论文摘要
我们为二进制量子混合物提供了一个源工程概念，适用于差分精度原子干涉测量法，漂移时间为几秒钟。为了求解混合物的非线性动力学，我们开发了一组缩放方法方程，并验证其有效性将其与耦合的GROSS-PITAEVSKII方程组的系统之一进行对比。这种缩放方法是对单个物种常用的标准方法的概括。讨论了有关种内和种间相互作用方案的有效性范围。我们提出了一个多阶段的非线性原子透镜序列，以同时创建具有超低动力学膨胀能（低于15 pk）的双重合奏。我们的方案具有减轻波前畸变的优势，这是精确原子干涉法中的领先系统效应。
We present a source engineering concept for a binary quantum mixture suitable as input for differential, precision atom interferometry with drift times of several seconds. To solve the non-linear dynamics of the mixture, we develop a set of scaling approach equations and verify their validity contrasting it to the one of a system of coupled Gross-Pitaevskii equations. This scaling approach is a generalization of the standard approach commonly used for single species. Its validity range is discussed with respect to intra- and inter-species interaction regimes. We propose a multi-stage, non-linear atomic lens sequence to simultaneously create dual ensembles with ultra-slow kinetic expansion energies, below 15 pK. Our scheme has the advantage of mitigating wave front aberrations, a leading systematic effect in precision atom interferometry.
