Atomic Coherence of 2 minutes and Instability of 1.5E-18 at 1 s in a Wannier-Stark Lattice Clock
Kyungtae Kim, Alexander Aeppli, William Warfield +3
We explore the limits of atomic coherence and measurement precision in a 87Sr optical lattice clock. We perform a detailed characterization of key effects, including lattice Raman…
Coherent evolution of superexchange interaction in seconds long optical clock spectroscopy
William R. Milner, Stefan Lannig, Mikhail Mamaev +7
Measurement science now connects strongly with engineering of quantum coherence, many-body states, and entanglement. To scale up the performance of an atomic clock using a degenera…
Collective atomic scattering and motional effects in a dense coherent medium
Sarah L. Bromley, Bihui Zhu, Michael Bishof +9
We investigate collective emission from coherently driven ultracold Sr atoms. We perform two sets of experiments, using a strong and weak transition that are insensitive…
Beyond the Spin Model Approximation for Ramsey Spectroscopy
A. P. Koller, M. Beverland, A. V. Gorshkov +1
Ramsey spectroscopy has become a powerful technique for probing non-equilibrium dynamics of internal (pseudospin) degrees of freedom of interacting systems. In many theoretical tre…
A quantum many-body spin system in an optical lattice clock
M. J. Martin, M. Bishof, M. D. Swallows +6
Strongly interacting quantum many-body systems are fundamentally compelling and ubiquitous in science. However, their complexity generally prevents exact solutions of their dynamic…
Cold collision shift cancelation and inelastic scattering in a Yb optical lattice clock
A. D. Ludlow, N. D. Lemke, J. A. Sherman +4
Recently, p-wave cold collisions were shown to dominate the density-dependent shift of the clock transition frequency in a 171Yb optical lattice clock. Here we demonstrate that by…
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…
Many-body treatment of the collisional frequency shift in fermionic atoms
A. M. Rey, A. V. Gorshkov, C. Rubbo
Recent clock experiments have measured density-dependent frequency shifts in polarized fermionic alkaline-earth atoms using 1S0-3P0 Rabi spectroscopy. Here we provide a first-princ…
