- Abstract
We present a novel atom interferometer (AIF) geometry in which the differential signal of two co-located interferometers singles out a phase shift proportional to the curvature of the gravitational potential.1 The scale factor depends only on well controlled quantities, namely the photon wave number, the interferometer time and the atomic recoil, which allows the curvature to be accurately inferred from a measured phase. As a case study, we numerically simulate such a co-located gradiometric interferometer in the context of the Hannover very long baseline atom interferometer (VLBAI) facility and prove the robustness of the phase shift in gravitational fields with complex spatial dependence. We define an estimator of the gravitational curvature for non-trivial gravitational fields and calculate the trade-off between signal strength and estimation accuracy with regard to spatial resolution.
