We show that, contrary to the statements made by many authors, the backflow is not a
nonclassical effect. The backflow is a characteristic feature of solutions of the wave …

New quantum probability flow bounds and associated eigenfunctions are determined
numerically for a free non-relativistic particle, with momentum lying in the range (p 0,∞), for …

Quantum backflow (QB), a counterintuitive interference phenomenon where particles with
positive momentum can propagate backward, is important in applications involving light …

Quantum backflow refers to the counterintuitive fact that the probability can flow in the
direction opposite to the momentum of a quantum particle. This phenomenon has been seen …

Free motion of a quantum particle with the wave function entirely comprised of plane waves
with non-negative momenta may be accompanied by negative probability current, an effect …

The probability density of a quantum particle moving freely within a circular ring can exhibit
local flow patterns inconsistent with its angular momentum, a phenomenon known as …

Universality of motion under gravity, the equivalence principle, is violated for quantum
particles. Here, we study the time it takes for a quantum particle to scatter from the …

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 …

In its original formulation, quantum backflow (QB) is an interference effect that manifests
itself as a negative probability transfer for free-particle states comprised of plane waves with …

Criticisms and a claim in the recent paper Backflow in relativistic wave equations by
Bialynicki–Birula et al 2022 J. Phys. A: Math. Theor. 55 255702 are addressed, and it is …
