... nucleus of charge Z sitting at the origin is described by (1) with U (x) = −Z/|x|. Note that the form and the role of the potential is exactly the same as in classical mechanics, but instead of the velocity-square for the kinetic energy we have the (minus) Laplacian. The analogy is easy to see if we ...
