Dr Sake Wang earned his PhD in physics at Southeast University, China, in 2016. Since 2021, he has been an Associate Professor at the Jinling Institute of Technology, China. He was a Visiting Scientist at Tohoku University, Japan, from 2019 to 2021. His current interests focus on theoretical studies of spin and valley transport, as well as valley-optoelectronic devices in two-dimensional materials. He has published 73 papers with more than 4,000 citations. Four of his first-authored and corresponding-authored papers are in the top 1% of ESI highly cited papers. In addition, he has served as an Associate Editor of the Journal of Superconductivity and Novel Magnetism (Springer Publishing) since 2020. Dr Hongyu Tian has been an associate professor at Linyi University, China, since 2023. He completed his PhD in physics at Southeast University, China, in 2013. His research interests mainly focus on the electronic transport properties of two-dimensional systems, including spin and valley-related transport properties, as well as the transport properties of polycrystalline systems. He has published over 50 papers and is PI of the National Natural Science Foundation of China and the Natural Science Foundation of Shandong Province (China).
