CONTROLLER FOR AND CONTROLLING NEUTRON ORBITAL ANGULAR MOMENTUM

摘要

An orbital angular momentum (OAM) controller controls OAM of a plurality of neutrons and includes: a substrate; a first surface of the substrate; and a second surface of the substrate disposed opposingly across the substrate from the first surface and including a contoured shape. A process for controlling OAM of neutrons includes: subjecting an OAM controller to a plurality of neutrons; receiving the neutrons at a first surface of the OAM controller; transmitting the neutrons through the OAM controller; and providing a phase shift θ to a wavefunction of neutrons transmitted through the OAM controller according to θ∝T1+T2(φ/2π), wherein T1 is a first thickness of a substrate of the OAM controller, T2 is a second thickness of the substrate, and φ is an azimuthal angle of the substrate.

1. An orbital angular momentum (OAM) controller to control OAM of a plurality of neutrons, the OAM controller comprising:
a substrate; a first surface of the substrate; and a second surface of the substrate disposed opposingly across the substrate from the first surface and comprising a contoured shape that, in combination with the first surface, controls the OAM of the neutrons.
