Abstract

We report a theoretical study of Feshbach resonances in $^{6}\mathrm{Li}+^{23}\mathrm{Na}$ and $^{7}\mathrm{Li}+^{23}\mathrm{Na}$ mixtures at ultracold temperatures using accurate interaction potentials in a full quantum coupled-channel calculation. Feshbach resonances for $l=0$ in the initial collisional open channel $^{6}\mathrm{Li}(f=1∕2,{m}_{f}=1∕2)+^{23}\mathrm{Na}(f=1,{m}_{f}=1)$ are found to agree with previous measurements, leading to precise values of the singlet and triplet scattering lengths for the $^{6,7}\mathrm{Li}+^{23}\mathrm{Na}$ pairs. We also predict additional Feshbach resonances within experimentally attainable magnetic fields for other collision channels.

Improved characterization of Feshbach resonances and interaction potentials between Na23 and Rb87 atoms

Zhichao Guo, Fan Jia, Bing Zhu +3 more

The ultracold mixture of $^{23}\mathrm{Na}$ and $^{87}\mathrm{Rb}$ atoms has become an important system for investigating physics in Bose-Bose atomic mixtures and for forming ultracold ground-state polar molecules. In this work, we provide an improved characterization of the most commonly used Feshbach resonance near 347.64 G between $^{23}\mathrm{Na}$ and $^{87}\mathrm{Rb}$ in their absolute ground states. We form Feshbach molecules using this resonance and measure their binding energies by dissociating them via magnetic-field modulation. We use the binding energies to refine the singlet and triplet potential-energy curves, using coupled-channel bound-state calculations. We then use coupled-channel scattering calculations on the resulting potentials to produce a high-precision mapping between magnetic field and scattering length. We also observe ten additional $s$-wave Feshbach resonances for $^{23}\mathrm{Na}$ and $^{87}\mathrm{Rb}$ in different combinations of Zeeman sublevels of the $F=1$ hyperfine states. Some of the resonances show two-body inelastic decay due to spin exchange. We compare the resonance properties with coupled-channel scattering calculations that full take account of inelastic properties.

Feshbach resonances in ultracold Rb 85 − Rb 87 and Li 6 − Rb 87 mixtures

Z. Li, S. Singh, Timur V. Tscherbul +1 more

We present an analysis of experimentally accessible magnetic Feshbach resonances in ultracold heteronuclear $^{85}\mathrm{Rb}\text{\ensuremath{-}}^{87}\mathrm{Rb}$ and $^{6}\mathrm{Li}\text{\ensuremath{-}}^{87}\mathrm{Rb}$ mixtures. Using recent experimental measurements of the triplet scattering lengths for $^{6}\mathrm{Li}\text{\ensuremath{-}}^{87}\mathrm{Rb}$ and $^{7}\mathrm{Li}\text{\ensuremath{-}}^{87}\mathrm{Rb}$ mixtures and Feshbach resonances for one combination of atomic states, we create model potential curves and fine-tune them to reproduce the measured resonances and to predict the location of several experimentally relevant resonances in Li-Rb collisions. To model $^{85}\mathrm{Rb}\text{\ensuremath{-}}^{87}\mathrm{Rb}$ collisions, we use accurate ${\mathrm{Rb}}_{2}$ potentials obtained previously from the analysis of experiments on $^{87}\mathrm{Rb}\text{\ensuremath{-}}^{87}\mathrm{Rb}$ collisions. We find resonances that occur at very low magnetic fields, below $10\phantom{\rule{0.3em}{0ex}}\mathrm{G}$, which may be useful for entanglement generation in optical lattices or atom chip magnetic traps.

Feshbach loss spectroscopy in an ultracold Na23−K40 mixture

Minjie Zhu, Huan Yang, Lan Liu +7 more

We perform Feshbach spectroscopy in an ultracold mixture of $^{23}\mathrm{Na}$ and $^{40}\mathrm{K}$ with different spin-state combinations. We observed 24 new interspecies Feshbach resonances at magnetic fields up to 350 G. A full coupled-channel calculation is performed to assign these resonances. Among them, 12 resonances are identified as $d$-wave Feshbach resonances. These $d$-wave Feshbach resonances are about 5 G systematically smaller than the predictions based on the previous model potential. Taking into account these experimental results, we improve the Born-Oppenheimer potentials between Na and K and achieve good agreement between the theory and experiment for all the observed Feshbach resonances.

Feshbach spectroscopy and scattering properties of ultracold Li + Na mixtures

T. Schuster, R. Scelle, A. Trautmann +6 more

We have observed 26 interspecies Feshbach resonances at fields up to 2050 G in ultracold ${}^{6}\text{Li}+{}^{23}\text{Na}$ mixtures for different spin-state combinations. Applying the asymptotic bound-state model to assign the resonances, we found that most resonances have $d$-wave character. This analysis serves as guidance for a coupled-channel calculation, which uses modified interaction potentials to describe the positions of the Feshbach resonances well within the experimental uncertainty and to calculate their widths. The scattering length derived from the improved interaction potentials is experimentally confirmed and deviates from previously reported values in sign and magnitude. We give prospects for ${}^{7}\text{Li}+{}^{23}\text{Na}$ and predict broad Feshbach resonances suitable for tuning.

Contrasting the wide Feshbach resonances in Li6 and Li7

Paul S. Julienne, Jeremy M. Hutson

We compare and contrast the wide Feshbach resonances and the corresponding weakly bound states in the lowest scattering channels of ultracold $^{6}\mathrm{Li}$ and $^{7}\mathrm{Li}$. We use high-precision measurements of binding energies and scattering properties to determine interaction potentials that incorporate non-Born-Oppenheimer terms to account for the failure of mass scaling between $^{6}\mathrm{Li}$ and $^{7}\mathrm{Li}$. Correction terms are needed for both the singlet and the triplet potential curves. The universal formula relating binding energy to scattering length is not accurate for either system. The $^{6}\mathrm{Li}$ resonance is open-channel-dominated and the van der Waals formula of Gao [J. Phys. B 37, 4273 (2004)] gives accurate results for the binding energies across much of the resonance width. The $^{7}\mathrm{Li}$ resonance, by contrast, is weakly closed-channel-dominated and a coupled-channel treatment of the binding energies is required. Plotting the binding energies in universal van der Waals form helps illustrate subtle differences between the experimental results and different theoretical forms near the resonance pole.

Elastic and inelastic collisions of 6Li atoms in magnetic and optical traps

M. Houbiers, Henk T. C. Stoof, W. I. McAlexander +1 more

We use a full coupled-channels method to calculate collisional properties of magnetically or optically trapped ultracold ${}^{6}\mathrm{Li}.$ The magnetic-field dependence of the $s$-wave scattering lengths of several mixtures of hyperfine states are determined, as are the decay rates due to exchange collisions. In one case, we find Feshbach resonances at $B=0.08\mathrm{T}$ and $B=1.98\mathrm{T}.$ We show that the exact coupled-channels calculation is well approximated over the entire range of magnetic fields by a simple analytical calculation.
