Probability backflow for correlated quantum states
Arseni Goussev
Abstract
This paper addresses the effect of probability backflow in quantum states with position-momentum correlations. The author constructs correlated states that are accompanied by classically-forbidden probability transfer exceeding its largest possible value for uncorrelated states, the so-called Bracken-Melloy bound
