Bio

Yang is an Assistant Professor of Physics and EECS at the University of Tennessee. Prior to moving to the UTK, he was a postdoctoral associate at the department of physics of the Massachusetts Institute of Technology from 2019-2022. He received his BE degree in Physics & Mathematics from Tsinghua University in Beijing, China in 2015, and Ph.D. in Physics from Max Planck Institute in Dresden, Germany in 2019.  

Research Description

His research interest lies in understanding topological and correlated states, quantum transport, and light-matter interaction in quantum materials and their potential application in wireless communications, data storage, and energy harvesting. He has worked in the areas of antiferromagnetic spintronics, nonlinear optics, moiré semiconductor, electro-catalysis, material informatics, and machine learning. Yang has received several awards, including two overall Winner Awards in the World Supercomputing Contest, the Tschirnhaus Medal from Leibniz Association, and the Otto-Hahn Medal of the Max Planck Society.

After the topological transition, the spin texture for the topological band is projected at the two layers of the MoTe2/WSe2 moirĂ© superlattice. The spin texture forms a real space Skyrmion lattice.
