Ion trap group

The Institute of Precision Measurement Science and Technology Innovation of the Chinese Academy of Sciences (jointly established by the former "Wuhan Institute of Physics and Mathematics" and the former "Institute of Measurement and Geophysics", hereinafter referred to as the "Institute of Precision Measurement") is located in Wuhan, Hubei Province, and is the supporting unit of the "State Key Laboratory of Spectroscopy and Atomic and Molecular Physics" and "Key Laboratory of Atomic Frequency Scale" of the Chinese Academy of Sciences, and is one of the domestic atomic and molecular physics research bases, with important international influence in the field of atomic and molecular physics research. The "Physics of Trapped Ions" research group has long been engaged in the research of ion optical frequency scale and precision spectroscopy of trapped ions. The improved calcium ion optical frequency standard has become the fifth optical frequency standard in the world with uncertainty entering the E-18 level, and the transportable calcium ion light clock of the E-17 order has been successfully developed, which promotes the reference transition of calcium ion optical frequency standard into the new secondary second definition reference, and obtains the internationally most accurate 7Li+ 2s and 2p state fine structure and ultrafine structure splitting measurement results. The research group has one chief scientist of the National Key R&D Program and two national outstanding young people, and currently undertakes a number of national important scientific research projects such as the Ministry of Science and Technology, the Foundation Committee, and the Chinese Academy of Sciences. The research group is now open to recruit high-level talents and postdoctoral fellows in the research fields of atomic and molecular physics, precision measurement physics and radio physics, and warmly welcomes young researchers who love scientific research and have potential to join.

Research interests of the research group: high-precision ion optical frequency scale, electron-less atomic precision spectroscopy, photoclock application.

With a pure academic atmosphere, excellent scientific research platform and generous support treatment, the Institute of Precision Measurement sincerely invites outstanding talents at home and abroad in related research directions to join.
