Abstract

Analogous to the Sagnac effect in light interferometers, the phase shift due to rotations in atom interferometers scales linearly with the enclosed area. We propose a geometry with atoms in free fall utilising symmetric beam splitters and relaunches to enable multiple round trips of the atoms. Consequently, our approach exploits the linear scaling of the phase shift without increasing the size of the sensor head. Based on our estimated parameters, we anticipate a sensitivity of 20 prad/s at 1 s [1]. [1] https://www.nature.com/articles/s41598-021-95334-7
