Method and device for measuring a local field of gravity, a wave of material on a chip integrated atomic with separation micro - of the atoms.

摘要

The method involves modifying and spatially separating an internal state of atoms to lead the atoms in an intermediate state, where the internal state and another internal state are spatially separated by a distance. The internal states are determined for a determination time during which the atoms accumulate a phase difference to lead the atoms in another intermediate state. The atoms are transferred and placed in a final state. The phase difference is determined by interference of multiple internal states based on measuring the number of atoms found in the internal states. An independent claim is also included for a matter-wave type gravimeter comprising an electronic chip.
