Nano-structured Fabry-Pérot resonators in neutron optics & tunneling of neutron wave-particles (Review)

摘要

Correlated to the quantum mechanics wave-particle duality, the optical analogy between electromagnetic waves and cold neutrons manifests itself through several interference phenomena particularly the so called Frustrated Total Reflection i.e., the tunneling process in Fabry-Pérot nano-structured cavities. Prominent resonant situations offered by this configuration allow the attainment of numerous fundamental investigations and surface-interface studies as well as to devise new kinds of neutron optics devices. This review contribution reports such possibilities in addition to the recently observed peculiar Goos-H?nchen longitudinal shift of neutron wave-particles which was predicted by Sir Isaac Newton as early as 1730.
