Recurrence of fidelity in near integrable systems
R. Sankaranarayanan, Arul Lakshminarayan
Within the framework of simple perturbation theory, recurrence time of quantum fidelity is related to the period of the classical motion. This indicates the possibility of recurren…

Level velocity statistics of hyperbolic chaos
R. Sankaranarayanan
A generalized version of standard map is quantized as a model of quantum chaos. It is shown that, in hyperbolic chaotic regime, second moment of quantum level velocity is $\sim 1/\…
