Abstract
The renormalization-group decimation technique is exact for one-dimensional nearest-neighbor tight-binding models with or without translational invariance. Spectra, wave functions, and the density of states are calculated with little numerical work from the renormalized coefficients upon iteration. The method is used on the Soukoulis and Economou model. © 1984 The American Physical Society.
