论文摘要

从理论上讲,在使用非谐波拉曼转变的大量动量转移的情况下,将自旋挤压施加到光原子干涉仪上的可行性,以增强接近Heisenberg极限的加速度计的灵敏度。我们还通过测量eotvos参数来展示如何在双物种原子干涉仪中实现该方案,以精确测试等效原理,并确定最适合该实验的旋转挤压协议。对于在低地球轨道中的太空传播平台,这种方案最终可以以10^(-20)的灵敏度来实现EOTVOS参数的测量。

We theoretically investigate the feasibility of applying spin squeezing to a light pulse atom interferometer in the presence of large momentum transfer using off-resonant Raman transitions, in order to enhance the sensitivity of accelerometry close to the Heisenberg limit. We also show how to implement this scheme in a dual-species atom interferometer for precision test of the equivalence principle by measuring the Eotvos parameter, and identify the spin squeezing protocol that is best suited for such an experiment. For a space borne platform in low earth orbit, such a scheme may eventually enable the measurement of the Eotvos parameter with a sensitivity of the order of 10^(-20).
