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…
Observation of generalized t-J spin dynamics with tunable dipolar interactions
Annette N. Carroll, Henrik Hirzler, Calder Miller +8
Long-range and anisotropic dipolar interactions profoundly modify the dynamics of particles hopping in a periodic lattice potential. We report the realization of a generalized t-J…
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…
Resolved atomic interaction sidebands in an optical clock transition
Michael Bishof, Yige Lin, Matthew D. Swallows +3
We report the observation of resolved atomic interaction sidebands (ISB) in the Sr optical clock transition when atoms at microkelvin temperatures are confined in a two-di…
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…
