How to understand the physical meaning of the wave
In condensed matter physics, Bloch's theorem states that solutions to the Schrödinger equation in a periodic potential take the form of a plane wave modulated by a periodic function. 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 Based on Bloch's theorem, the conventional theory of electronic states in crystals could not correctly explain genuine crystals' … See more • Bloch oscillations • Bloch wave – MoM method • Electronic band structure • Nearly free electron model • Periodic boundary conditions 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: Each of these wave functions is an … See more The concept of the Bloch state was developed by Felix Bloch in 1928 to describe the conduction of electrons in crystalline solids.
