Chapter 9 Density Matrices - univie.ac.at

The coe cient ~ais named the Bloch vector and can be calculated as the expectation value of the Pauli matrices ~a= Tr(ˆ~˙) = h~˙i: (9.26) All spin 1 2 density matrices lie on or within the so-called Bloch sphere (with radius ~a= 1) and are determined by the Bloch vector ~a. The length of the Bloch vector thus

Introduction to Photonic Crystals: Bloch’s Theorem, Band ...

Bloch’s Theorem, Band Diagrams, and Gaps (But No Defects) Steven G. Johnson and J. D. Joannopoulos, MIT 3rd February 2003 1 Introduction Photonic crystals are periodically structured electromagnetic media, generally possessing photonic band gaps: ranges of frequency in which light cannot prop-agate through the structure.

2Rather than plane waves, we should use Bloch waves nk (r) = exp(ik r)u nk r), where cell function u nk(r) satis es u nk(r + R) = u nk(r), where R is any direct lattice vector. Plane waves do not contain the cell functions, although they do exhibit Bloch periodicity nk(r+ R) = exp(ikR) nk(r). 3If collisions are purely local, then R ^ d3k

Further relations between the coefficient can be obtained from Bloch’s theorem. Each stationary solution of the Schrödinger equation for a periodical potential can be written in the form ψk []x =uk [x]exp[ikx] (6) where uk[x] has the same periodicity as the potential. From equation (6), it …
