The quantum-classical correspondence principle leads us to expect that high energy solutions to Schrodinger's equation should display echoes of the behaviour of the analogous classical systems.  One way to study this concept quantitatively is to study the behaviour of the relevant stationary states (eigenfunctions with high eigenvalue). We expect that the concentration properties of these functions will be determined by the dynamics of the classical system. In this talk I will discuss the concentration properties of the quantum analogous of classical observables such as normal velocity.
