Quantum Materials

Many-body quantum-mechanical interactions in materials can lead to cooperative phenomena which cannot be predicted from the properties of individual electrons. These so-called quantum materials are at the forefront of condensed matter physics and material science research. They show a large variety of scientifically fascinating and technologically important phenomena, including many forms of magnetism, ferroelectricity and multiferroic behavior, colossal magnetoresistance, Dirac and Majorana fermions, topological order, as well as spin and charge separation. Harnessing these collective phenomena by fabricating devices from quantum materials has the potential to revolutionize computing, telecommunication, and consumer electronics. This includes, in particular, the promise of new devices based on the spin rather than the charge of the electron (spintronics) as well as computers using quantum instead of digital bits (quantum computing). The aim of our interdisciplinary research group is to investigate quantum effects in materials, in particular new quantum phases and emergent phenomena, and to utilize them to develop new devices and applications.
