Although quantum tunneling between phase space tori occurs, it is suppressed in the semiclassical limit tex2html_wrap_inline15 for the Schrödinger equation of a particle in tex2html_wrap_inline17 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 tex2html_wrap_inline23.
