  • Precise gravity sensing in dynamic environments is challenging. Here, the long-term stability of a matter-wave gravimeter and high bandwidth of an optical resonator are combined in a compact gravity sensor with high seismic noise suppression.

  • Atom interferometers are highly accurate sensors that use the interference of matter waves to extract knowledge about various quantities, such as the gravitational acceleration. In this work, the authors provide a new interferometer scheme that gives direct access to the gravitational gradient, i.e., higher order moments of the gravitational field.

  • Precision measurements with atom interferometers benefit from reducing the expansion rate of the atomic ensemble within the interferometric beam through matter-wave collimation. Here we demonstrate a collimation method based on time-averaged optical potentials and tunable interactions, realizing expansion energies of a few hundred picokelvin.

  • Matter-wave sensors benefit from high flux cold atomic sources. Here, a time-averaged optical dipole trap is reported that generates Bose-Einstein condensates by fast evaporative cooling and further reduces the expansion by means of an all-optical matter-wave lens.
