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…
