We are a research group at Leiden University. Our lab explores the exotic nature of quantum materials, whose underlying physics seems to have more in common with elementary particles and black holes, than ordinary metals and semiconductors.

​​

We are interested in a wide range quantum materials: From unconventional superconductors and magnets to Mott insulators, and anything in between. One thing that these systems have in common is that their behaviour is governed by large-scale quantum mechanical phenomena. This makes these materials a versatile platform to study the universal problems of modern physics, which cannot be addressed by existing theories (e.g. perturbation).

​

We Investigate such many-body quantum phenomena in carefully-designed nanostructured devices, using Leiden's state-of-the-art nanofabrication facilities and a variety of experimental techniques. These include cryogenic transport measurements and our newly-developed hybrid SQUID-on-tip microscope, which has a unique capacity for nano-resolved imaging of magnetism, currents, dissipation (heating) and topography in parallel.
