Bloch theorem In a crystalline solid, the potential experienced by an electron is periodic. V (x) = V (x +a) V (x) = V (x + a) where a is the crystal period/ lattice constant.

Bloch theorem notes


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 Bloch’s theorem – The concept of lattice momentum – The wave function is a superposition of plane-wave states with momenta which are different by reciprocal lattice vectors – Periodic band structure in k-space – Short-range varying potential → extra degrees of freedom → discrete energy bands – This is Bloch’s theorem. It has the same mathematical content as Floquet’s theorem, which is often used for functions in the time domain. If we wish to nd the eigenfunctions of H, we only need to search within a class of functions k of the form (16.15), where uk is periodic.

In the present paper, we analyze the possibility that this theorem remains valid within quantum field theory relevant for the description of both high-energy physics and condensed matter physics phenomena. Section 1.3: Blochs Theorem This theorem gives the electron wavefunction in the presence of a periodic potential energy. We will prove 1-D version, AKA Floquets theorem. Bloch theorem: eigenfunctions of an electron in a perfectly periodic potential have the shape of plane waves modulated with a Bloch factor that possess the periodicity of the potential Electronic band structure is material-specific and illustrates all possible electronic states.
