NUS Researchers Develop Record-Accurate Lutetium Optical Atomic Clock
Researchers at the National University of Singapore have developed a highly precise optical atomic clock using lutetium, achieving a record low uncertainty of 1×10⁻¹⁹. The team created two independent clocks to verify measurements, reaching a comparison uncertainty of 5.7×10⁻¹⁹. This clock is noted for its stability against environmental changes like temperature and magnetic fields. The advancement could enhance precision timekeeping and support research in physics, geophysics, and related fields, with efforts underway to develop a transportable version.
