    • Demonstration of a Multipulse Interferometer for Quantum Kicked-Rotor Studies 

      Tonyushkin, Alexey A; Wu, Saijun; Prentiss, Mara (American Physical Society, 2009)
      We implemented a multipulse interferometer scheme that allows us to study a quantum kicked rotor by observing dephasing of momentum coherence. Our study shows that momentum coherence can be nearly perfectly preserved under ...
    • Observation of Saturation of Fidelity Decay with an Atom Interferometer 

      Wu, Saijun; Tonyushkin, Alexey A; Prentiss, Mara (American Physical Society, 2009)
      We use an atom interferometer to investigate the dynamics of matter waves in a periodically pulsed optical standing wave: an atom optics realization of the quantum kicked rotor that exhibits chaotic classical dynamics. We ...
    • Straight macroscopic magnetic guide for cold atom interferometer 

      Tonyushkin, Alexey A; Prentiss, Mara (AIP Publishing, 2010)
      We demonstrate a macroscopic magnetic guide for cold atom interferometry, where the magnetic guiding field is generated by a symmetrical array of racetrack coils of copper tape. This system represents a conceptual advance ...
