Abstract

We perform an analysis of recent experimental measurements and improve the lithium interaction potentials. For $^6$Li a consistent description can be given. We discuss theoretical uncertainties for the position of the wide $^6$Li Feshbach resonance, and we present an analytic scattering model for this resonance, based on the inclusion of a field-dependent virtual open-channel state. We predict new Feshbach resonances for the $^6$Li-$^7$Li system, and their importance for different types of crossover superfluidity models is discussed.

Pairing effects in ultra-cold fermionic lithium

J. McKeever, Leticia Tarruell, Martin Teichmann +6 more

Experiments on ultra-cold fermionic /sup 6/Li confined in a crossed dipole trap. /sup 6/Li possesses Feshbach resonances both in the s-wave and p-wave channels. This features enables the exploration of both s-wave and p-wave pairing mechanisms. We first discuss our observation of Bose-Einstein condensation of /sup 6/Li/sub 2/ molecules in the low-magnetic field wing the s-wave Feshbach located at /spl sim/ 834 G. The molecular BEC offers a good starting point for the exploration of the BEC-BCS (Bardeen-Cooper-Schrieffer) crossover. We have also located p-wave Feshbach resonances in the two lowest hyperfine states of /sup 6/Li. The experimental positions of these resonances are in good agreement with those predicted by coupled channel calculations. We have studied the atom losses close to these resonances and have developed a semi-analytical model capturing our experimental findings.

Characterization of Feshbach resonances in a Li 6 − Li 7 mixture using improved interaction potentials

Jing-Chen Zhang, Paul S. Julienne, Yu Liu

We characterize Feshbach resonances in all isotopologues of the $\mathrm{Li}{-}\mathrm{Li}$ system with improved interaction potentials. Starting from spectroscopically accurate Morse/long-range (MLR) potential-energy curves for the singlet ($X^{1}Σ^{+}$) and triplet ($a^{3}Σ^{+}$) electronic states of $\mathrm{Li}_2$, we apply small phenomenological inner-wall adjustments (following Julienne and Hutson, Phys. Rev. A 89, 052715 (2014), arXiv:1404.2623v3) and fit the resulting potentials to threshold measurements for the $^{6}\mathrm{Li}{-}^{6}\mathrm{Li}$ and $^{7}\mathrm{Li}{-}^{7}\mathrm{Li}$ isotopologues, including binding energies, scattering lengths, and Feshbach resonance positions. Using the optimized potentials in coupled-channels scattering calculations, we predict and characterize s-wave Feshbach resonances in the $^{6}\mathrm{Li}{-}^{7}\mathrm{Li}$ isotopologue. In its lowest-energy hyperfine channel, all resonances are narrow ($\sim 0.01{-}0.1$ G), strongly closed-channel dominated, and predominantly triplet in electronic spin character, in marked contrast to the homonuclear systems. These results provide a foundation for designing Raman optical-transfer pathways to produce ultracold $\mathrm{Li}_2$ molecules in deeply bound rovibrational levels of both the $X^1Σ^{+}$ and $a^3Σ^{+}$ potentials across all three isotopologues.

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.

Exploring Ultracold Collisions in Li6−Cr53 Fermi Mixtures: Feshbach Resonances and Scattering Properties of a Novel Alkali-Transition Metal System

A. Ciamei, Stefano Finelli, A. Trenkwalder +3 more

We investigate ultracold collisions in a novel mixture of ^{6}Li and ^{53}Cr fermionic atoms, discovering more than 50 interspecies Feshbach resonances via loss spectroscopy. Building a full coupled-channel model, we unambiguously characterize the ^{6}Li-^{53}Cr scattering properties and yield predictions for other isotopic pairs. In particular, we identify various Feshbach resonances that enable the controlled tuning of elastic s- and p-wave ^{6}Li-^{53}Cr interactions. Our studies thus make lithium-chromium mixtures emerge as optimally suited platforms for the experimental search of elusive few- and many-body regimes of highly correlated fermionic matter, and for the realization of a new class of ultracold polar molecules possessing both electric and magnetic dipole moments.

Reaching a Fermi-superfluid state near an orbital Feshbach resonance

Junjun Xu, Ren Zhang, Yanting Cheng +3 more

We propose to realize a strongly interacting Fermi superfluid near a narrow Feshbach resonance using the recently discovered ``orbital Feshbach resonance.'' The orbital Feshbach resonance is a type of magnetic field tunable scattering resonance theoretically predicted and experimentally observed recently in the alkaline-earth-metal-like $^{173}\mathrm{Yb}$ atom. We first show that the orbital Feshbach resonance is a narrow resonance in energy, while it is hundreds Gauss wide in terms of magnetic field strength, taking the advantage that the magnetic moment difference between the open and closed channels is quite small. Therefore, this is an ideal platform for the experimental realization of a strongly interacting Fermi superfluid with narrow resonance. We further show that the transition temperature for the Fermi superfluid in this system, especially at the BCS side of the resonance, is even higher than that in a wide resonance, which is also due to the narrow character of this resonance. Our results will encourage experimental efforts to realize Fermi superfluid in the alikaline-earth-metal-like $^{173}\mathrm{Yb}$ system, the properties of which will be complementary to extensively studied Fermi superfluids nearby a wide resonance in alkali-metal $^{40}\mathrm{K}$ and $^{6}\mathrm{Li}$ systems.
