Giant Berry-phase-Driven X-Ray Beam Translations in Strain-Engineered Semiconductor Crystals.

ABSTRACT: The manipulation of light through its interactions with artificially structured media is a cornerstone of photonics. The rescaling of this concept to the X-ray realm-which will enable us to control X-ray light with the same precision routinely available in the visible/IR range-has so far been hindered by the inherent difficulty of realizing photonic structures with the sub-nanometric resolution dictated by X-ray wavelengths. A promising approach to this challenge is based on the so-called Berry-phase effect, the large beam translations undergone by X-ray photons propagating in a deformed crystal, due to the simultaneous presence of Berry curvatures in real and reciprocal space. In this work, the controlled crystal distortions required to rein in this effect are obtained by pairing the latt
