Theory
Many important topics in computer science, such as the correctness of software, the efficiency of algorithms and the modeling of complicated systems, depend on sound theoretical underpinnings. In the Theory group, we study these fundamental building blocks and develop verification methods to prove system…

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…

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…
