Colella, Overhauser and Werner: gravitationally induced neutron interference

What changed

Observed gravitationally induced neutron interference phase using a neutron interferometer.

Scientific scope

The record is the exact three-author 1975 Physical Review Letters experiment. It does not absorb the earlier interferometer development, later rotation and inertia experiments, atom interferometry or a general experimental theory of quantum gravity.
