Photoionization of strontium for trapped-ion quantum information processing
K. Vant, J. Chiaverini, W. Lybarger +1
We report a demonstration of simple and effective loading of strontium ions into a linear radio frequency Paul trap using photoionization. The ionization pathway is 5s2 1S0 -- 5s5p…
Inelastic Collision Rates of Trapped Metastable Hydrogen
David Landhuis, Lia Matos, Stephen C. Moss +5
We report the first detailed decay studies of trapped metastable (2S) hydrogen. By two-photon excitation of ultracold H samples, we have produced clouds of at least 5x10^7 magnetic…
A Numerical Investigation of the Effects of Classical Phase Space Structure on a Quantum System
G Ball, K Vant, N Christensen
We present a detailed numerical study of a chaotic classical system and its quantum counterpart. The system is a special case of a kicked rotor and for certain parameter values pos…
Experimental evidence for the role of cantori as barriers in a quantum system
K. M. D. Vant, G. H. Ball, H. Ammann +1
We investigate the effect of cantori on momentum diffusion in a quantum system. Ultracold caesium atoms are subjected to a specifically designed periodically pulsed standing wave.…
A study of quantum decoherence in a system with Kolmogorov-Arnol'd-Moser tori
G. H. Ball, K. M. D. Vant, H. Ammann +1
We present an experimental and numerical study of the effects of decoherence on a quantum system whose classical analogue has Kolmogorov-Arnol'd-Moser (KAM) tori in its phase space…
