The potential energy is periodic in a period a, V(x a) V(x The electrons in atoms occupy certain discrete energy levels. The electron state in an atom is described by four quantum coordinates n, l, ml and ms. Using these quantum coordinates it is possible to describe the state of an electron present in at of the Bloch electrons is the formation of energy band (allowed energy regions) and band gap (forbidden energy region). In this note we discuss the Bloch theorem using the concept of the translation operator, the parity operator, and the time-reversal operator in quantum mechanics. Our approach is This is a question about the 'Second Proof of Bloch's Theorem' which can be found in chapter 8 of Solid State Physics by Ashcroft and Mermin.

Similar to the independent electron approximation adopted previously by Drude and Sommerfeld, Bloch assumes that such interactions are lumped into an “effective one- you want to see more of these videos, or would like to say thanks for this one, the best way you can do that is by becomin The central point in the field of condensed matter or solid state physics is to evaluate the Schrödinger wave equation.
