Quantum backflow current in a ring: Optimal bounds and fractality

A Goussev, F Quinque, J Joo, A Burbanks - Physical Review A, 2024 - APS
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 …

Different routes to the classical limit of backflow

SV Mousavi, S Miret-Artés - Journal of Physics A: Mathematical …, 2022 - iopscience.iop.org
Decoherence is a well established process for the emergence of classical mechanics in
open quantum systems. However, it can have two different origins or mechanisms …

Quantum backflow for two identical particles

M Barbier, A Goussev - arxiv preprint arxiv:2412.07898, 2024 - arxiv.org
Quantum mechanics introduces the possibility for particles to move in a direction opposite to
their momentum--a counter-intuitive and classically impossible phenomenon known as …

Quantum backflow of a Dirac fermion on a ring

VD Paccoia, O Panella, P Roy - arxiv preprint arxiv:2201.12916, 2022 - arxiv.org
We study the quantum backflow problem of a relativistic charged Dirac fermion constrained
to move on a ring of radius $ R $. Using the relativistic current operator we compute the …

Dissipative motion of Gaussian‎ wavepackets: free propagation and‎ transmission through a rectangular‎ barrier

M Bakhtiyarian, V Mousavi - Iranian Journal of Physics Research, 2021 - ijpr.iut.ac.ir
Ignoring thermal fluctuations of the environment, taking into account only its dissipative
effects, free propagation of a Gaussian wavepacket is studied in the framework of the linear …
