Abstract

We report on the measurement of the scattering properties of ultracold 174 Yb bosons in a three-dimensional optical lattice. Site occupancy in an atomic Mott insulator is resolved with high-precision spectroscopy on an ultranarrow, metrological optical clock transition. Scattering lengths and loss rate coefficients for 174 Yb atoms in different collisional channels involving the ground state 1 S 0 and the metastable 3 P 0 states are derived. These studies set important constraints for future experimental studies of two-electron atoms for quantum-technological applications.

Clock spectroscopy of interacting bosons in deep optical lattices

Raphaël Bouganne, Manel Bosch Aguilera, Alexandre Dareau +3 more

We report on high-resolution optical spectroscopy of interacting bosonic 174 Yb atoms in deep optical lattices with negligible tunneling. We prepare Mott insulator phases with singly- and doubly-occupied isolated sites and probe the atoms using an ultra-narrow 'clock' transition. Atoms in singly-occupied sites undergo long-lived Rabi oscillations. Atoms in doubly-occupied sites are strongly affected by interatomic interactions, and we measure their inelastic decay rates and energy shifts. We deduce from these measurements all relevant collisional parameters involving both clock states, in particular the intra- and inter-state scattering lengths.

Cold-collision-shift cancellation and inelastic scattering in a Yb optical lattice clock

Andrew D. Ludlow, N. Lemke, Jeff A. Sherman +4 more

Recently, $p$-wave cold collisions were shown to dominate the density-dependent shift of the clock transition frequency in a ${}^{171}$Yb optical lattice clock. Here we demonstrate that by operating such a system at the proper excitation fraction, the cold-collision shift is canceled below the $5\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}18}$ fractional frequency level. We report inelastic two-body loss rates for ${}^{3}\phantom{\rule{-0.16em}{0ex}}{P}_{0}\phantom{\rule{0.16em}{0ex}}$-${}^{3}\phantom{\rule{-0.16em}{0ex}}{P}_{0}$ and ${}^{1}\phantom{\rule{-0.16em}{0ex}}{S}_{0}\phantom{\rule{0.16em}{0ex}}$-${}^{3}\phantom{\rule{-0.16em}{0ex}}{P}_{0}$ scattering. We also measure interaction shifts in an unpolarized atomic sample. Collision measurements for this spin-1/2 ${}^{171}$Yb system are relevant for high-performance optical clocks as well as strongly interacting systems for quantum information and quantum simulation applications.

Collisional Losses, Decoherence, and Frequency Shifts in Optical Lattice Clocks with Bosons

Christian Lisdat, J. S. Raaj Vellore Winfred, Thomas Middelmann +2 more

We have quantified collisional losses, decoherence and the collision shift in a one-dimensional optical lattice clock on the highly forbidden transition (1)S(0)-(3)P(0) at 698 nm with bosonic (88)Sr. We were able to distinguish two loss channels: inelastic collisions between atoms in the upper and lower clock state and atoms in the upper clock state only. Based on the measured coefficients, we determine the operation parameters at which a 1D-lattice clock with (88)Sr shows no degradation due to collisions on the fractional uncertainty level of 10(-16).

Clock-transition spectrum of171Yb atoms in a one-dimensional optical lattice

Ning Chen, Min Zhou, Hai-Qin Chen +8 more

An optical atomic clock with 171 Yb atoms is devised and tested. By using a two-stage Doppler cooling technique, the 171 Yb atoms are cooled down to a temperature of 6±3 μK, which is close to the Doppler limit. Then, the cold 171 Yb atoms are loaded into a one-dimensional optical lattice with a wavelength of 759 nm in the Lamb—Dicke regime. Furthermore, these cold 171 Yb atoms are excited from the ground-state 1 S 0 to the excited-state 3 P 0 by a clock laser with a wavelength of 578 nm. Finally, the 1 S 0 – 3 P 0 clock-transition spectrum of these 171 Yb atoms is obtained by measuring the dependence of the population of the ground-state 1 S 0 upon the clock-laser detuning.

Preparation and Spectroscopy of a Metastable Mott-Insulator State with Attractive Interactions

Manfred J. Mark, Elmar Haller, Katharina Lauber +5 more

We prepare and study a metastable attractive Mott-insulator state formed with bosonic atoms in a three-dimensional optical lattice. Starting from a Mott insulator with Cs atoms at weak repulsive interactions, we use a magnetic Feshbach resonance to tune the interactions to large attractive values and produce a metastable state pinned by attractive interactions with a lifetime on the order of 10 s. We probe the (de)excitation spectrum via lattice modulation spectroscopy, measuring the interaction dependence of two- and three-body bound-state energies. As a result of increased on-site three-body loss we observe resonance broadening and suppression of tunneling processes that produce three-body occupation.
