Exact fixed-angle spinor evolutions via the rotating-frame formalism.
TL;DR: It is shown that an experiment aimed at observing the geometric phase should seek to effect not an adiabatic evolution but a parallel transportation, which is exact, necessarily nonadiabatic, and yields a pure geometric phase.

Dependence of the spinor phase on the orientation of the precession axis
TL;DR: In this article, the dependence of the phase acquired by a spinor during a precession, on the orientation of the precession axis was examined, and possible neutron interferometric experiments for investigating such a dependence were suggested.

Bonse-Hart angular profiles realized for multiply Bragg reflected neutrons.
TL;DR: This experiment constitutes the first realization of the proposal made by Bonse and Hart 35 years ago and opens up avenues for ultrasmall angle neutron scattering studies down to wave vector transfers of 10(-5) A(-1).

A fresh look at diffraction from a nonabsorbing perfect crystal in the Bragg-Laue configuration
TL;DR: The Bragg diffraction from a thick, nonabsorbing perfect crystal theory of dynamical diffraction was studied in this article, where the intensities of two beams, one in the incident and the other in the diffracted direction, exciting the side face of the crystal were characterised.

Geometric phase as a simple closed-form integral
TL;DR: In this paper, the geometric phase measured with reference to a given initial state is derived as an integral of a function of the pure state density operator by invoking the Pancharatnam connection continuously.
