= Dynamical tunneling = Dynamical tunneling describe the quantum phenomenon where a wavefunction can propagate through a classically forbidden barrier

In contrast with usual quantum tunnelling, the barrier is not necessary a barrier of potential but is, in general, a conserved quantity that prevents classical trajectories to go from one classical region to another.

The concept of dynamical tunneling is particularly suited to analyze the quantum dynamics in high dimensional systems.

At classical scale, such systems can display various degree of chaos, that results, in quantum scale
