What is it about?
Previous studies have demonstrated the feasibility of neutron interference using split-crystal interferometers. We numerically investigate the contributions to the neutron phase from geometrical aberrations and dynamical diffraction, and we explore an alternative geometry where the interferometer is operated vertically.

Why is it important?
This is crucial because to effectively utilize crystal neutron interferometry, one must comprehend the impacts of gravity, Coriolis forces, crystal transmission and reflection, and geometric imperfections on the neutron wave function.
Perspectives
We demonstrated that operating a split-crystal interferometer vertically allows us to measure the gravity-induced phase difference using a feedback loop to keep the crystals aligned. This approach eliminates any dynamic contributions to the measurement.
