High accuracy measure of atomic polarizability in an optical lattice clock
J. A. Sherman, N. D. Lemke, N. Hinkley +4
Despite being a canonical example of quantum mechanical perturbation theory, as well as one of the earliest observed spectroscopic shifts, the Stark effect contributes the largest…
p-Wave cold collisions in an optical lattice clock
N. D. Lemke, J. von Stecher, J. A. Sherman +3
We study ultracold collisions in fermionic ytterbium by precisely measuring the energy shifts they impart on the atom's internal clock states. Exploiting Fermi statistics, we uncov…
Making optical atomic clocks more stable with level laser stabilization
Y. Y. Jiang, A. D. Ludlow, N. D. Lemke +4
The superb precision of an atomic clock is derived from its stability. Atomic clocks based on optical (rather than microwave) frequencies are attractive because of their potential…
