Our research centers around the physics and applications of quantum materials, with a particular emphasis on the strongly correlated oxides. The research work spans from the synthesis of novel materials and heterostructures, especially utilizing a “materials-by-design” approach to discover material systems (thin films, heterostructures, superlattices, or interfaces) with properties superior to any known, to the studying of the physics of these new emerging properties, and to the development of functional devices exploiting the emergent properties.

Discovery of superconductivity in infinite-layer lanthanide nickelates
[arXiv:2105.13492] The origin of high-Tc superconductivity remains an enigma even though tremendous research effort and progress have been made on cuprate and iron pnictide superconductors. Aiming to mimic the cuprate-like electronic configuration of transition metal,..

Discovery of Whirl – Nature 590, 74 (2021)
In the quest for post-CMOS (complementary metal–oxide–semiconductor) technologies, driven by the need for improved efficiency and performance, topologically protected ferromagnetic ‘whirls’ such as skyrmions and their anti-particles have shown great promise as solitonic information carriers..
