Noise-Immune Conjugate Large-Area Atom Interferometers
Abstract
We present a pair of simultaneous conjugate Ramsey-Borde atom interferometers (SCI) using large (20 k)-momentum transfer (LMT) beam splitters, where k is the photon momentum. Simultaneous operation allows for common-mode rejection of vibrational noise. This allows us to surpass the enclosed space-time area of previous interferometers with a splitting of 20 k by a factor of 2,500. Among applications, we demonstrate a 3.4 ppb resolution in the fine structure constant and discuss tests of fundamental laws of physics.
