Research Assistant Professor Institute for Quanfum Science and Engineering

Xiang-Long Yu received Ph.D. from Institute of Solid State Physics, Chinese Academy of Sciences in 2015, and then worked as a postdoctoral fellow in Southern University of Science and Technology. In 2018, he remained as an research assistant professor and was supported by the 2017 National Natural Science Foundation of China-youth program. The main achievements are as follows: he developed first principles combined with tight binding model method and first principles combined with dynamic mean-field theory, which can effectively study real topological and correlated materials; systematically studied group IV two-dimensional topological materials, explain the abnormal evolution characteristics of topological properties, and design spintronics devices by using topological properties of the materials, including four state spin-valley filter and spin twister.
