Spinoza prize for Jan Zaanen
Jan Zaanen, Professor in Theoretical Physics of condensed material, has been awarded a Spinoza prize. His pioneering ideas about the collective behaviour of quantum particles and high temperature superconductivity have often given him the reputation of being something of a rebel.

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…

Koenraad Schalm Group - String Theory and Experiment
Truth is stranger than fiction. In 1997 Juan Maldaceña discovered a remarkable dictionary that translates equation for equation the physics of black holes in string theory into the more conventional physics of quantum mechanics of interacting particles. The remarkable possibility exists that…

Graphene is a thoroughbred that has to be tamed
Electrons in graphene behave like light particles; they have no mass and can penetrate everything: very useful if you dream about nano-electronics. But you do have to channel them. Carlo Beenakker will be researching how. He has been awarded an ERC Advanced Grant of 1.5 million euro to carry out this…

Exploring the Universe
Astronomers want to understand the Universe, from the Big Bang to the present day, and what the future will hold. In Leiden they focus on two key questions: ‘How did stars and planets originate’ and ‘How were galaxies and black holes formed in the young Universe?’ A new generation of telescopes – just…

Searching for an explanation for remarkable behaviour of ice on Earth
If you replace the standard hydrogen atoms in ice with a heavier variant, something odd happens. The volume occupied by the molecules increases by 0.1 per cent. Leiden chemist Jörg Meyer and his colleagues have created a theoretical model that describes this behaviour. Their research appeared on the…

Setup: Static Magnetic Field with Low Noise
Our cantilevers have a low intrinsic damping rate: this enables us to measure with low noise, since damping is proportionate to noise. However, when the magnet is close to the surface of a sample we want to study, we measure a much higher effective damping rate. This is caused by magnetic interaction…

Geometric phases in soft materials
Geometric phases lead to a nontrivial interference result when an electron's different quantum mechanical paths choices encircle a magnetic coil in an Aharonov-Bohm experiment.

Chemical bond versus electromagnetic waves
Vibrating carbon monoxide molecules adsorbed at the surface of a salt crystal stop moving after a few milliseconds. Scientists now discovered this is dominantly due to the emission of electromagnetic waves. The role of the chemical bond at the surface thereby appears to be less important than previously…

Vibration Isolation
To be able to measure small forces or small deviations from Boltzmann, the external vibrations at the resonance frequency must be very low. To achieve this, we have developed a very soft vibration isolation system and combine it with several other measures to reduce vibrations in our dilution refrigerators.…
