Microstructured Quantum Matter Group

Quantum matter describes those materials where unusual electronic correlations or topological defects in the band structure give rise to macroscopic quantum phenomena. We are a junior research group interested in the behavior of quantum materials on the mesoscale, when the sample dimensions become comparable to the intrinsic lengthscale of the material. We develop processes based on Focused Ion Beams to carve microstructures from any starting material. The typical sizes of our structures are in the range of 0.1-100 micrometer, which allows us to tune the sample size by three orders of magnitude across the relevant lengthscales in the material – such as the superconducting penetration depth, vortex lattice constants, or domain sizes of correlated phases such as charge- and spin-density-waves. We are always interested in learning about new materials and welcome proposals for collaborations.

Focused Ion Beam

We explore the potential of the Focused Ion Beam (FIB) as a versatile tool to fabricate microstructures from quantum materials.

High magnetic fields

We collaborate with high magnetic field laboratories to extend our experiments to extreme magnetic fields (up to 45T static and 150T pulsed).

New materials

We are interested in novel materials exhibiting unusual quantum effects, such as high-Tc superconductors, heavy-fermion compounds, topological semi-metals, …
