Atom Interferometry with up to 24-Photon-Momentum-Transfer Beam Splitters
Atom Interferometry with up to 24-Photon-Momentum-Transfer Beam Splitters
We present up to 24-photon Bragg diffraction as a beam splitter in light-pulse atom interferometers to achieve the largest splitting in momentum space so far. Relative to the 2-photon processes used in the most sensitive present interferometers, these large momentum transfer beam splitters increase the phase shift 12-fold for Mach-Zehnder …
