Abstract

Bose-Einstein condensates (BECs) in free fall constitute a promising source for space-borne matter-wave interferometry. Indeed, BECs enjoy a slowly expanding wave function [Anderson et. al. 1995, Becker et. al. 2018], display a large spatial coherence [Andrews et. al. 1997] and can be engineered and probed by optical techniques [Denschlag et. al. 2000, Birkl et. al. 1995, Bongs et. al. 2003, Hagley et. al. 1999]. On a sounding rocket, we explore matter-wave fringes of multiple spinor components of a BEC released in free fall employing light-pulses to drive Bragg processes and induce phase imprinting. The prevailing microgravity played a crucial role in the observation of these interferences which not only reveal the spatial coherence of the condensates but also allow us to measure differential forces. Our work establishes matter-wave interferometry in space with future applications in fundamental physics, navigation and Earth observation [Bongs et. al. 2019].
