Spin-1/2 Optical Lattice Clock
N. D. Lemke, A. D. Ludlow, Z. W. Barber +7
We experimentally investigate an optical clock based on Yb () atoms confined in an optical lattice. We have evaluated all known frequency shifts to the clock transit…
The absolute frequency of the 87Sr optical clock transition
Gretchen K. Campbell, Andrew D. Ludlow, Sebastian Blatt +10
The absolute frequency of the 1S0-3P0 clock transition of 87Sr has been measured to be 429 228 004 229 873.65 (37) Hz using lattice-confined atoms, where the fractional uncertainty…
Frequency evaluation of the doubly forbidden transition in bosonic Yb
N. Poli, Z. W. Barber, N. D. Lemke +11
We report an uncertainty evaluation of an optical lattice clock based on the transition in the bosonic isotope Yb by use of magnetically induced…
Testing the stability of fundamental constants with the 199Hg+ single-ion optical clock
S. Bize, S. A. Diddams, U. Tanaka +10
Over a two-year duration, we have compared the frequency of the 199Hg+ 5d106s 2S 1/2 (F=0)<-> 5d9 6s2 2D 5/2 (F=2) electric-quadrupole transition at 282 nm with the frequency of th…
