Three-path atom interferometry with large momentum separation

Benjamin Plotkin-Swing, Daniel Gochnauer, Katherine E. McAlpine +3

We demonstrate the scale up of a symmetric three-path contrast interferometer to large momentum separation. The observed phase stability at separation of 112 photon recoil momenta…

Bloch Oscillation Phases investigated by Multi-path Stuckelberg Atom Interferometry

Tahiyat Rahman, Anna Wirth-Singh, Andrew Ivanov +3

Atoms undergoing Bloch oscillations (BOs) in an accelerating optical lattice acquire momentum of two photon recoils per BO. This technique provides a large momentum transfer tool f…

Crossed-Beam slowing to enhance narrow-line Ytterbium Magneto-Optic Traps

Benjamin Plotkin-Swing, Anna Wirth, Daniel Gochnauer +3

We demonstrate a method to enhance the atom loading rate of a ytterbium (Yb) magneto-optic trap (MOT) operating on the 556 nm intercombination transit…

Bloch-bands Picture for Light Pulse Atom Diffraction and Interferometry

Daniel Gochnauer, Katherine E. McAlpine, Benjamin Plotkin-Swing +2

We apply a Bloch-bands approach to the analysis of pulsed optical standing wave diffractive elements in optics and interferometry with ultracold atoms. We verify our method by comp…

Interferometry in an Atomic Fountain with Ytterbium Bose-Einstein Condensates

Daniel Gochnauer, Tahiyat Rahman, Anna Wirth-Singh +1

We present enabling experimental tools and atom interferometer implementations in a vertical "fountain" geometry with ytterbium Bose-Einstein condensates. To meet the unique challe…

Excited-Band Bloch Oscillations for Precision Atom Interferometry

Katherine E. McAlpine, Daniel Gochnauer, Subhadeep Gupta

We propose and demonstrate a method to increase the momentum separation between the arms of an atom interferometer and thus its area and measurement precision, by using Bloch oscil…
