“…Atom interferometry [1] has gained prominence due to a number of successful experiments carrying out precise measurements of the gravitational acceleration [2,3,4,5,6], curvature [7,8], gravity gradient [9,10,11,12,13,14,15], rotations [16,17,18,19], gravitational red shifts [20,21,22] as well as fundamental constants like h/m [23,24,25,26] and the Newtonian gravitational constant [27,28,29,30,31,32,33,34]. Atom interferometers are used for testing the Einstein's Equivalence Principle [35,36,37,38].…”
