Abstract: Quantum backflow is an interference effect in which a matter-wave packet comprised of only plane waves with non-negative momenta exhibits negative probability flux. Here we show that this effect is mathematically equivalent to the appearance… read more here.

Abstract: Within the context of the CL master equation, when a quantum system is initially described by the pure state given by Eq. (15) in the momentum space, the probability for obtaining a negative value in… read more here.

DOI: 10.1142/s0217732318501869
Abstract: It was known that a free, non-relativistic particle in a superposition of positive momenta can, in certain cases, bear a negative probability current — hence termed quantum backflow. Here, it is shown that more variations… read more here.
