About us Practical matters How to find us prof. dr. S. (Steven) Hoekstra

Research interests

I am an experimental physicist specialised in the development and application of precision measurement techniques to explore the limits of particle physics. In my group we perform experiments with small quantum systems (atoms, ions, molecules) and nanoparticles. The main tools we use to study these particles are lasers, and external electric and magnetic fields. The experiments we do are typically in a very well controlled environment, shielded from all unwanted background. By doing this, the subtle effects of quantum physics become visible, and we can use these atoms, ions, molecules and nanoparticles for a range of exciting experiments. 

More information can be found on my personal webpage.
