Solid State Physics in a Nutshell: Topic 9-1: Bloch Theorem and the Central Equation
We start by introducing Bloch's theorem as a way to describe the wave function of a periodic solid with periodic boundary conditions. We then develop the central equation and find a relation between the Fourier coefficients associated with the wave vectors, k minus G, over all space.
