We report the observation of fringes from a three-grating electron interferometer. Interference fringes have been observed at low energies ranging from 6 to 10?keV. Contrasts of up to 25% are recorded and exceed the maximal contrast of the classical equivalent Moir? deflectometer. This type of interferometer could serve as a separate beam Mach?Zehnder interferometer for low-energy electron interferometry experiments.read more

Matter-wave interferometry: towards antimatter interferometers
TL;DR: In this paper, the limitations and advantages of matter-wave interferometry in different configurations are discussed, and the possibility to apply this approach to scenarios involving antimatter, such as positrons and positronium atoms.

Interaction-Free Measurement with Electrons.
TL;DR: In this paper, a two-grating electron interferometer is constructed in a conventional transmission electron microscope and achieves high contrast in discrete output detectors, tunable alignment with independently movable beam splitters, and scanning capabilities for imaging.

Interferometer for atoms
TL;DR: An atom interferometer made from three 400 nm period transmission gratings with deBroglie wavelength 0.016 nm displayed an interference signal of 70 Hz on a 300 Hz background.
Journal ArticleDOI
An interferometer for atoms.
TL;DR: In this article, a three-grating geometry is used, in which the interfering beams are distinctly separated in both position and momentum, and the interference signal is 70 counts/s, which allows us to determine the phase to 0.1 rad in 1 min.

TL;DR: Good quantitative agreement is found between the experimental observations and microscopic decoherence theory of matter wave interferometer experiments in which C70 molecules lose their quantum behaviour by thermal emission of radiation.
