 On July 17, the winners of the 2023 Xplorer Prize were announced, and Professor HE Song of the Institute of Theoretical Physics, Chinese Academy of Sciences (ITP-CAS) won the prize in the field of "Mathematics and Physics".
The citation for the prize says HE Song “has made significant contributions to the study of scattering amplitudes in Quantum Field Theory (QFT), gravity and string theory, as well as deep connections to mathematics, and he plans to further explore at the intersection of fundamental physics and mathematics”. Scattering amplitudes is the central object in QFT, which bridges theories to experiments. His research starts from amplitudes and spans across QFT, gravity, strings and mathematics. He invented a new theory dubbed CHY formalism for  scattering amplitudes in general theories which opened up a new research direction, and later he discovered new geometries underlying scattering of QFT and string theory. All these works have greatly deepened our understanding of fundamental theories.
HE Song, professor and doctoral supervisor, received his Ph.D. degree from Peking University in 2009, and successively engaged in postdoctoral research at the Max Planck Institute for Gravitational Physics (Potsdam, Germany), Institute for Advanced Study (Princeton, USA) and the Perimeter Institute of Theoretical Physics (Waterloo, Canada), and worked at ITP-CAS since September 2015. HE Song has been very active in the frontier of high-energy theory such as QFT, string theory and quantum gravity. In recent years, he has mainly studied scattering amplitudes and applications to particle physics, gravity and mathematical physics, and is recognized as one of the internationally renowned and leading young scientists in these fields.
Established in 2018, THE XPLORER PRIZE grants a merit-based no-strings-attached award to outstanding scientists under 45 years of age who hold full-time positions in Chinese mainland, Hong Kong SAR, or Macau SAR. It is one of the most generous talent funding programs for young scientists in China.
