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. However, a Bloch-wave description applies more generally to any wave-like phenomenon in a periodic medium. For … See more 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 … 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, … See more • Ashcroft, Neil; Mermin, N. David (1976). Solid State Physics. New York: Holt, Rinehart and Winston. ISBN 978-0-03-083993-1 See more The concept of the Bloch state was developed by Felix Bloch in 1928 to describe the conduction of electrons in crystalline solids. The same underlying mathematics, however, was also discovered independently several times: by See more • Bloch oscillations • Bloch wave – MoM method • Electronic band structure See more WebMar 18, 2024 · The simplest wave is the (spatially) one-dimensional sine wave (or harmonic wave or sinusoid) with an amplitude u described by the equation: (2.1.1) u ( x, t) = A sin ( k x − ω t + ϕ) where. A is the maximum amplitude of the wave, maximum distance from the highest point of the disturbance in the medium (the crest) to the equilibrium point ...
