Development of an Yb optical lattice clock using a fermionic isotope

摘要

We have developed a one-dimensional optical lattice clock with ultracold ~(171)Yb atoms. The absolute frequency of the ~1S_0(F = 1/2) - ~3P_0(F = 1/2) clock transition in ~(171)Yb is determined to be 518 295 836 590 864(28) Hz with respect to the SI second. Details of the experimental setups and atom trapping results are also described.
