Renormalization Group Decimation Technique for Disordered Binary Harmonic Chains

摘要

The density of states of disordered binary harmonic chains is calculated using the Renormalization Group Decimation technique on the displacements of the masses from their equilibrium positions. The results are compared with numerical simulation data and with those obtained with the current method of Goncalves da Silva and Koiller. The advantage of our procedure over other methods is discussed. (Atomindex citation 15:068600)
