Quantum backflow current in a ring: Optimal bounds and fractality
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
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
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
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 …
