    "abstract": "We compute the time evolving probability of a Gaussian wave packet to be\nreflected from a rectangular potential barrier which is perturbed by reducing\nits height. A time interval is found during which this probability of\nreflection is enhanced (superarrivals) compared to the unperturbed case. Such a\ntime evolving reflection probability implies that the effect of perturbation\npropagates across the wave packet faster than its group velocity - a curious\nform of nonlocality.",
