Bloch oscillation phases investigated by multipath Stückelberg atom interferometry

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 for atom optics, but its full exploitation for atom interferometric sensors requires both experimental and theoretical characterization of associated phases. Each BO involves a Landau-Zener crossing with multiple crossings inducing interference known as Stückelberg interference. We develop a multipath Stückelberg interferometer and investigate atomic phase evolution during BOs, up to 100 photon recoil momentum transfer. We compare to numerically calculated single-particle Schrödinger evolution, demonstrate highly coherent BO sequences, and assess phase stability requirements for BO-enhanced precision interferometry in fundamental physics and sensing applications.

Realizing a spatially correlated lattice interferometer

Peng Peng, Dekai Mao, Yi Liang +4 more

Atom interferometers provide a powerful tool for measuring physical constants and affirming fundamental physics with unprecedented precision. The sensitivity of atom interferometers is significantly enhanced by optical lattices and coherent atomic sources. However, their interplay gives rise to additional complexities and intriguing phenomena. Here, we report on realizing a Ramsey-Bord\'e interferometer of coherent matter waves modified by a moving optical lattice in a gravitational field, and explore a resulting multipath interference with tunable coherence. We investigate spatial correlations of atoms both within the lattice and between two arms by interferometry, and observed the emerging multiple interference peaks of the Bose-Einstein condensate with sublattice site resolution. Our findings agree well with simulations, paving the way for high-precision interferometry and exploring rich interferometer phenomena using ultracold atoms.
