Overview​

Recent years have seen a plethora of exciting discoveries that rapidly expand the frontiers of quantum material research. The concept of topology begins to revolutionize our understanding of the emergent properties of matter, such as magnetism and superconductivity – meanwhile, the novel topological materials may form the basis for conceptually new spintronics and energy-harvesting applications. Moreover, emergent phenomena in quantum materials provide an excellent experimental platform to explore emergent quasiparticles that behave like the ever-elusive elementary particles, such as the Weyl fermion and magnetic monopole, thereby merging quantum materials research with cosmology and quantum information. Our research activities focus on designing and synthesizing new materials with macroscopic quantum properties and functionalities that have never been seen before, in both bulk and thin-film form. We then explore their physics with our wide-ranging measurement facilities, combined with theoretical modeling. We aim to lead the innovative quest for new quantum materials that bear a far-reaching impact not only on basic science but also on our everyday life in the future.
