Hi all,
In quantum mechanics, it is postulated that the physical states of a system correspond to the points on the unit sphere in the associated Hilbert space.
And yet, people freely talk about e.g. scattering of plane waves by a potential? What does [itex]e^{\mathrm{i} \vec{k}\cdot\vec{x}}[/itex] correspond to physically?
