Query: First verification of generic fidelity recovery in a dynamical system   We study the time evolution of fidelity in a dynamical many body system,
namely a kicked Ising model, modified to allow for a time reversal invariance
breaking. We find good agreement with the random matrix predictions in the
realm of strong perturbations. In particular for the time-reversal symmetry
breaking case the predicted revival at Heisenberg time is clearly seen.
