Hello Everyone.I want to know if there is anything special about the position or the momentum representation in quantum mechanics.Every book deals with them.Why do not they work with Energy representation or time representation?Do not they exist?Basically,I feel it hard to imagine that a wavefunction [tex]\psi(\ t)[/tex] is a Fourier transform of [tex]\phi(\ E)[/tex]. Is it possible?Basically time-energy or azimuthal angle-angular momentum all statisfy the uncertainty relation as done by position and mometum.Still we generally do not use such representations (if possible)?(adsbygoogle = window.adsbygoogle || []).push({});

Can you people suggest why?
