1.8: Dimensionality Reduction

This fact is easy to understand physically for the simplest case of a stationary 1D potential: U = U = U(x) U ( x). The absence of the y y - and z z -dependence of the potential energy U U may be interpreted as a potential well that is flat in two directions, y y and z z. Repeating the arguments of the previous section for this case, we see ...
