They did not show how the theorem (5.49) or (4.198) could be applied to a linear combination of eigenfunctions. One eigenfunction one at a time, yes. But otherwise, no. I don't see how.

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.

2011-12-10 · 1. Bloch theorem Here we present a restricted proof of a Bloch theorem, valid when (x) is non-degenerate. That is, when there is no other wavefunction with the same energy and wavenumber as (x).
