Quantum Materials

The quantum properties of materials with strongly correlated electrons can give rise to a number of peculiar electronic phases, including superconductivity, unconventional magnetism, or materials with non-trivial topologies. We are interested in developing materials with enhanced transport, optical and magnetic properties with a special focus on understanding the effects of dimensionality on the quantum behavior of solids. Examples include 2D materials displaying quantum spin liquid behavior, and layered Dirac semimetals hosting exotic electronic phases. Ultimately, we aim at harvesting non-trivial band topology for applications in catalysis and beyond.
