Bloch's theorem states that the wave functions for electrons in a periodic potential have the form:
ψ_{n,k}(r) = u_{n}(r)exp(ik⋅r)
, where u_{n} has the same periodicity as the potential.
Bloch's theorem is used to calculate energy bands, and my question is:
Does the n in u_{n} label the different bands of the crystal?
