论文摘要
我们报告了在高度磁性元素ERBIUM和NOSPROSIUM的几种同位素混合物中观察到异核磁性叶状巴赫共振的观察。在许多狭窄的功能中，我们确定了两个高于一个高斯的宽度的共振。在损失率和弹性横截面方面，我们以$^{168} $ er和$^{164} $ dy的混合物来表征其中一种，并观察到与广泛共振相关的通用缩放的温度依赖性。我们的观察结果有望使用这种共振来调整偶极混合物中种间散射特性。我们进一步比较了$^{168} $ er-$^{164} $ dy混合物中狭窄共振的流行率与单个特性情况，并观察到混合物中的共振密度增加。
We report on the observation of heteronuclear magnetic Feshbach resonances in several isotope mixtures of the highly magnetic elements erbium and dysprosium. Among many narrow features, we identify two resonances with a width greater than one Gauss. We characterize one of these resonances, in a mixture of $^{168}$Er and $^{164}$Dy, in terms of loss rates and elastic cross section, and observe a temperature dependence of the on-resonance loss rate suggestive of a universal scaling associated with broad resonances. Our observations hold promise for the use of such a resonance for tuning the interspecies scattering properties in a dipolar mixture. We further compare the prevalence of narrow resonances in an $^{168}$Er-$^{164}$Dy mixture to the single-species case, and observe an increased density of resonances in the mixture.
