Noise-resilient Inertial Sensing Using Group II Atom Interferometry
Abstract
Noise-resilient Inertial Sensing Using Group II Atom InterferometryAbstractWhile atom interferometric inertial sensors remain attractive because of their potentialfor high sensitivity and accuracy, developing practical sensors remains challenging in partbecause of the inuence of spurious noise sources. For example, high sensitivity gravity gra-diometers can be a -ected by laser wavelength uctuations, and environmental perturbationssuch as from magnetic ?elds must be carefully shielded. Atom interferometry using groupII atoms could mitigate some of these challenges. The proposed work is to develop a newtype of atom interferometer inertial sensor with superior laser noise immunity and reducedsensitivity to environmental inuences.We will demonstrate an atom interferometric accelerometer and gradiometer by excitinga narrow single-photon transition in strontium atoms, the same transition already used bystate-of-the-art optical atomic clocks. This approach could lead, for example, to gradiometersensitivities of 0:1 E=pHz with relaxed laser and environmental constraints. We will build aproof-of-concept sensor using this new kind of atom optics and characterize its susceptibilityto laser frequency errors.
