We revisit the arguments underlying two well-known arrival-time distributions in quantum
mechanics, viz., the Aharonov–Bohm–Kijowski (ABK) distribution, applicable for freely …

It is shown that a class of exponentially decaying time-of-arrival probability distributions,
suggested by Włodarz [Phys. Rev. A 65, 044103 (2002) 10.1103/PhysRevA. 65.044103] …

Quantum backflow is a counterintuitive phenomenon in which a forward-propagating
quantum particle propagates locally backwards. The actual counter-propagation property …

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 …

This article reviews positive and negative time delays in various processes of classical and
quantum physics. In the beginning, we demonstrate how a time-shifted response of a system …

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 …

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

Consider a scenario where a quantum particle is initially prepared in some bounded region
of space and left to propagate freely. After some time, we verify if the particle has reached …

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 …

We develop a general framework for the construction of probabilities for the time of arrival in
quantum systems. The time of arrival is identified with the time instant when a transition in …
