    "abstract": "Atom-surface interactions can significantly modify the intensity and phase of\natom de Broglie waves diffracted by a silicon nitride grating. This affects the\noperation of a material grating as a coherent beam splitter. The phase shift\ninduced by diffraction is measured by comparing the relative phases of serveral\ninterfering paths in a Mach-Zehnder Na atom interferometer formed by three\nmaterial gratings. The values of the diffraction phases are consistent with a\nsimple model which includes a van der Waals atom-surface interaction between\nthe Na atoms and the silicon nitride grating bars.",
