    "abstract": "A new technique for maintaining high contrast in an atom interferometer is\nused to measure large de Broglie wave phase shifts. Dependence of an\ninteraction induced phase on the atoms\u0027 velocity is compensated by applying an\nengineered \\emph{counter phase}. The counter phase is equivalent to a rotation\nand precisely determined by a frequency, and can be used to measure phase\nshifts due to interactions of unknown strength. Phase shifts of 150 radians (5\ntimes larger than previously possible) have now been measured in an atom beam\ninterferometer and we suggest that this technique can enable comparisons of\natomic polarizability with precision of one part in 10,000.",
