Abstract
The experimental manipulation of neutrons with orbital angular momentum (OAM) has paved the way for significant advancements in both fundamental physics and materials science. This study introduces novel applications, including the interference of neutron states with different OAM to enhance Small Angle Neutron Scattering (SANS) interferometry. This technique allows for the extraction of previously inaccessible phase information from diffraction patterns of complex samples. Additionally, we have successfully engineered neutron Airy beams, demonstrating the capability to tailor neutron wavefunctions for unique propagation behaviors. Here, we detail our methodologies for generating and controlling these tailored wavefronts, exploring their potential applications in the study of bulk quantum materials, particularly in the context of skyrmion-based spintronic devices.
