Dispersion Compensation for Atom Interferometry
arXiv:quant-ph/0305184 · doi:10.1103/PhysRevLett.92.060405
Abstract
A new technique for maintaining high contrast in an atom interferometer is used to measure large de Broglie wave phase shifts. Dependence of an interaction induced phase on the atoms' velocity is compensated by applying an engineered \emph{counter phase}. The counter phase is equivalent to a rotation and precisely determined by a frequency, and can be used to measure phase shifts due to interactions of unknown strength. Phase shifts of 150 radians (5 times larger than previously possible) have now been measured in an atom beam interferometer and we suggest that this technique can enable comparisons of atomic polarizability with precision of one part in 10,000.
