Quantum Materials

Emergent quantum materials can create new paths to advance quantum technology since intriguing and exotic quantum features contained in these materials can lead to new design principles and architectures in quantum logics, e.g. the topological quantum computing based on the Majorana fermions. The QFort center integrates scholars with different expertise – ranging from theoretical prediction to numerical simulation, epitaxial growth, and material characterization – to achieve cutting-edge breakthroughs in quantum materials. Their research interests center around the topological materials, complex oxides, and van der Waals materials. Some of their notable works include the theoretical prediction of the very first topological semimetal, an all-optical control of multiple ferroic orders beyond room temperature in a non-volatile way, and the first realization of a gate-free monolayer pn diode.
