de Broglie wave phase shifts induced by surfaces closer than 25 nm
de Broglie wave phase shifts induced by surfaces closer than 25 nm
Four atom optics experiments that each serve to measure atom-surface interactions near nanofabricated gratings are presented here. In these experiments atoms in a beam travel within 25 nm of a material grating bar, and the analysis incorporates phase shifts for the atomic de Broglie waves due to interactions betwen Na …
