The - magnetic quadrupole transition in neutral strontium
J. Trautmann, D. Yankelev, V. Klüsener +3
We present a detailed investigation of the ultranarrow magnetic-quadrupole - transition in neutral strontium and show how it can be made accessi…
Fast and dense magneto-optical traps for Strontium
S. Snigirev, A. J. Park, A. Heinz +2
We improve the efficiency of sawtooth-wave-adiabatic-passage (SWAP) cooling for strontium atoms in three dimensions and combine it with standard narrow-line laser cooling. With thi…
Low-noise optical lattices for ultracold Li
S. Blatt, A. Mazurenko, M. F. Parsons +3
We demonstrate stable, long-term trapping of fermionic Li atoms in an optical lattice with MHz trap frequencies for use in a quantum gas microscope. Adiabatic release from the…
Optical Feshbach resonances: Field-dressed theory and comparison with experiments
T. L. Nicholson, S. Blatt, B. J. Bloom +4
Optical Feshbach resonances (OFRs) have generated significant experimental interest in recent years. These resonances are promising for many-body physics experiments, yet the pract…
Systematic study of Optical Feshbach Resonances in an ideal gas
S. Blatt, T. L. Nicholson, B. J. Bloom +4
Using a narrow intercombination line in alkaline earth atoms to mitigate large inelastic losses, we explore the Optical Feshbach Resonance (OFR) effect in an ultracold gas of boson…
Rabi Spectroscopy and Excitation Inhomogeneity in a 1D Optical Lattice Clock
S. Blatt, J. W. Thomsen, G. K. Campbell +5
We investigate the influence of atomic motion on precision Rabi spectroscopy of ultracold fermionic atoms confined in a deep, one dimensional (1D) optical lattice. We analyze the s…
Probing Interactions between Ultracold Fermions
G. K. Campbell, M. M. Boyd, J. W. Thomsen +12
At ultracold temperatures, the Pauli exclusion principle suppresses collisions between identical fermions. This has motivated the development of atomic clocks using fermionic isoto…
The absolute frequency of the 87Sr optical clock transition
Gretchen K. Campbell, Andrew D. Ludlow, Sebastian Blatt +10
The absolute frequency of the 1S0-3P0 clock transition of 87Sr has been measured to be 429 228 004 229 873.65 (37) Hz using lattice-confined atoms, where the fractional uncertainty…
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…
New Limits on Coupling of Fundamental Constants to Gravity Using Sr Optical Lattice Clocks
S. Blatt, A. D. Ludlow, G. K. Campbell +13
The - clock transition frequency in neutral Sr has been measured relative to the Cs standard by three independent laboratories…
Nuclear Spin Effects in Optical Lattice Clocks
Martin M. Boyd, Tanya Zelevinsky, Andrew D. Ludlow +4
We present a detailed experimental and theoretical study of the effect of nuclear spin on the performance of optical lattice clocks. With a state-mixing theory including spin-orbit…
Sr lattice clock with inaccuracy below 10
Martin M. Boyd, Andrew D. Ludlow, Sebastian Blatt +4
Aided by ultra-high resolution spectroscopy, the overall systematic uncertainty of the - clock resonance for lattice-confined Sr has been characterized…
Dynamic cancellation of ac Stark shift for pulsed EIT/Raman optical lattice clocks
T. Zanon-Willette, A. D. Ludlow, S. Blatt +3
We propose a combination of Electromagnetically Induced Transparency (EIT)/Raman and pulsed spectroscopy techniques to accurately cancel frequency shifts arising from EIT fields in…
Optical atomic coherence at the one-second time scale
Martin M. Boyd, Tanya Zelevinsky, Andrew D. Ludlow +4
Highest resolution laser spectroscopy has generally been limited to single trapped ion systems due to rapid decoherence which plagues neutral atom ensembles. Here, precision spectr…

Andrew D. Ludlow, Martin M. Boyd, T. Zelevinsky +5
With ultracold Sr confined in a magic wavelength optical lattice, we present the most precise study (2.8 Hz statistical uncertainty) to-date of the - optical…
