论文摘要
我们研究了$^6 $ li和$^{53} $ cr fermionic原子的新型混合物中的Ultrocold碰撞，通过损耗光谱法发现了50多个种间feshbach共振。构建完整的耦合通道模型，我们明确地表征了$^{6} $ li-$^{53} $ cr散射属性，并为其他同位素对的预测产生预测。特别是，我们确定了各种Feshbach共振，这些共振可以使弹性$ s $ - 和$ p $ -Wave $^{6} $ li-li-$^{53} $ CR Itsptrotions的受控调整。因此，我们的研究使锂 - 奇异混合物成为最佳选择的平台，用于对高度相关的费米子物质的难以实验的搜索搜索难以捉摸的少数和多体制，并实现了具有具有电力和磁性偶极力矩的新型超低极性分子。
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.
