The theorem is named after the physicist Felix Bloch, who discovered the theorem in 1929. Mathematically, they are written See more Applicability The most common example of Bloch's theorem is describing electrons in a crystal, especially in characterizing the crystal's electronic properties, such as electronic band structure See more Bloch's theorem is as follows: For electrons in a perfect crystal, there is a basis of wave functions with the following two properties: … See more Based on Bloch's theorem, the conventional theory of electronic states in crystals could not correctly explain genuine crystals' boundary and size effects. However, about half a century ago, the mathematical theory of periodic differential … See more • Ashcroft, Neil; Mermin, N. David (1976). Solid State Physics. New York: Holt, Rinehart and Winston.
