摘要翻译:
我们计算了经典气体中剪刀模的频率和阻尼随温度和耦合强度的变化。我们的结果与最近在$^6$Li原子的超冷气体中观察到的剪刀模的主要特征一致。理论和实验之间的比较不涉及拟合参数,因此允许在单一性极限和附近识别非经典效应。

英文摘要:
We calculate the frequency and damping of the scissors mode in a classical gas as a function of temperature and coupling strength. Our results show good agreement with the main features observed in recent measurements of the scissors mode in an ultracold gas of $^6$Li atoms. The comparison between theory and experiment involves no fitting parameters and thus allows an identification of non-classical effects at and near the unitarity limit.
