Quantum superarrivals: Bohr's wave-particle duality revisted

Abstract

The phenomenon of quantum superarrivals is manifested in the probabilities for Schrodinger wave packets scattered from perturbed potential barriers. We argue that both classical wave-like and classical particle-like properties can be exhibited in the same gedanken experimental setup for obtaining superarrivals through Schrodinger dynamics. An interesting question regarding the tenet of mutual exclusiveness, a la Bohr, of these two properties is raised in the context of this phenomenon.
