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. We must do this for 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 similar to that used by S.L. Altmann (Band theory of metals: the elements, Pergamon Press, https://blog.csdn.net/u013795675/article/details/50197565 Note that although the Bloch functions are not themselves periodic, because of the plane wave component in Eq. (2.38), the probability density function | ψ k → | 2 has the periodicity of the lattice, as it can be easily shown. Another interesting property of the wave functions derived from Bloch's theorem is … Note that Bloch’s theorem • is true for any particle propagating in a lattice (even though Bloch’s theorem is traditionally stated in terms of electron states (as above), in the derivation we made no assumptions about what the particle was); • makes no assumptions about the … Bloch’s Theorem and Krönig-Penney Model - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online.
