Excited-band Bloch oscillations for precision atom interferometry
Katherine McAlpine, Daniel Gochnauer, Subhadeep Gupta
Abstract
A method based on Bloch oscillation in an excited band of a pulsed optical standing-wave lattice to increase the momentum separation between the arms of an atom interferometer is proposed and demonstrated experimentally. A significant improvement in measurement precision is achieved.
