TL;DR: In this article, the authors used a neutron interferometer to observe the quantum-mechanical phase shift of neutrons caused by their interaction with Earth's gravitational field, which is known as the Earth's magnetic field.
Abstract: We have used a neutron interferometer to observe the quantum-mechanical phase shift of neutrons caused by their interaction with Earth's gravitational field.
TL;DR: In this article, the authors give a measure of particle knowledge in a neutron interferometer that reflects one's ability to predict in which beam a neutron is located, and extend the discussion to partially coherent beams.
TL;DR: In this article, the effect of Earth's rotation on the phase of the neutron wave function was observed using a neutron interferometer of the type first developed by Bonse and Hart for x rays.
Abstract: Using a neutron interferometer of the type first developed by Bonse and Hart for x rays, we have observed the effect of Earth's rotation on the phase of the neutron wave function. This experiment is the quantum mechanical analog of the optical interferometry observations of Michelson, Gale, and Pearson.
TL;DR: In this article, the perfect crystal neutron interferometer was used to test the spinor rotation of spin- 1 2 -systems and showed interference oscillations consistent with the predicted 4π-value.
