Unusual localisation effects in quantum percolation
Gerald Schubert, Alexander Weisse, Holger Fehske
We present a detailed study of the quantum site percolation problem on simple cubic lattices, thereby focussing on the statistics of the local density of states and the spatial str…

Delocalisation transition in chains with correlated disorder
Gerald Schubert, Alexander Weisse, Holger Fehske
We show that in the one-dimensional (1D) Anderson model long-range correlations within the sequence of on-site potentials may lead to a region of extended states in the vicinity of…
