Recently, the team led by Du Lingjie, a leading young scholar at Shishan Laboratory, has made significant progress in quantum physics research.
They carried out measurements on the collective excitations of the fractional quantum Hall effect in high-mobility gallium arsenide quantum wells using cryogenic high-magnetic-field resonant inelastic polarized light scattering technology, and observed collective excitations with graviton characteristics—graviton modes (graviton excitations). This marks the first time such an observation has been made worldwide.
Beijing Time, March 28, 2024 – The top international academic journal Nature published the aforementioned significant achievement online under the title Evidence for chiral graviton modes in fractional quantum Hall liquids. Professor Du Lingjie, a leading young scholar at Shishan Laboratory, is the corresponding author, and Shishan Laboratory is among the affiliated institutions.
Since its founding in 1869, the journal Nature has become one of the world's most renowned multidisciplinary comprehensive scientific and technological journals. The papers published in Nature are read and cited by scholars and scientists from major universities, research institutions, and government departments worldwide, playing a crucial role in advancing the development of science and technology.
Thus, the publication of the research achievement—the first experimental discovery of graviton excitations—in the journal Nature signifies that Professor Du Lingjie, a leading young scholar at Shishan Laboratory, and his team have taken a crucial step in the cutting-edge field of quantum science. It also demonstrates that Shishan Laboratory has made important contributions to attracting more high-end R&D resources to gather in Suzhou.
