In non-relativistic QM, wave functions are represented as a superposition of complex exponentials in which the energy/frequency is a function only of momentum/wave number (dispersion relation). This seems to imply that under the HUP, precise momentum guarantees precise energy. Are there any experimental situations in which that would not be true?
