1308.1079 (Holger Mueller et al.)

Matter wave interferometry for antimatter gravity measurements    [PDF]

Holger Mueller, Paul Hamilton, Andrey Zhmoginov, Francis Robicheaux, Joel Fajans, Jonathan Wurtele
We describe a light-pulse atom interferometer that is suitable for any species of atom and even for electrons and positrons, in particular for testing the Einstein equivalence principle with antihydrogen. The design obviates the need for resonant lasers through far-off resonant Bragg beam splitters and makes efficient use of scarce atoms by magnetic confinement and atom recycling. We expect to reach an accuracy better than 1% in an initial experiment which can be improved to the part-per million level.
