Quantum Transport on KAM Tori

Abstract:

Although quantum tunneling between phase space tori occurs, it is suppressed in the semiclassical limit ћ ↘ 0 for the Schrödinger equation of a particle in ℝ d under the influence of a smooth periodic potential.

In particular this implies that the distribution of quantum group velocities near energy E converges to the distribution of the classical asymptotic velocities near E, up to a term of the order \(\mathcal{O}(1/\sqrt E )\).
