Lifshitz tails for the Interband Light Absorption Coefficient

Mathematical Physics 2009-04-01 v1 math.MP

Abstract

In this paper we consider the Interband Light Absorption Coefficient for various models. We show that at the lower and upper edges of the spectrum the Lifshitz tails behaviour of the density of states implies similar behaviour for the ILAC at appropriate energies. The Lifshitz tails property is also exhibited at some points corresponding to the internal band edges of the density of states.
