TOPIC: Science Quests with Quantum Atomic Sensors in Space

Abstract
Space provides a unique experimental environment to explore fundamental physics with precision measurement tools of atomic clocks and quantum sensors. With the NASA Cold Atom Laborato-ry (CAL) being launched into space on ISS, an era of atom interferometry in space begins for the most fundamental science quests. In this talk, we will describe two space experiment concepts for fundamental physics measurements. The first experiment is the Quantum Test of Equivalence and Space Time in which dual species interferometers are used to test the universality of free fall to better than one part per 10¹⁵. The second experiment uses multi-loop atom interferometer for search of dark energy Chameleon fields that is capable of detecting the field or ruling out the Chameleon model entirely.
