Presently, he is President and Professor of Chemistry, South China University of Technology. He was elected as a member of Chinese Academy of Sciences in 2007.  Later then in 2013, he was elected as a Fellow of The World Academy of Science (TWAS).  Professor Gao is the Vice Chairman of the 9th Committee of China Association for Science and Technology since 2016.  He also serves a number of Editorial Advisory Boards of international peer-reviewed journals, including Chemical Society Reviews (2007-2018), Chemical Science (2010-), Accounts of Chemical Research (2017-).  He is also the Editor-in-Chief of Inorganic Chemistry Frontiers (2013-), and the Associate Editor of National Science Review (2013-).  His research interests are magnetic ordered molecular solids, molecular nanomagnets, and multifunctional molecular materials. Updated in March 2019, Professor Gao [H-index: 87] and his collaborators published more than 460 papers with over 25,000 citations. In 2006, 2011 and 2019, Professor Gao received the prestigious National Natural Science Award (the 2nd Grade) respectively. In 2013, he received Science and Technology Progress Award, Ho Leung Ho Lee Foundation.

Topic: Spin Manipulation in Molecules and Solid

Abstract  Magnetism originates from the spin of the unpaired electrons and their interaction with the unquenched orbital momenta. Thanks to the development of quantum mechanics, the magnetic properties are deeply understood. It has been a cut-edge research field to manipulate the spin behavior of paramagnetic centers from chemical and physical approaches.
For the chemical methods, I will introduce the molecular design and trial for single-ion magnet, which behaves strong axial magnetic anisotropy. The magnetic anisotropy of metallic ions results from the crystal field interaction. We have designed the crystal field of axial symmetry as well as low-coordinated environment to realize chemical spin manipulation on transition metal and rare earth ions[1-3].
With respect to the physical approaches, I will discuss our recent work on coherent controlling the quantum phase of a cat state based on the pulsed electric field in a rare-earth ion solid. We have precisely determined the Stark effect Hamiltonian parameters and the electric-spin coupling is enhanced to be 1.6 Hz / (TꞏVꞏm-1). Combined with microwave, the electric pulses can be used to realize quantum Zeno effect and Deutsche-Josza algorithm[4].
