Abstract:
We solve numerically a set of coupled integral equations due to Halperin to obtain the spectral density of a random chain of oscillators. The results are compared with coherent-potential-approximation (CPA) and Monte Carlo calculations. The accuracy of CPA is found to be similar to that achieved in CPA calculations of the density of states: the gross features of A(q,μ) are correctly reproduced; the fine structure is averaged out. The agreement between exact and Monte Carlo calculations is excellent. © 1977 The American Physical Society.
