Theoretical Physics II, Institute for Physics, University of Augsburg, 86135 Augsburg, Germany(Dated: February 6, 2008)A generalization of the Aubry-Andr´emodel in two and three dimensions is introduced which allowsfor quasiperiodic hopping terms in addition to the quasiperiodic site potentials. This correspondsto an array of interstitial impurities within the periodic host crystal. The resulting model is exactlysolvable and I compute the density of states and the ac-conductivity. There is no… CONTINUE READING
