New generations of materials are constantly being discovered experimentally and predicted theoretically that confound our conventional understanding of how metals, insulators and semi-conductors work. These new materials, classified as Quantum Materials, involve strong-correlations between electrons or magnetic moments, quantum entanglement, topology or frustration, and lead to emergent phenomena like superconductivity, magnetic monopoles or topological insulators – phenomena that are often intriguing for both a fundamental understanding of materials, but also for their vast technological potential.

Researchers in the Quantum Matters group work on topics including high temperature superconductivity, frustrated magnetism and spin-ice, topological insulators, spin-liquids and quantum entanglement and quantum machine learning.
