ELASTIC SPECTRA OF TWO-DIMENSIONAL DISORDERED LATTICES. II. IMPURITIES WHICH ALTER THE INTERACTIONS.

Abstract

Previous studies indicated that the virtual crystal approximation should not be valid for the determination of the elastic spectrum of a system of two or more dimensions in which impurities alter the interactions. In this paper, the failure of the virtual crystal approximation for such a system is demonstrated explicitly. In addition, the relationship between the failure of the virtual crystal approximation and the lifetimes of the elastic modes is discussed.
