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…
Cooling and trapping of ultra-cold strontium isotopic mixtures
N. Poli, R. E. Drullinger, G. Ferrari +3
We present the simultaneous cooling and trapping of an isotopic mixture in a magneto-optical trap and we describe the transfer of the mixture into a conservative, far-off resonant…
Long-lived Bloch oscillations with bosonic Sr atoms and application to gravity measurement at micrometer scale
G. Ferrari, N. Poli, F. Sorrentino +1
We report on the observation of Bloch oscillations on the unprecedented time scale of severalseconds. The experiment is carried out with ultra-cold bosonic strontium-88 loaded into…
Cooling of Sr to high phase-space density by laser and sympathetic cooling in isotopic mixtures
G. Ferrari, R. E. Drullinger, N. Poli +2
Based on an experimental study of two-body and three-body collisions in ultracold strontium samples, a novel optical-sympathetic cooling method in isotopic mixtures is demonstrated…
