thin films for solid-state nuclear clocks
Chuankun Zhang, Lars von der Wense, Jack F. Doyle +11
After nearly fifty years of searching, the vacuum ultraviolet Th nuclear isomeric transition has recently been directly laser excited [1,2] and measured with high spectrosc…
Temperature sensitivity of a Thorium-229 solid-state nuclear clock
Jacob S. Higgins, Tian Ooi, Jack F. Doyle +5
Quantum state-resolved spectroscopy of the low energy thorium-229 nuclear transition was recently achieved. The five allowed transitions within the electric quadrupole structure we…
Frequency ratio of the Th nuclear isomeric transition and the Sr atomic clock
Chuankun Zhang, Tian Ooi, Jacob S. Higgins +9
Optical atomic clocks use electronic energy levels to precisely keep track of time. A clock based on nuclear energy levels promises a next-generation platform for precision…
A clock with systematic uncertainty
Alexander Aeppli, Kyungtae Kim, William Warfield +2
We report an optical lattice clock with a total systematic uncertainty of in fractional frequency units, representing the lowest uncertainty of any clock to d…
