What is it about?
We present the transfer matrices for the propagation of neutron quantum states, whether pure or mixed, in the presence of gravity and Coriolis forces, in both free space and perfect crystals.

Why is it important?
The formalism developed can be used to study the quantum mechanical phase of neutrons under the influence of Earth’s gravity. Additionally, it provides an alternative perspective on how gravitational and Coriolis forces affect the crystal displacements and tilts experienced by the neutron.
Perspectives
The demonstration that neutron interference can occur using split-crystal interferometers paves the way for extended arm separation, length, and new experiments examining quantum mechanics and gravity.
