Atom Interferometry  

In General > s.a. atomic physics; molecular physics; neutrons.
* Idea: Interference between atoms in a double-slit experiment was first seen in 1991; It can now can be used as a gyroscope using the Sagnac effect, or to measure accelerations (with a precision of the order of 10−9 g); A space version has been proposed as a way to improve tests of violations of the equivalence principle, as a high-resolution gradiometer, and to map the gravitomagnetic field (as opposed to integrating it like with Gravity Probe-B); 2008, Used to measure G.
