Time-domain interferometry (TDI) is a promising method to characterize spatial and temporal correlations at x-ray energies, via the so-called intermediate scattering function and the related dynamical couple correlations. However, so far, it has only been analyzed for classical target systems. Here, we provide a quantum analysis, and suggest a scheme that allows us to access quantum dynamical correlations. We further show how TDI can be used to exclude classical models for the target dynamics, and illustrate our results using a single particle in a double well potential.
时域干涉测量法（TDI）是一种很有前途的方法，可通过所谓的中间散射函数和相关的动态偶联相关来描述 X 射线能量下的空间和时间相关性。然而，到目前为止，它仅被分析用于经典目标系统。在这里，我们提供了一种量子分析，并提出了一种方案，使我们能够获得量子动力学相关性。我们进一步展示了如何使用 TDI 排除目标动力学的经典模型，并使用双势阱中的单个粒子来说明我们的结果。
