I Sinusoidal Potential in Schroedinger

  1. Aug 6, 2016 #1

    How do you solve Schroedinger's equation (time-independent, in one dimension) if the potential is V=sin(x)? Do you have to use the series approximation for sin(x) and obtain a series solution for psi? Is there some way to use Bloch's theorem since the potential is periodic? I've only seen Bloch used for a periodic delta function potential. Does anybody know what these wave functions look like?

    Bloch theorem should be usable as it is derived for general periodic potentials. Reference wise, I think you might want to look at this.
