Chair of Experimental Solid State Physics - Quantum Materials

An unassuming twist between two two-dimensional carbon crystals has taken the condensed matter physics community by storm. In an entirely novel and simple way it has opened up Pandora’s box of new options to realize interacting topology, superconductivity, magnetism and other many-body states of matter. The main principles that give rise to the plethora of quantum phases in magic angle twisted bilayer graphene (MATBG), namely the ability to use moiré superpotentials to engineer topologically non-trivial flat-bands, can be transferred to a much larger set of van der Waals heterostructures, which has led to the discovery of an even bigger multitude of exotic ground states.

In the Chair of Experimental Solid State Physics - Quantum Materials we use innovative nano-fabrication techniques to create novel designer materials made by vertical stacking and twisting of various 2D materials. The shear infinite number of material combinations and twist-angles allows to engineer exotic quantum systems with an unprecedented level of control and tunability. We study these complex electronic states with a combination of electrical, optical and thermal measurements, and employ these to provide new types of hybrid devices for quantum sensing applications.

    Graphene JJ bolometer in Nature

    Bolometers are devices that measure the power of incident electromagnetic radiation thru the heating of materials, which exhibit a temperature-electric resistance dependence. These instruments are among the most sensitive detectors so far used for infrared radiation detection and are key tools for applications that range from advanced thermal imaging, night… more
