These methods enable large momentum transfer interferometers with applications in precision measurement, inertial sensing, and searches for new physics. The dual-lattice dynamics are shown to be adiabatic, similar to Bloch oscillations in a single lattice, and loss mechanisms and systematic effects are discussed. The techniques are implemented experimentally and shown to be phase-stable using a differential measurement between two MachZehnder (MZ) atom interferometers. In a single MZ-interferometer, contrast is observed at up to 240hk momentum splitting, one of the largest coherent momentum splittings achieved to date.
