First verification of generic fidelity recovery in a dynamical system
arXiv:quant-ph/0602234 · doi:10.1103/PhysRevE.73.066120
Abstract
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.
