Bloch theorem in solid state physics

Bloch's theorem predicts partly the form of the common eigenfunctions SEMICONDUCTOR PHYSICS | … There is a theorem by Bloch which states that for a particle moving in a periodic potential, the Eigenfunctions x(x) is of the form X(x) = U k (x) e +-ikx where 2018-12-05 2021-04-11 Proof of Bloch’s Theorem Step 1: Translation operator commutes with Hamiltonain… so they share the same eigenstates.
