论文摘要
这项研究开发了一种新型的实验方法，该方法可以推断出超速费米/玻色原子的杂质之间诱导的相互作用的曲线，通常被称为费米/玻色极性。在这种方法中，我们考虑了一个两体费米/玻色极化物碰撞实验，其中杂质和原子仅相互作用。量子动力学的数值模拟揭示了从几个快照的极性波数据包的测得的两个极性谱之间获得有关两个极性谱之间非本地诱导相互作用的信息的可能性。这是因为每当适用于schrödinger方程的WKB近似时，诱导相互作用的电位都可以通过量子电位很好地平衡。
This study develops a novel experimental method of deducing the profile of interaction induced between impurities in a trapped gas of ultracold Fermi/Bose atoms, which are often referred to as Fermi/Bose polarons. In this method, we consider a two-body Fermi/Bose polaron collision experiment in which impurities and atoms interact only weakly. Numerical simulations of the quantum dynamics reveal the possibility to obtain information regarding the non-local induced interaction between two polarons from a measured profile of the polaron wave packet at several snapshots. This is because the potential of the induced interaction is well balanced by the quantum potential whenever the WKB approximation for the relevant Schrödinger equation is applicable.
