Key Details

Classical partial barriers allow small flux between chaotic regions

In higher dimensions, quantum transport transitions from suppression to classical mimicking

Scaling parameter involves flux, Planck cell size, localization length

Numerically demonstrated for coupled kicked rotors generalizing a cantorus

Quantum transport through partial barriers

This paper establishes that quantum transport through a partial barrier in a chaotic Hamiltonian system transitions from suppression to mimicking classical transport, as quantified by a scaling parameter involving the classical flux, Planck cell size, and localization length.
