    • Abstract

       

      In this paper we consider the interband light absorption coefficient (ILAC), in a symmetric form, in the case of random operators on the 𝑑-dimensional lattice. We show that the symmetrized version of ILAC is either continuous or has a component which has the same modulus of continuity as the density of states.
