jul…

Metamateriaal vouwt zichzelf op
Hoe complexer het voorwerp, des te ingewikkelder het is om op te vouwen. Een ruimtevaartuig heeft al snel vele motortjes nodig om een instrument-arm in elkaar te vouwen en mensen hebben zelfs moeite met een wegenkaart. Natuurkundigen uit Leiden en Amsterdam hebben nu een structuur ontworpen die zichzelf…

Cosmic tomography with weak gravitational lensing
We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.

Nano-scale electronic structure of strongly correlated electron systems
In condensed matter systems electron-electron interactions, negligible in everyday metals, can dramatically alter the electronic behavior of the system. Examples of such altered behavior include high-temperature superconductivity and modulation of the electron density.

The parabolic Anderson model on Galton-Watson trees
The parabolic Anderson model (PAM), which is the Cauchy problem for the heat equation with random potential. The PAM is a mathematical model that describes how mass (i.e. matter or energy) flows in a medium in the presence of a field of sources and sinks.

Probing molecular layers with low-energy electrons
Molecular materials have been a subject of interest in fundamental research and applications for decades, and have been studied as bulk crystals, (thin) films and as individual molecules, due to the large variety in their properties. This dissertation explores pentacene crystals near the two-dimensional…

Low-temperature spectroscopic studies of single molecules in 3-D and on 2-D hosts
Spectroscopic studies on fluorescent single molecules in organic condensed matter does not only provide information about the molecule itself, but also its near environment. By suppression of phonon-induced broadening of spectral lines through cooling to low temperatures, small changes in the spectral…

Eenrichtingsweg voor beweging in nieuw materiaal
Onderzoekers hebben een materiaal ontwikkeld dat ingaat tegen een van de basisprincipes van de natuurkunde. Reguliere materialen die ingedrukt worden, verspreiden de druk gelijkmatig, ongeacht waar die vandaan komt. Het nieuwe materiaal breekt met deze wetmatigheid en dat kan interessant zijn voor toepassingen…
