标题： Representation-free description of light-pulse atom interferometry including non-inertial effects

摘要： 光脉冲原子干涉仪依赖于物质的波性及其与相干激光脉冲的操控。 它们被用于精确的重力测量和惯性传感，以及对基本常数的精确测量。 达到更高的精度需要更长的干涉仪时间，这在微重力环境中自然出现，例如落塔设施、探空火箭和专门的卫星任务，这些任务旨在研究空间中的基础量子物理。 在所有这些情况下，有必要考虑非惯性参考系中干涉仪装置的任意轨迹和不同方向。 在这里，我们提供了一种无需特定表示的原子干涉测量描述，完全基于算子代数，以解决这种情况。 我们展示了如何解析地确定具有任意数量脉冲的干涉仪的相位移以及可见度，包括局部重力加速度、重力梯度、激光旋转和非惯性参考系的影响。 我们的方法方便地统一了以前的结果，并促进了新型干涉仪几何结构的研究。 显示英文摘要

摘要： Light-pulse atom interferometers rely on the wave nature of matter and its manipulation with coherent laser pulses. They are used for precise gravimetry and inertial sensing as well as for accurate measurements of fundamental constants. Reaching higher precision requires longer interferometer times which are naturally encountered in microgravity environments such as drop-tower facilities, sounding rockets and dedicated satellite missions aiming at fundamental quantum physics in space. In all those cases, it is necessary to consider arbitrary trajectories and varying orientations of the interferometer set-up in non-inertial frames of reference. Here we provide a versatile representation-free description of atom interferometry entirely based on operator algebra to address this general situation. We show how to analytically determine the phase shift as well as the visibility of interferometers with an arbitrary number of pulses including the effects of local gravitational accelerations, gravity gradients, the rotation of the lasers and non-inertial frames of reference. Our method conveniently unifies previous results and facilitates the investigation of novel interferometer geometries.
