Research Field
Because of the interplay among various degrees of freedom, including spin, charge, orbital, symmetry, topology and dimensionality, quantum materials offer an exceptional venue for emerging phenomena and applications, in magnetism, superconductivity, interface engineering and quantum information. Precisely due to this interplay, spin provides a unique view and an effective way to probe and control the fascinating properties and emerging phenomena in quantum materials and ultimately for game changing devices.
We aim to understand the spin phenomena in quantum materials and harness their potential for groundbreaking technologies, with a large effect on cutting-edge research of developing novel quantum materials and thin films, discovering new spintronic phenomena and exploring their applications for quantum information,including topological magnetic materials, two-dimensional materials, spin-triplet superconductors and insulating quantum materials.
