论文摘要
我们确定费米混合物中原子的三体结合状态。与真空中三个原子的Efimov光谱相比，我们表明费米海洋系统地变形了Efimov频谱。我们证明，这种效应在统一性附近更为明显，为此我们提供了分析估计。我们表明，在费米海域的存在下，三体结合状态遵守了广义的离散缩放定律。为了对我们的预测进行实验确认，我们提出了YB同位素超速费米混合物的三体结合状态的三个特征，并为结合态和结合能的发作提供了估计值。
We determine the three-body bound states of an atom in a Fermi mixture. Compared to the Efimov spectrum of three atoms in vacuum, we show that the Fermi seas deform the Efimov spectrum systematically. We demonstrate that this effect is more pronounced near unitarity, for which we give an analytical estimate. We show that in the presence of Fermi seas, the three-body bound states obey a generalized discrete scaling law. For an experimental confirmation of our prediction, we propose three signatures of three-body bound states of an ultracold Fermi mixture of Yb isotopes, and provide an estimate for the onset of the bound state and the binding energy.
