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…
Field Compensation of Field Frequency Shifts in the Ramsey Spectroscopy of Clock Optical Transitions
A. V. Taichenachev, V. I. Yudin, C. W. Oates +2
We develop the method of Ramsey spectroscopy with the use of an additional field compensating the frequency shifts of clock optical transitions. This method in combination with the…
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…
Optical Lattice Induced Light Shifts in an Yb Atomic Clock
Z. W. Barber, J. E. Stalnaker, N. D. Lemke +6
We present an experimental study of the lattice induced light shifts on the 1S_0-3P_0 optical clock transition (v_clock~518 THz) in neutral ytterbium. The ``magic'' frequency, v_ma…
Sr lattice clock at 1x10^{-16} fractional uncertainty by remote optical evaluation with a Ca clock
A. D. Ludlow, T. Zelevinsky, G. K. Campbell +16
Optical atomic clocks promise timekeeping at the highest precision and accuracy, owing to their high operating frequencies. Rigorous evaluations of these clocks require direct comp…
Direct excitation of the forbidden clock transition in neutral 174Yb atoms confined to an optical lattice
Zeb W. Barber, Chad W. Hoyt, Chris W. Oates +3
We report direct single-laser excitation of the strictly forbidden (6s^2)^1S_0 -(6s6p)^3P_0 clock transition in the even 174Yb isotope confined to a 1D optical lattice. A small (~1…
