Title: Thermal atom-ion collisions in a K- ${Yb}^{+}$ hybrid system

Abstract

We introduce experimental studies of atom-ion collisions using buffer-gas cooled, trapped ytterbium (Yb⁺) ions immersed in potassium (K) vapor. The range of the collisional temperature is on the order of several hundred kelvin (thermal regime). We have determined various collisional rate coefficients of the Yb⁺ ion per K-atom number density. We find the upper bounds of charge-exchange rate coefficients κ_ce to be (12.7 ± 1.6) × 10^-14 cm³s^-1 for K-¹⁷¹Yb⁺ and (5.3 ± 0.7) × 10^-14 cm³s^-1 for K-¹⁷²Yb⁺. For both isotopes, the spin-destruction rate coefficient κ_sd has an upper bound at (1.46 ± 0.77) × 10^-9 cm³s^-1. The spin-exchange rate coefficient κ_se is measured to be (1.64 ± 0.51) × 10^-9 cm³s^-1. The relatively low charge-exchange rate observed here demonstrates the advantage of using K atoms to sympathetically cool Yb⁺ ions and the relatively high spin-exchange rate may benefit research work in quantum metrology and quantum information processing on an atom-ion platform using K atoms and Yb⁺ ions.

Single-ion properties of the $S_{eff}$ = $\frac{1}{2}$ XY antiferromagnetic pyrochlores $Na A^{'} {Co}_{2} F_{7}$ ( $A^{'} = {Ca}^{2 +}, {Sr}^{2 +}$ )

Journal Article Ross, Kathryn A. ; Brown, J. M. ; Cava, R. J. ; ... - Physical Review B

The antiferromagnetic pyrochlore material NaCaCo₂F₇ is a thermal spin liquid over a broad temperature range (≈140 K down to T_F=2.4 K), in which magnetic correlations between Co²⁺ dipole moments explore a continuous manifold of antiferromagnetic XY states. The thermal spin liquid is interrupted by spin freezing at a temperature that is ~2% of the mean-field interaction strength, leading to short-range static XY clusters with distinctive relaxation dynamics. Here we report the low-energy inelastic neutron scattering response from the related compound NaSrCo₂F₇, confirming that it hosts the same static and dynamic spin correlations as NaCaCo₂F₇. We then present the single-ion levelsmore »« less

Systematics of target and projectile $K$ -x-ray production and radiative electron capture for 20-80-MeV ${Cl}^{q +}$ ions incident on 25-200-μg/ ${cm}^{2}$ Cu targets

Journal Article Tanis, J. A. ; Jacobs, W. W. ; Shafroth, S. M. - Physical Review, A (General Physics)

A systematic investigation of K x-ray production for 20-80 MeV Cl ions in collision with thin self-supporting Cu targets has been conducted. Target and projectile characteristic x rays and radiative electron capture (REC) have been measured as a function of target thickness for incident charge states q < z{sub 1} - 2. At 80 MeV data were also obtained for q = z{sub 1}- 1. Large enhancements in both characteristic x-ray production and REC were observed for q = z{sub 1}- 1. Measured x-ray yields were parametrized vs. target thickness using the model of Betz et al. and least squaresmore »« less

Crystal field excitations from ${Yb}^{3 +}$ ions at defective sites in highly stuffed ${Yb}_{2} {Ti}_{2} O_{7}$

Journal Article Sala, Gabriele ; Maharaj, Dalini D. ; Stone, Matthew B. ; ... - Physical Review B

The pyrochlore magnet Yb₂Ti₂O₇ has been proposed as a quantum spin ice candidate, a spin liquid state expected to display emergent quantum electrodynamics with gauge photons among its elementary excitations. However, Yb₂Ti₂O₇'s ground state is known to be very sensitive to its precise stoichiometry. Powder samples, produced by solid-state synthesis at relatively low temperatures, tend to be stoichiometric, while single crystals grown from the melt tend to display weak “stuffing” wherein ~2% of the Yb³⁺, normally at the A site of the A₂B₂O₇ pyrochlore structure, reside as well at the B site. In these samples Yb³⁺ ions should exist inmore »« less

Search for the $X (5568)$ State Decaying into $B_{s}^{0} π^{\pm}$ in Proton-Proton Collisions at $\sqrt{s} = 8 TeV$

Journal Article Sirunyan, A. M. ; Tumasyan, A. ; Adam, W. ; ... - Physical Review Letters

Here, a search for resonancelike structures in the B⁰_sπ^± invariant mass spectrum is performed using proton-proton collision data collected by the CMS experiment at the LHC at √s = 8 TeV, corresponding to an integrated luminosity of 19.7 fb^–1. The B⁰_s mesons are reconstructed in the decay chain B⁰_s → J/ψΦ, with J/ψ → μ⁺μ_– and Φ → K⁺K^–. The B⁰_sπ^± invariant mass distribution shows no statistically significant peaks for different selection requirements on the reconstructed B⁰_s and π^± candidates. Upper limits are set on the relative production rates of the X(5568) and B⁰_s states times the branching fraction ofmore »« less
