Spectra of Anderson type models with decaying randomness
M. Krishna, K. B. Sinha
In this paper we consider some Anderson type models, with decaying randomness and the free parts having long range tails. The randomness may decay at different rates in different d…

Localization and mobility edge for sparsely random potentials
M Krishna, J Obermeit
In this paper we consider sparsely random potentials in 5 or more dimensional cubic lattice and exhibit localized and extended states. We identify also the mobility edge for a clas…
