Avarage state’s density of preudospin-one matrix eugen values

Abstract

Density of states of pseudospin-one disordered system has been considered. The random potential corresponds to the mosaic model when the system consists of domain with random values of energy inside each of two dimensional granule. The energy spectrum and states density relative to some realization of random potential were determined by Green’s function method. Assuming normal distribution of random field the average density of states has been found Here was shown that the most sensitive to the disorder is the spectrum near the conic point.
