OtteLab | Crafting matter atom-by-atom
In our group we study matter at the smallest possible scale: the scale of individual atoms. We use scanning tunneling microscopy (STM) to assemble atoms one-by-one into arrangements of our choice, and investigate their collective quantum behavior. This Nature Review gives an excellent overview of our exciting research field.
Our research focuses in particular on magnetic atoms, whose quantum spins combine to display fascinating unexpected physics. Using novel techniques such as electron spin resonance (ESR) STM and ultrafast pump-probe spectroscopy, we aim to observe and control the coherent dynamics of spin arrays. Such spin waves are at the heart of many fundamental phenomena and form the basis for strategies towards quantum information technology.

We are looking for enthusiastic new Postdocs, PhD students and MSc students to join the team! See our Openings page for more information.
We are part of the Department of Quantum Nanoscience at Delft University of Technology. We are grateful for funding from the Kavli Foundation, the European Research Council (Starting Grant) and the Dutch Research Council (Vici Talent Scheme and QuMat Zwaartekracht Progam).
