The following fact is helpful for the proof of Bloch's theorem: Lemma: If a wave function is an eigenstate of all of the translation operators (simultaneously), then is a Bloch state. Proof: Assume that we have a wave function which is an eigenstate of all the translation operators. As a special case of this, Simple Proofs of Bloch's Theorem We first give a very short proof for a special case which is taken from the book of Kittel ("Quantum Theory of Solids"). It treats the one-dimensional case and is only valid if ψ is not degenerate, i.e. there exists no other wavefunction with the same k and energy E. Bloch's Theorem with proof - Engineering Physics.

A theorem that specifies the form of the wave functions that characterize electron energy levels in a periodic crystal. Electrons that move in a constant potential, that is, a potential independent of the position r, have wave functions that are plane waves, having the form exp(i k · r).

Bloch’s Theorem, Band Diagrams, and Gaps (But No Defects) Steven G. Johnson and J. D. Joannopoulos, MIT 3rd February 2003 1 Introduction Photonic crystals are periodically structured electromagnetic media, generally possessing photonic band gaps: ranges of frequency in which light cannot prop-agate through the structure.

Bloch's theorem is a proven theorem with perfectly general validity. We will first give some ideas about the proof of this theorem and then discuss what it means for real crystals. As always with hindsight, Bloch's theorem can be proved in many ways; the links give some examples. Here we only look at general outlines of how to prove the theorem: 2011-12-10 Finally, we are ready for the main proof of Bloch's theorem which is as follows. As above, let ^,, denote a translation operator that shifts every wave function by the amount n 1 a 1 + n 2 a 2 + n 3 a 3, where n i are integers. Because the crystal has translational Lecture 6 – Bloch’s theorem Reading Ashcroft & Mermin, Ch. 8, pp. 132 – 145.
